good quality std disks shouldnt warp, I ran std disks with comp. spec pads for over 10 track days (5 or more sessions a day and 10 laps a session) and the track and back ment they covered a fair mileage and they were fine when I took em off.
I bought the discs and pad and calipers 2nd hand (about 200miles on them), but they then sat in my shed for about 6 months.
about braking hards all the time - how about nearly all the time I am a little harsh with the brakes so I am just looking for some that can take the beating and last long.
The stopping power is good enough so more stopping power would just be an extra bonus.
