I was taking my Z06 for a little acceleration testing going from 0 to 150 to 0. I felt like I had warped my rotors due to a typical warped rotor pulsing feeling in the brakes after runs. On the edge of cursing I let them cool down and now they are like glass again. Explanation? Typical or got away with it? Attending race Guru's how do I proceed to NOT warp them in the future?

Leaving it parked is not an option.

My guess is that you got some expantion and it went down when it cold off. When ever we road race or auto X, we try to move the car back or forward so that the heat is not on the disk at the same place. We also make sure not to apply the parking brake for the save reason.

I guess my question would be... WHY!? Why would you want to go from 150 to 0??? Man... that is REALLY tough on the brakes, lines, rotors... EVERYTHING! I enjoy top speed runs, and the like... but I always try to 'slow' down as looong as possible, so as not to due just that!

Dave,

Good question, its not as bad as it sounds. It is not an all out power braking situation I just start running out of pavement before a 90 degree turn that come up waaaaaay too quickly once I get up to speed.

I've had the same thing happen to mine. Always when I'm really hot lapping hard at Sandia Motorsports Park. Each time, they returned to normal after cooling. I put KFP pads on and the problem has gone away, I think because they allow the rotor to stay cooler. By the way Dave, A Z06 is doing about 150 at the end of the straight at Firebird. A very good reason to make sure the car stops from 150 albiet you need not go to zero.

Yes, I agree... I have ran Firebird many times... But that was my point exactly... actually 2 things... 1.)In Racing ofcourse you are going to have to brake hard, but never 0! And Firebird is really only about 145 down to 80, under 'hard' braking... so still not 'extreme'

2.) I would recommend finding a bit of a longer road... you will really save on the wear and tear if you can find a stretch that you can just slip it in 6th, and 'coast' down to about 120 first... and then brake... I have done 'numerous' top speed runs, including a 200+ in the '97 GTS Coupe I used to campaign in '98... but I always made sure I had TONS of shut down room!
Peace, Enjoy the SPEED! But try to BE SAFE!
