drilled / slotted / solid ??

just thought i would post these pics that i have taken over the years. I dont think i would call Porsche out on using drilled rotors especially since most privateers have factory cash and engineers working with them. On the other hand look at the factory C5R - solid, and 911 GT1 24 hour car - solid, just my $.02

the last two solid pics are carbon? i think?

Yup.

Carbon rotors are an apples-to-oranges comparison.

well either way, there are a lot of posts saying that drilled rotors are not for competition use. the first pic, the 911 gt3 rs, kinda disproves that...like i said before, i wouldnt question the engineers on using drilled rotors.

The old drilled or not issue...... It will go on and on. The folks that say they arent for track use have some legit concerns. Then there are ALOT of manufactures that are using them on race cars. And will continue to without regard for the nay sayers.

The way I see it is yes, there MAY be a concern with cracking. But that small concern doesnt seem to hold back racers using them.

And for the semi race, mostly street guy. I dont even see a concern.

But... This long lasting drilled or not drilled rotor thread will out last me. JR
