We're doing full Wilwood stuff on my car for basically ~$1000 rear and maybe $1200 front. Why would anyone use more factory crap? Is it really that much cheaper? A superlight caliper is $150. Brackets will be the same cost regardless of the caliper, pads are somewhat similar (Wilwood pads are probably cheaper), and my Wilwood rotors are $45. So where is the savings? I even offered to make the brackets and sell them to forum members.
Is it because they don't say "Corvette" on them?
Street temps on the rotor are more like 500*. Track temps are in the 800 - 1100 range. Not sure where the 1800* number comes from...maybe F1 or Indy cars? I measured mine Saturday at 700*, but that was after a rain session so clearly I wasn't using them as much.
Andy I'd stay away from HP+ on the street. They stop well but they squeal like a stuck pig and you'd better get black wheels, since they will become black in less than a week...
The verdict is still out on the HPS. Maybe for a beginner, but I burned up a set in about 2 laps on a buddy's Audi. Heavier, sure, but nowhere near the speeds a 'Vette will do.
The 2800F number is the melting point of iron. I was making a point regarding the warping of rotors and how it can't happen on a street car.
Yes, a race car, namely F1 can reach 1800F, without a problem, track dependant.
I am going to try the HP+... just another step up the old ladder. And yes, I have black wheels! Try them out. If they prove to be annoying, well, screw it, I can buy HPS and save these for track day. It's not like pad swaps take 2 hours on one of these cars.
My problem with the Wilwoods and such is wheel size. Sure, it's nice for my caliper to say "CORVETTE", but it isn't manditory. What is required is that the brakes still fit inside my wheel... and I am not replacing 2 year old rims on a whim like this. Makes no sense for the limited track time I do.
I will add, current factory Corvette junk, especially on the Z06 and ZR1 are sourced from Brembo. For some reason, I don't see that as junk.
