Now that the front and rear suspension were sorted out, I busted open the dusty Wilwood boxes that have been sitting since 2005. And, so began the royal pain in the ass that has wasted far too much time. The problem with buying parts that you can't test fit right away, is dealing with the surprise factor later on. I originally ordered this kit through Precision Brakes Co, before they went out of business (or simply changed their name). They used Wilwood components, but built their own brackets and rotor hats.
Rear kit was designed for GM 12-bolt, and luckily I had no issues there. Except for the external parking brake, which protruded so far back behind the rotor that I think it will hit my mini-tub during suspension travel. Not Precision's fault, as their kit was designed for stock width axles and mine is narrowed as much as possible to get a nice deep rear wheel lip. The newer Wilwood systems have the internal parking brake, which I prefer, but I also don't want to toss a good kit away just to get a parking brake.
Rears: 12.88" diameter, 4-piston.
Now for the front brake "fun". Nothing fit well. The kit was supposed to be for the C6/AFX hubs, but I discovered that they sent me the wrong rotors. I mocked the parts up on the car, took a lot of measurements, did calculations to figure out the proper caliper offset and rotor placements. Then spent hours digging through Wilwood catalogs trying to gather up a parts list that would work.
Final solution:
I discovered that Precision had sent me four
rear rotors, with just different hats. The front calipers are much bigger SL-6 billet 6-pistons, and needed a much thicker rotor to work. How much thicker? 20.6mm up to the new 35mm size. Huge difference. I ordered a new set of Wilwood racing rotors, in 13.06" diameter.
Finally on the car:
How she sits today.
