2004 M3 at weights ranging from 2800 to 2950 lbs. Nitto NT01s and a stint on used Toyo RRs and new Hankook C51s. 4 wheel stoptech ST40/355mm BBK and brake ducting.
First a question - thoughts on whether Hawk DTC60s will be good for my setup?
Here is my pad history...
PF01s - Street driving - they will murder your rotor. Highly abrasive when cold. Very little wear on track. I suspect that I am staying within the temp range. When I had PF01s on my stock E90 M3 with stock brakes, I vaporized a set in 7 session. A lot of bite...will throw you forward harder than most pads but they have excellent release which makes trail braking much easier. There is a significant advantage in braking zones. Typically 4-6 weekends.
Stoptech SR34s - its like a PF01 except they are 2/3 the price. I suspect these are PF01 clones. Crappy part is they are only available for Stoptech caliper pad shapes. If you drive an older 911, 928, 944, or 968...you might be able to use the pad for the ST40 caliper.
Porterfield R-4 - Got some on eBay for $40 (again...same pad as older Porsches). Tried them. They are OK. They were not able to overpower the Hankook C51s and activate ABS unless I was a total idiot. Braking zones were much longer. Lasted about 4 weekends.
HPS - I had these a long time ago on my 330ci. They are not track pads. Get them too hot...pad material no longer exists. The backing plate can effectively slow the car...maybe a plus for this pad.
Pagid Yellows - Lower bite than the PF01s. If I had to guess, these have a lower operating temp range. If you can keep them in that range then these will last a long time. I got similar life as the PF01s - 4-6 full weekends (2-3mm wear per weekend)
Stoptech Street Performance Pads - They are OK but once you overheat the pads they turn into useless bricks. Usable in a pinch - probably a little less performance than the R4s except you HAVE to keep temps under control. I could drive a smaller venue like the Milwaukee Mile w/ infield with these and have no issues. If I put on SR34s, I would easily run 2 seconds faster per lap.
Hawk DTC-70 - At Road America in my E90 M3, I smoked a set of these in a day with dual driving duty. Road America is by far the worst track for brakes I've been to. You can hit 140mph on 3 straights and 3 hard down hill braking zones (one is 145mph to 45mp downhill). Not too different from PF01s. Probably just burned these up from overheating. Can't be too critical since we burned up Pagid Yellows in 1 day too!
Carbotech XP?? - At Road America in my E90 M3. Overnighted these out of desperation. These were crap for track duty. They didn't even last half a day.
BTW...I estimate brake cooling extends the life of my pads by over 50%. I've ran one set of SR34s for 10 weekends. Just don't have enough data to say 10 weekends will be a consistent number.
