Cross-Drilled Rotors...(no slots)
 

I just ordered these babies. Note that they're only Crossed-Drilled. They're OEM size so no special adaptation/install will be necessary. I drove my Bosses NSX which has "slotted only" rotors and I didn't like the noise and the way it felt when the car would start to brake.

I should get them in about a week. By then my car will be out of the Paint Shop.

They probably won't enhance the stopping/braking characteristics, but the car was going to need new rotors sooner or later. So what the hell... :) Of course, I'll be installing new brake pads on all corners when the Rotors go in. Just thought I'd share them with y'all. I paid $160.00 INCLUDING shipping.

WOW thats a good price for 4 rotors. Post feedback on how they are after install :)

Hope I won't be posting from the Hospital:)

don't jinx yourself

I have the slotted/cross drilled ones and they started to crack on the center holes of the cross drills. Watch them. Otherwise I liked them alot and I will replace them with the slotted ones only. I was using Hawk HP pads and EBC reds. Both had much dust with slotted/cross drilled rotors.

It could have been the pad the the NSX was using that caused the noise and feel.

i heard bad things about cross drilled rotors and hard braking which can lead to cracking..hope these had ALOT of positive feedback..good luck!

There was a thread in the Suspension forum not too long ago, about drilled rotors. The consensus was that drilled rotors offer no benefit, and that it weakened the rotors. Drilled rotors are for show ........... not for performance !!

It's an Auto FD..................(so it's obvious that it's not for performance:))

This is constant hard braking where the rotor will be getting extremely hot...for street use its fine.

Thanks for the advise! I plan to sell the car in the next few months, so I hope the Rotors will hold out till then.;)

Copy That!. But it seems like some of the Members use their FDs in NHRA sponsored events on a daily basis. So to them "performance" is everything:)

I wanted these rotors also but Pettit strongly advised against cross drilled because they crack. So I am getting slotted instead.

It's pretty evident that CD Rotors would be susceptible to cracking because of the "drilled" pattern. But does data exist that would indicate cracking is evident even under normal, non-abusive use??

Also, did Pettit have Cross-Drilled Rotors in stock when you made the inquiry? (It's a rhetorical question):)

Hmm.. I've had some Brembo drilled and slotted rotors for almost 3 years. Done some auto-x and never had a problem with mine.

They'll be fine. Take a look at this year's 911, corvette, ferrari, most any higher end sports car out there. what do you see? cross-drilled rotors. Hmmm, must be a coincidence :).

Also, did you pay $160 shipped for just one pair or for four? I know what the wholesale price is on a good set of 4 brembo oem size sport rotors, and it is more than that. If you are paying that for all 4, your seller is losing money and that makes me a tad apprehensive for you.

Drilled rotors will be fine for street use, but I would check them every few months for cracks.

If you ever decide to autocross or do HPDE, I'd get some stockers or slotted rotors though.

Great price you got too. Make sure you bed them in with the new pads when you get them installed.

Agreed - cross drilled have been fine on my fat pig of a Supra for several years of aggressive street use. With your flyweight FD - they'll last forever. :)

ummm thats drag racing am I right?
And if your looking for less weight in drag racing you can use that wierd looking drag brakes...(brakes that are meant to slow the car dont just once before cooling off)
If your looking to track your car you cant just use cheap cross drilled rotors.

I was just being a tad sarcastic. I don't Race, Drift or Auto-X my FD. I just want to enhance it's appearance without sacrificing safety and drivability.

The Vegas SEMA Show featured Lambo Merciellagos, Porsche Carrera GTs, $$$Aston Martin, and even the new C6 with cross-drilled pattern only.

The price ($129.95 plus $30.00 shipping)is for all four rotors. Here's the link....

Cross-drilled rotors are fine for street or auto-x use, although they won't last as long as solid rotors. You WILL crack them at the track.

BTW, for all those mentioning Porsche, etc., these companies are doing it because the average Joe thinks cross-drilling means higher performance, not because it's so. Most of those cars use either very large rotors and/or ceramic rotors that mitigate the cracking issue. Besides, most Porsche/Ferrari/Lambo/Aston guys are NOT taking their cars to the track.

Ceramics anyone?

Anyone have a few extra bags of money? ;)
