I'm looking at this kit and I think it will work, but they don't seem to offer anything for the rear.

You'll need to confirm the hub offset which shows as .88" on the spec sheet.
Can these be used w stock rotor?

That's what I am running on my front of my 91 with 17s Fikse FM-5s. I know you can run the C5 brake upgrade under a set of A Molds. I'm 90% certain that will fit under factory A Molds as the guy I bought my set from was running them behind factory sawblades and I believe the sawblades are tighter than A molds.
However your mileage may vary. GC

You would need to go with the street shop upgrade with the DPC56 C5 direct replacement 4 piston wilwoods for a stock C5 rear. If you want to retain your parking brake
The registry has a group buy going on on the street shop upgrade at the moment in the registry only section

No they can't. However the kit he is planning on using or buying comes with the SRP Wilwood drilled and slotted rotors as a part of the kit. It identical to my kit on my 91

That is an readily available kit. Actually is was never offered as a kit. Assuming it is on your callaway it was created by them. Do you have any pictures?

You will be hard pressed to get a 13 inch rotor on the rear and the calipers to clear your 17 inch wheels. 18 inch all day.
Also you will lose your parking brake unless you go with the old school extra caliper or you go with the street shop mod with matching Wilwood script calipers front and rear as I suggested. GC

aren't our factory J55 rotors 13" or are they 12.88?

Factory fronts are 13 inch and rears are 12 inch. I think Wilwood makes them a little smaller with a different offset so they will clear. The secret to the brembro's clearing are huge offset hubs at least on the 10-15 year old setups I saw. I stuck with 12 inch rear rotors and Wilwood 4 piston DPC 56's. More surface caliper area meets the rotor vs the 13 inch anyway and I wanted to make sure the calipers cleared within my Fikse FM-5s. also the DPC56 are plenty big enough

This kit comes with Mr. Parker's mechanical brake. This install requires 3/4" cut from parking brake cable bracket where the parking cable terminates at the rear of the car and two clevises and M6 (I think) bolt with head cut off to join clevises between the parking brake cable and mechanical caliper lever.
This was not totally sorted out kit when I bought and installed it but worked out fine with some additional engineering.

-=Jeff=-
11-01-2016, 12:04 PM
Not a Direct answer but:
on my car.. I had C5 front brakes, fit behind the A-mold. I swapped to the Shelby, to fit I needed a spacer. Now I have wilwoods, like your link, with my Shelby's and no spacer. I believe they will fit without issue. in fact I believe Bob Gillig has those brakes with A-molds and no issues.
Maybe you could convince GC to bolt up an A-mold from his 90 to his 91 to confirm for you

I am running Shelby's myself, but just want the option to run my A-Molds. Glad to hear they work with the Shelby's.

I did not.. I ran out of $$ LOL
The brake adapter is ~$700 before group buy price..
Rear brakes are ~$1700, although the have a DPC kit for ~$800
So at the time my cost was $2400 and I did not have that in the front kit that I bought used. I am using stock rears. but I had problems with my parking brake working (does now), but at the time I looked at rear early C4 drums with early brakes, although now I am not sure I would do anything, I guess I would upgrade to the C5 DPC kit and re-shoe my C4 parking brake pads and run those potentially, never gave it thought after getting the parking brake to work

I've been resisting the urge to pop into this thread and ask, are big brakes really needed?
I've punished my (mostly) stock brakes on mountain runs and race tracks, and I haven't noticed them being unable to keep up with the tires' grip.
I admit big brakes are very cool, but considering the expense (and my perceived lack of need), there are plenty of other places to spend money to improve performance.
I am open to being educated if there are times when people have experienced significant shortcomings of the stock brakes.
Thanks.

For a Stock ZR-1 I don't see the necessity. The OEM systems are pretty good. However, when you start stroking the motor to push the HP envelope you need to upgrade the transmission, The cooling, beefing up the half shafts u joints, the suspension and the yes the brakes etc. A lot of folks will spend upwards of 10-15k on their motor to make the car faster beyond original design. Now apply that to stock parts and you have exceeded design tolerance and that's when stuff starts breaking. If all about safety once your surpass the OEM limits of the car. Its a little harder to stop a 500 hp ZR-1
XfireZ51

As one of those that's gone through the process of upgrading to big brakes,
I am going to tell you it was a very worthwhile improvement.
Had C5 brakes on my first ZR, the Black Rose came w Brembos on the front.
As GC says, if you are taking a stock motor from 375 up to ~ 540(like mine)
the Z06 brakes provide a great sense of security. They require less pedal pressure to stop in the same distance. W similar pedal pressure they are going to stop quicker w much less chance of lockup.
They do look great, especially if you are using a larger diameter wheel like the stock C6Z06 star wheels.
Worth every penny in my book.

Thats part of what is making me think alot about this. Those look like the same calipers to me. The difference has to be the rotors, and how the parking brake functions. I can tell the Hat on the 84-87 hit is taller or deeper, I guess the parking brake kit goes inside.
I emailed the guys doing the Street Shop mod and got some pictures of their parts, which look like they have to fit inside that part of the rotor, so I'm not sure how the C5 Rotor would work at all.

To clear things a bit.. the C5 rear and C4 rear calipers from Wilwood LOOK the same but are different:
C5:
Lug mount
2.46 Piston Area
One piece rotor in the DPC kit
C4:
Radial Mount
1.98 Piston Area
2 Piece rotor/Hat (hat is also iron for parking brake)
Stock C5 rotors have the shoe surface in the hat, looks can be deceiving. remember the caliper brake surface is not offset the same as the C4. I have looked into using the C4 parking brake assemble but you cannot mix them with C5, The C5 drum diameter is bigger. but the C4 is more like a true drum brake. I have seen adapter brackets for stock C5 calipers/ rotors for 84-96 C4s, but the 89-96 will lose the parking brake. with the 87 style you need custom shoes on the brake (thicker)
I think if I got the Mounting brackets and calipers from the Wilwood kit, I could make them work on my car with all the part I currently have (that are not currently on the car)

So if I do this Street Shop mod, and use the C5 Calipers and Rotor, longer wheel studs etc. Will my parking brake cable reach to whatever it needs to activate the different parking brake?
Also still wondering if my wheels would poke any more than they already do. Shelby's are right to the edge of the fender.

No, you need the lokar cables to run from the 'front' parking brake cable and then can be adjusted
for the Shelby's, I am still not sure why the longer studs are needed BUT you can move the Shelby centers outboard and get the wheel to tuck in if needed

if the vent vanes are straight up and down I can see that.. but I have seen right and left and they are truly right and left
Next time you see a 2016 or 2017 Z06 & Z07 take a close look at their rotors!

Oh I know about those..
Last time I checked , this thread was talking about C4 and C5 brakes.. NOT C7
It helps when you actually add the information first..

I asked Trey at streetshop about the longer wheel studs being needed.
he says "Not true. Hub width and stud length remain unchanged unless the wildwood rotor hats are thicker than stock."
Anyone know if the wilwoods are thicker, and if so by how much?
FWIW the front Wilwood hubs are about the same as stock from what I recall. I did not use a micrometer to check them for accuracy though
I would say the rear will be stock thickness since they are iron. I am thinking you will not need the longer studs.

Folks on the other thread said you need longer studs. I assume the hub and the rotor make that so ?
just the rotor.. the bearing assembly bolts to that hub assemble from Street shop, which has nothing to do with the studs, that is why I asked as it was not completely making sense

Since 1960 all GM disc brake rotors are right hand only for all production vehicles C4, C5 and C6 are included.

so then the vanes will be directionally backwards on one side?
the 13 J55 had directional vanes..
as did the C5 brakes I had on my 89.. so how is it the same number?

For street use directionally doesn't make much difference.
