On a 3,500 lb car that will see 3-4 track events per year at VIR and a few autocross events? Prior owner installed these but it may be cheaper to convert to C5/C6 rear brakes since the cost per rotor is about $175 less than Willwoods.

Which Wildwood rotors? What diameter? What pads?What are the front brakes? Do you have a properly adjusted proportioning valve? Brakes need to function as a complete system. IMHO seems rear rotor wear should be one of the last issues to plague a brake system.

I don't have the part numbers as prior owner no longer had receipts. I contacted Willwood and they told me where to find part numbers, so I'll work on that. Best guess is they are Dynalite with unknown pads and the rotors are 12.19"

Fronts are Willwood but I"m going to replace those with the Kore3 14" C6 kit.

This guy.

I've got two years on a set of 11" rear rotors on my car, 15 track events. Replaced the fronts once already and turned the rears when I replaced the fronts.

But your mileage will definitely vary.

Andrew, I just read your web log on your rear brakes. Very nicely written and very informative. You did an excellent job on it.

Thanks! I hope others can learn from my pain.

I know this is an older thread but I had custom rotors made for less than the stock Wilwood GT rotors.

What was the cost per rotor at Coleman Steve? I know prices change all the time but just curious.

It has been about 8 years since I assembled the brake system but as I recall the closest spec Willwood GT rotor I needed was just a little over $200ea and would still have required some additional machine work to fit my Moser floater rear end hubs. The Coleman custom rotors were around $120ea as I recall and I was able to spec them exactly as I needed them.
