After looking at the pads again it looks like the "grooves" you see are the cross drilled holes and the line they would make is spun in a circle??? Sound right?

 

hairline crack on rotor is fine, in fact, if you dont see them, most likely you are going too slow ;-)

pads look normal. that's how mine are.

as far as brake cooling goes, i think (or i want to think) it helps. but i personally dont see or feel difference with or without the air ducts. this is true wiht my GT3, C2, m3 and cayman. i am a bad, hard braker though. i toast pads like no tomrrow. though i have NEVER experienced lack in braking power or fade of any sort even on back to back track days totally 450 track miles. i do bleed them every other track day and run motul 600.

 

 

Dell - The GT3 Cup brake ducts (air deflectors really) helped me reduce rotor wear. I also tried another trick suggested by a Rennlister. I use RS 14 pads in the rear. The 14 is a pretty harsh pad. It improves the brake balance and makes the rear rotors work harder and the fronts a little less. The result has been excellent. Improved braking, much longer rotor life in front and now some minor cracks on the rear rotors. I have done 24 track days on my front rotors - this is more than double what I got with Rs 19's all around. Note that I installed the Cup brake ducts at the same time and no doubt improved cooling helps too.

Best,

 

Nice work TD!!! Glad the new paint survived!

 

Terrific observation.

BTW, I have some great footage of the GTR... including the little 'smoking' incident.

 

That's too funny Randy! I have some video and pics of you and the GTR playing cat and mouse as well as some good in car video of me and the 964 Cup Car playing as well. Great weekend!

 

dell think you may want to call me tomorrow!!! i am worried !!! worried that you are going to love the tracks around here now that you are finally got pads !!!!!!

lol they look great i can help with the deflectors etc. i am glad you liked pads ,,, if you remember me telling you a few weeks ago the pads will outstop the tires!...

i run yellows and blacks on mine ,,, wiat till you hit the south course at vir !!! you love the pads we were hitting 1:13s and 1:14s last week pads held up ver very well

 

oh yeah i do like CMP was my outline of the track pretty close?

 

Matt you were spot on! I didn't beleive it till I actually experienced. Damn tires. The only problem I had on the track was the 5-6-7 combo. You are 100% correct, that is NOT three corners, but rather one long sweeping arc. My problem with that combo is that all the cars with R-comps and slicks were killing me there. I would catch them b/t 14 and 1, then on their @ss through 2,3, and 4 and constantly having to lift so I wouldn't smack into their @ss. Then we get to 567 and I am hanging on for dear life and if I get impatient and push it a bit I catch the marbles and start to loose the rear! Then we head out of 7 down the small straight and they assume I am not ready to pass so I have to get them before the kink or my entire lap is wiped out. ARGHHH!!!!

Let's just say, tires are up next. then new GT3

 

Yup, snake is a bitch on street tires in a heavy rear-engined car like a 996. Very difficult to get good corner exit speeds.

I just picked up a new set of shaved RA-1s for VIR with NNJR. Should be fun.

BTW . . . I can't believe you are shopping for a GT3 and you are still using streets on the 996 Crack open the wallet for God's sake

 

Baby steps Todd.....baby steps. It's not that I haven't wanted to go to R-Comps sooner but rather the track tires (which are S0-2's) still have a few weekends left on them and there is no way to justify to the wife (who also tracks) why I am throwing away perfectly good tires before their time.

As for the wallet, it seems that everybody and their mother has cracked open my wallet over the last 30 days I have been in my new home. The builder, the lanscaper, the home improvement stores, the furniture stores, etc, etc, etc. At this rate I will never get my 3!

 

If you think that's bad, wait till the bambinos come along . . .

 

Does it ever end?

 

Nope
