Big Brakes Needed

[Blue Flame Restorations]

Hi all. I want to utilize either C5 or C6 ZO6 brakes. I know there are some caliper brackets and kits. I searched the threads but would just like to be able to take the list for what I want and order it.

I have GenII Dymags that will accept some huge brakes. I just don't know how huge????? They are 17x11 and 17x13 wheels.

I "think???" I want to stay with Corvette brake calipers and rotors, preferably.

Any advice?

Hi Brett, Rick from NJ ( rickyrj1 ) has a line on a company that makes adapters to use the entire C6 ZO6 brake package.

[Daniel_Mc]

The AP Racing Calipers in the ZR-1 are much bigger than the Wilwood's on the 89 and the GEN II's clear them with no problems. I feel like you will be just fine with the stock C6 Z06 stuff, rears especially!

Daniel, I appreciate the input regarding the Dymags we both have. I figured they'd clear just about anything. Do you have spacers on the front 17x11's?

[Daniel_Mc]

No, no spacers up front but the hub looks as though it is just a bit thicker than the stock units. The wilwoods have one heck of a spacer built into the hat. I do not know why but the car had spacers on the rear... It has a bracket between the hub and the rear knuckle that is made so the "old" front J55's could mount out back. The rear uses the stock front hardware. I have removed the spacer and put the rim on and do not see where it would rub at all but put it back on for now. If you would like pictures of anything just let me know of what and what angles.

Daniel

[Blue Flame Restorations]

Thanks, Daniel. I'll most likely go with the C6 Z06 setup with the aftermarket brackets.

[XfireZ51]

Brett,

You need 18" wheels for the Z06 calipers. Won't work on 17s. I'll sell you my Brembos and convert to Z06 brakes.

Man, that sucks! I'd hate to think I'd have to do C5 Z06 brakes. I'm not getting rid of my Dymags though. :mad:

I guess I need to look at some Z's with C5 calipers.

How much for the Brembos, Dom?

Very doubtful you can fit C6 Z06 brakes. (rears maybe, but fronts almost certain they won't fit)

C6 Z06 brakes are very pricey.... If you go "cheap", they are 2k.

C5/C6 brakes are a great value @ under $600.

[Blue Flame Restorations]

I just want to get an idea of what I need to buy next month at Carlisle. I plan on spending some serious $$$ on everthing I need ZR1. I want GM bigger brakes on the 92 project car. It would be nice to buy everything I need while I'm there.

I also need a perfect hood and front bumper assembly.

What does Bob have on his 427 car?

What does Bob have on his 427 car?

Wilwood 6 piston in the front. I think 4 piston in the rear.

[XfireZ51]

What does Bob have on his 427 car?

I think he and Al have Wilwoods. I would do the C6Z brakes as a straight up swap for the Brembos. You buy the C6Z brakes and adapters, I'll give you the Brembos w rotors and pads

I'm contemplating what to do. I just looked at the C5 Z06 calipers on ebay and the brackets for them. About $600 for that setup. Brembos are intriguing though.

[Aurora40]

C6 Z06 brakes are very pricey.... If you go "cheap", they are 2k.
Is the adapter hardware for the C4 pricey? Because for $2k you could buy all brand-new GM calipers, pads, and rotors shipped. Used should be considerably less than that.

I've been keeping an eye on them because I have a friend with a C6 in the market for them.

To the OP, it is the 14" rotor diameter and the fact that your wheels are only 17" in diameter that makes them unlikely to work. Not any kind of spoke to caliper clearance.

[Aurora40]

I'm contemplating what to do. I just looked at the C5 Z06 calipers on ebay and the brackets for them. About $600 for that setup. Brembos are intriguing though.

I thought the adapter was like $120ish for C4's. You could probably find used calipers for <$100, rotors can be had for like $25 per from NAPA, and then some Hawk pads for another $100 would put you well under $600.

You can also use C5 regular calipers or C6 regular calipers, to keep your options open when going used.

Is the upgrade for looks? Or for more braking capacity?

[Blue Flame Restorations]

AUrora40, thanks. Actually looks and performance. Mostly looks though. I like the looks of a 2 piece rotor, drilled/slotted. I am understanding that a 13" rotor is my max size with the 17" Dymags. I'm ok with that.

May do the brackets and C5Z06 calipers.

[Aurora40]

Ok, maybe more like $150 for calipers vs <$100... I thought they were cheaper. Two-piece rotors are pricey, and you might feel compelled to upgrade the rear to match, which is more pricey. I spent $900 on 4 two-piece rotors on my car, I don't think I'd do that again... They looked cool, but so do 9 C-notes.

It's hard to beat the C5+ rotor for performance, it's quite a bit thicker than the J55 front rotor. The caliper might not be super blingy, but the C6 version of it is pretty clean looking. Maybe Mike can chime in about their performance. He has a friend with an LT4 race car and uses C5 brakes. Mike was impressed with their abilities on the track. And they are cheap!

Just FYI, if you only want looks, Baer has that 6-piston caliper with pads (C5 sized) that uses the stock J55 rotor for $1k. There'll be some performance upgrade from the extra clamping force, but mostly it looks cool, and uses standard replacement parts (C4 rotors, C5 pads).

I have a spare set of the adapters made by Exotic Muscle. You're welcome to them.

Brett,

LG had a Wilwood SL6 set up for the C5 that a few C4 guys converted over and used. They were running the C4 to C5 adaptor brackets and the Wilwood Caliper. The LG set up utilized the stock C5 rotor so you could just purchase any "Stock" style 2 piece rotors and that should achieve the look you are going for. The Wilwood site shows the calipers in red and black so you may have a choice. I looked on LG's site and did not see the kit, it may be discontinued but I know it fit behind the GM stock C5 Z06 wheels and GM A-Molds. The only reason I stayed away from this set up was I had heard under hard conditions the pistons in the SL series of caliper had seized causing extreme pad wear and possible loss of braking. I have never seen it or even met anyone that had but I was skeptical so I went the route that I knew worked. Another option is the Wilwood?s from DRM (http://dougrippie.com/?p=933) for the C4; I am running this set up with absolutely no problems and the rotors are nice and thick along with the pads. Just my .02 but I feel a thicker rotor is better than a larger diameter one. Stop Tech also makes a nice set up but I believe it is the front only for the C4.

Daniel

[scholtmj]

13" Baer 6P on my daily driver. C5/C6 pad size so lots of compunds. I have 275/40-17 BFG KDs up front and you can lock them up whenever you want - lots of stopping power. I was also pleased with the pedal feel after installation - near stock stroke length.

Dainel, thanks for the great input. Much appreciated, as always. This will help alot.

i need to look out for c5 calipers at carlisle

[FU]

I like using a bias spring in the master cylinder when converting over to C5 brakes. The bias spring reduces the front nose dive a bit when hitting the brakes.

$500 alone for the rear hub needed for the emergency brake. Front adapters are about $150 to $200.

Need different SS lines, rotors, calipers, pads, etc etc etc.

Ask Ricky... VERY pricey!

C5 / C6 brake upgrade is the best for the $$$$$ and looks great!

If you just want a look, the Baer 6P looks pretty nice.

Here's my car with two-piece rotors and the 6P caliper. I had about $2k total into the brakes:

http://aurora40.dyndns.org/Hometown/corvettezr11990/fs/small_DSC00211.JPG

The rears are "plus" rotors, they are 13" vs 12", and come with a caliper relocation bracket. It was only $50 more (on ~$500 rotors) for the "plus" upgrade once I decided on two-piece ones.

I'll tell ya, I really miss how good that car looked...

The C6 ZO6 fronts were a staight forward set up, simple adapter. I bought the new front calipers & rotors form a forum member for $450.00 shipped from VA. (great deal) The rears I had to pay small discount retail, I beleive $600.00 cals & rotors. Hawks pads, extra as well as new SS lines. The rear hub adapter was another $600.00 + & I needed to get some new C5 e-brake cables to make it work. Once I put the fronts on I had no choice but to step up and do the rears(the caliper was to small sitting in the wheel) I am more than happy with the final result eventhough it cost me a little more coin. Like Dom I run the OEM ZO6 wheels. I will be at Carlisle on Friday morning if you want to take a look

So you run an 18" wheel? I plan to run my massive Dymag GenII's 17x11 front and 17x13 rear wheels. I think my max size rotor is a 13"??? Right????

Probably do the C5 Z06 calipers with adapters and anything else I need to make it work. It would be nice to have a parts list of everything I need to make this setup work before I go to Carlisle. Anyone have a quick list?

Brett,
I'm currently running 10"x18", 58mm offset Fikse Profil 10s on the front.
Before I was running the same 13" C6 brake setup with factory 17" A-molds which were at the limit clearence wise for those particular wheels.

[XfireZ51]

Thanks, Kevin. That helps tremendously.

The C5 rotors are slightly smaller @ 12.8" rather than the J55 rotors @ 13". They are thicker however.

So what are the differences between the C5 and C6 base calipers?

[ZZZZZR1]

So what are the differences between the C5 and C6 base calipers?

None. Identical. Z51 is different.

[XfireZ51]

C6 Z51 brake uses a 13.5" rotor. However, won't work on 17" wheels.

[Blue Flame Restorations]

Phil, Dom, thanks for the rotor sizes. I know it's a lot of questions. I feel like I should already know the answers but I keep telling myslef, "You have never had a ZR1 to drive daily".

I just want to make sure that I mod the car with something that I'll be happy with. I don't want to do it twice. I don't mind dropping $$$$, but I want to spend $$$ it wisley.

Brett,

The C5 brakes are very good. They are not incrementally better than the J55s in comparison to having replaced 12" rotors w the C5s. However, if you are interested in using 17" wheels, the C5s are a value for the money.
Lots of rotors and pads to choose from also. Or get the C6 version which has a more stylized script on the caliper.

[Blue Flame Restorations]

At least I know what to shop or at Carlisle next month.

Thanks to all!!!!:handshak:

[Jagdpanzer]

So what are the differences between the C5 and C6 base calipers?

Mounting interface is the same for both C5 Z06 and C6 base calipers.
C6 caliper hats are of beefier construction, have larger raised "CORVETTE" lettering, and have a cleaner overall look in my opinion.

[XfireZ51]

At least I know what to shop or at Carlisle next month.

Thanks to all!!!!:handshak:

If you find a worthwhile set of C6Z calipers, let me know.

Here are C6 base base calipers powder coated red and 2 piece rotors I got from Ricky when he went the C6 Z06 route.

http://i17.photobucket.com/albums/b79/MRBLU/DSC00203.jpg

They do look sweet Phil, just so everyone knows they are C6 brakes that came off a Z51 option car. I was told at the time that they were a small improvement over the C5 ZO6 & stock C6. when I had to order the Baer 2 peice rotors, I had to specify Z51 brakes. Hope this little bit of info is helpful. Phil will need all the stopping power he can get after he puts in his WAZOO monster motor :-D

[Aurora40]

What is the rotor size with this setup??
C5 and C6 base rotors are 13x1.25". For comparison, your J55 rotors are 13x1.1". The C5+ rotors are noticeably thicker, they will take more braking to heat up than the J55's. If you stand them up next to each other, the C5 rotor is slightly shorter, but both are close enough to be called 13" rotors. The thickness of the rotor, plus a slightly larger caliper, is where the performance increase comes from.

There is no performance difference between C5 and base C6 brakes. However there is a cosmetic difference. The C6 caliper is painted grey and has larger "CORVETTE" lettering. The C5 base caliper is just rough aluminum, and the C5 Z06 caliper is painted red. The C6 Z51 uses the same caliper, but a different caliper bracket. It has a 13.5x1.25" rotor. However, the rotors are expensive, and might not fit in your wheel.

C5 and C6 rotors are also interchangeable but different. C5 rotors have directional vanes, C6 rotors have radial vanes.

[HAWAIIZR-1]

Brett,
Sorry to hijack your thread, but I now want big brakes and see there is a lot of discussion here already. With the DRM coilovers on the way, now is the time to upgrade brakes if I'm going to do this right.

The problem I have is like Brett, I am not willing to get rid of Dymag IIs to have bigger brakes even though it limits me. It seems the C5/6 might be the best way to go even though I was thinking of SSBC Tri-Power; not sure if rears will fit.

The other problem is I am still moving around the world and my stock 90 wheels (pc'd black center) are my shipping wheels so even more limited than the Dymags from what I have read on other posts.

So if I am not willing to get rid of my 90 OEMs to use for transporting the car, I can't do any upgrades? I read that the C5/6 can't fit in the 90 wheels. I'm trying to confirm with SSBC about the Tri-power (all it says is it fits 17" wheels), but not all 17" wheels are the same according to the information I have found so far.

Thanks for your thoughts.

Craig

[XfireZ51]

Craig,

The Brembos I had originally would fit under A molds.

[HAWAIIZR-1]

Craig,

The Brembos I had originally would fit under A molds.

Thanks Dom. I guess A molds have more clearance even though 17" wheels and my Dymag Gen IIs have more clearance than the stock 90 MY wheels? I'm not sure how to confirm this other than with folks that have upgraded with 90 MY wheels. Worst case is I give up on the 90 wheels (sell them) and ship the car with the CCWs or just stop moving round the world and settle down already.............if I want bigger brakes.:confused:

[Blue Flame Restorations]

I like my C5 Z06 front calipers with the Dymag genII's

Craig,

Wilwoods would be an option possibly.

[GOLDCYLON]

Thanks, I just have to figure out a way to fit them into 90 MY wheels or get rid of the wheels.

Just go to the 96 CE/GS calipers, they are a direct fit and have the correct corvette C4 Script. No adapter brackets required.

GC,

Thanks for your thoughts and what I bought some years ago when I first got my Z and it was stock was what I was told are GS calipers.

http://i78.photobucket.com/albums/j86/hawaiizr1/zr1.jpg
My understanding is they are a slight improvement over the J55s as you mentioned, but looking for more improvement and it seems I might have to just get rid of the 90MY wheels to get what I am looking for. I am still waiting for SSBC to get back to me about some of their products are might fit in the 90 wheel, but still might not be much of an upgrade over the older J55s. I still have limitations with the Dymag Gen IIs, but they can at least fit the C5 brakes (again, not a big improvement?). Thanks for your thoughts.:cheers:

Ricky,Craig and David, thank you for the comments. Yes i am doing the rear also. These calipers are really massive it makes the c6 z06 calipers looks small.

So is there anyone with experience upgrading the brakes in their 90MY OEM wheels? What fits? Thanks!:cheers:

Daniel

[XfireZ51]

So are the ZR1 brakes big enough to accommodate the rotor? They appear to be 6 piston like the Z06?

[shaynezrl]

The c6 zr1 comes with brembo 6 pistons calipers. The difference is the size... It is a bigger designs. The rotors are 15"1/2 size.

Right. So they are 6 piston but larger to accommodate the rotors which are
1 1/2" wider in diameter. Aren't the Z wheels 19/20"?

Hey Guys I'm not trying to change the topic or hijack , But For me since I wont be on the track and for me and what I do the stock system is fine unless I can inprove the brakes with little cost ( I'd rather at this point put $$ into exhaust etc ) But for inexpensive improvements etc would stainless lines and different rotors etc help? heres a ebay link to show what I was looking at ? http://www.ebay.com/itm/290702851807?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1438.l2649
I hope the link will post.. Thanks

Corbusa. Those will not work on the Z,. We have J55 (13") fronts on our cars OEM

I think you have a point about brake upgrades and depending on how you drive the car and the purpose. I also think think that stainless braided lines have a little help and purpose as do upgraded rotors/pads. I would warn you to you make sure you check on brand and quality as you get what you pay for in most cases. Besides as Jeff said not fitting our application, the quality of the ones you mention are probably made in China and might not be of the standards you desire for something as important as brakes. If you have done high speed runs and or even in spirited driving with close calls that better braking would have helped, then you probably want to upgrade. Otherwise it seems our brakes are not that bad for the average user. In other words, in my opinion not every needs to or should upgrade their brakes.

Give me brakes as good as I can get because I never know when I will need them. All it takes is some bozo who doesn't know what they're doing.

Thanks Guys , Good info aboutteh ebay stuff not fittings and china made ( probably) . Xfire you are probably correct , But i will have to do this a little later .. Wasnt there a link to a place that made an adapet setup for dual calipers ? I remember a thread about it sometime back.. I did a search here and on the net and couldnt find it.

I would do the C6 Z51 brakes before the dual calipers. Besides, not sure that setup is even available anymore.

SO we have 13 in front and 12in rear?

Actually the Z51 is a 13.5" rotor. Gives a bit more wheel clearance than the Z06 caliper although you still may need 18" wheels.

The entire premise of the ZR-1 was to be able to bring in a dual pattern camshaft for vacuum and emissions reasons. As you know, it is very complicated to bring in the secondary ports. The L88's had little vacuum, and Chevrolet did NOT want the public driving that car because the brake booster would not work in traffic, and the car could not stop or go into a turn at 160mph without a booster.
The LT-5 was a modern solution to this dilemma.
I specialize in HYDROBOOST power brake conversions, which run off of the p/s pump, and need NO vacuum. The stopping power is incredible, as 2000psi is available to the calipers, even at idle pump speed. I have done these before on Big Block C-4 conversions, but will be prototyping a Hydroboost on my own car soon. I will have the hoses and brackets dialed in for those who want the very finest in brakes. I will use the more common 1" master cyl, eliminating the weak and expensive 13/16' or 7/8' original master cylinders. This will give a much firmer pedal feel.
With High pressure, the car stops in nearly half the distance. This has the effect of not heating the rotors, and eliminating the need for giant rotors.
