He sure surprised me with the 1:52 in timed runs. I also plan on being at Chuckwalla in Jan. that kind of talk must sting the East coast guy's.

Mike I thought you were running Hoosiers as well. Were you not? If not, what were you running?

Mid day Sat. I put a used set of Hoosiers on mid day Sat. after I looked at my rear tires Kuhmo V720 looked like they were going bad.

Looks very similar to mine, lovely...Do you have pics of the rotors after track use? I like seeing them like that for some reason lol

TRAKCAR

20 track days, half of them easy (Ring)

^^^ The materials on the new factory rotors are impressive. WAY better than the 997 stuff.

On the brembos, I think he did 2.5 days on the car, and there were no stress or crack marks on the rotors at all. Granted button willow is not that hard on brakes.

On my car (not the same pace as a 991rs obviously) the type 5 fronts have 10 days and still look fresh. Martin is running a few seconds a lap faster than I am, primary braking zone speeds are actually similar, he's just got more sack than I do in some of the high speed areas.

TRAKCAR

Right.

Without hijacking this thread, I think slotted are better but the 991 OEM rotors are lasting very long, I have 15 days on my second set and even using up used pads and hammering the brakes very hard at Sebring Homestead and PBIR (Derek Bell set all 4 corners just about on fire)they are still not cracked through but they are looking pretty tired.

My rears are original and looking fine.

Awesome pics Martin! Mr Purple FTW!!

I put the slotted rotors on before the first track day. I did 14 sessions with the car and the rotors still look pretty much new. I did have to get used to the RT10 brembo pads as they don't have as much initial bite as what I'm used to with the Endless ME20s. My AP rotors in the front on my GT4 lasted 24 track days and the rears still look good.

usctrojanGT3

I'm wondering if it makes sense going with a more aggressive pad in the rear to balance out the brake bias? I'm actually going to try that with the GT4 first.

Jono809

Oh, yeah I was being weird...I just like to see the rotors when they get a bit of pad transfer on them and start getting that slightly blue-black hue to them...

Never mind me, I've only heard good things about the Brembo discs, very popular with the regular track guys here

Good to see a fellow Trojan at the shop. Fight-on!
