Rear Z06 Caliper Install

Shims worked as advertised. Thanks. I emailed Tray and suggested he at least notify people that this may be necessary. Better yet, maybe include an extra set of shims as part of the adapters. He indicated that SS had also run into this but rarely. I imagine they don't install ABS in the C4 chassis mods they do.
Once I had done this, I was now able to mount the rear calipers. And what great timing because the Lokar universal cables and clevis' were delivered yesterday.
So fitting those will be next. Got them from Amazon. I thought I would try adjusting the star gear for the eBrake while I had the bearing carriers off the car but they seemed to be adjusted close enough. Tray recommended that any adjustment be done using the cables rather than the star gear.
Will also be replacing pads on front calipers with ceramics to match rears.

eBrake measuring and install now done. Meanwhile, I've been gravity bleeding the brakes. Rears seemed to work but fronts are not. Hmmm. Right now the issue is how to keep eBrake cables away from wheel drum. Dmod1, any suggestions?
Also, another observation. Spare tire is worthless at this point. It won't make it over the rear caliper, so no real sense in keeping it on w the weight etc. My jack was in the spare along w a tire bag altho I also had a second tire bag in the rear bin.

I like the brakes on your car,Dom,and want to install the same set-up in front of my 94,in the future. It just seems like the emergency brake set-up is needlessly complicated,not to mention expensive.
If you had it to do over again,would you?
Honest question.

edit: Never mind the above question. There is a thread over on CF in C4 Tech that explains the problem.

Clint,

I took this path pretty much w my decision of mounting the Z06 wheels. Having decided on those wheels, which I LOVE, the calipers become a requirement IMO.
One is made for the other aesthetically. Their performance is amazing. I never "think" of the brakes. They just do exactly what I want them to. Thee fronts are no more complicated an upgrade than C5 calipers. The rears could be simpler if u are willing to be satisfied w a line lock. However, the C6 eBrake is not complicated. The tedious part of the rear calipers is getting the cables sized correctly, which is problematic on your back in 30F weather. A lift would substantially make things easier.
Using the 19" wheels w the stock rear calipers worked just fine. BUT, they simply looked too puny. So yes I would do this again. It was always the overall plan.
The trick is finding a set of C6Z calipers. Careful shopping gets u a great set of brakes for $600-800. With associated pieces, ie pads, adapters, cables etc. it's not an inexpensive upgrade. But this is the way I want the car to look and drive.
With the additional power of 450+, I really appreciate the added margin for error the brakes provide. Along w this upgrade, I also replaced bushings, tie rod ends, so really excited to see how the overall car feels. Good way to keep sane in a pretty lousy winter.

XfireZ51,

Your brake set up looks great! May I say that I understand a sense of achievement you feel. I went in another direction with 4 pot Wilwood set up for the rear w/ Mr. Parker mechanical spot caliper set up for the parking brakes - different solutions but to reach the same goal!
Congratulations. Looks great!!!

USAZR1,

My answer to your question is "YES!".
With me it was the 18" Fikses - completely agree with XfireZ51's comment. My Fikses made me do it.

Secondchance,

any info on the Wilwood with Mr Parker? cost? part numbers? etc

a 17" GTO spare would probably work on the rears. For the front, you would have to get like a 2" spacers- I've seen it on CF that some guys had used them for drag skinnies on Z06's over there with big crazy spacers.

There is also the elusive Cadillac 18" CTS donut that has even better clearance for retrofits like this.

XfireZ51,
I ran the cables above and zip tied them to the lower shock mount. You might be able to see what it looks like in one of the pictures I posted.

I thought the cable housing sizing was a pain. I hope you had a much easier time of it than me. I ended up cutting each about 15 times to get that perfect length so that they ended up about halfway in between the lowest part of the knuckle and the wheel without rubbing on anything else.

Cost - rear kit with Wilwood 4 pot and parking brake is about $1,650.
I found out some additional engineering was needed - cut down/re-weld for parking brake anchor brackets (in order to work with OEM cable) and one side of parking brake had to be shaved by 3/16" plus 3/16" shim cut to add to the inboard (caused by spot caliper not quite lining up). Talk to Randy.

Spare tire solution is a CTS-V spare. However, I understand that the hole in the center has to be machined to fit our Z. Expensive-yes. Elusive-not so much.

Dom & Yun: I'll be installing 19" CCW's probably next week so I can certainly understand the motivation to add big brakes. This thread has just added fuel to the fire.

On the front of our 94,the two options I'm considering are the complete C6 Z06 set-up or just install a pair of Baer 6P's on its front Eradispeeds. Cost would be about the same but the Baer calipers would be a much simpler mod.
However,the 14" Z06 rotors are hard to ignore.
