Anyone here have drilled rotors?

[Mark]

Curious as to if you have had any problems with cracking.

i would do it your self. im sure they drill them then heat treat them or somethin.

i do on my hatch mark. I haven't driven it much lol but they have been on there since mike had it and I havent seen any stress on any of the rotors on the front of the car. I have slotted on the back on the gsr spindles. stops like a champ though.

Thats good to know. I have heard several stories of how the drilled rotors would crack under stress. I wonder how they would hold on the track...

ummmmm that I wouldnt know lol. the hell with it. Try it and see!

I may have to do that! :D

Let me know if you want me to swap your rotors out. I have the PERFECT tool for the job homie.

will do man!

Mark,

If the rotors are drilled, they will be proned to cracking. Most aftermarket companies start with a blank and subsequently drill them. On the track, after a few heat cycles, they will crack. The exception to this rule is brembo (ie porsche) factory cross drilled rotors. Otherwise, I'd stick to slotted--heat escapes in a similar fashion as the drilled, but much less failure proned due to design.

Good luck.

BTW, you'll still be slow

Thanks for the advice Ben. But as long as you keep ripping body parts off the Radical, I will still beat you around the track. :D

lol! and nice info to know 'cause the drilled rotors look cool but i guess not good for daily driver cars. thanks beckertb!

I'm not disagreeing with beckertb cause I've researched and heard the same argument myself, but I've ran cross-drilled rotors on 3 cars I've owned and haven't had any problems. Although I've never track driven them. For those high heat and repetitive hard braking, I'd probably go with what the pros recommend.

I've had cross-drilled rotors on my 01 Jeep Grand Cherokee (notoriously crappy stock brakes), my current 06 Altima, and my current 05 Nissan Frontier.

yeah I think just daily driving on them will be ok. My car will see a road course every now and then so I dont know if it would be worth the risk. On my first weekend at the track a couple years back I boiled my brake fluid. Now I run Motul high temp and have not had a problem. :D

one of the guys i work with has ran slotted/cross drilled on his camaro and has went through a pair like nothing.

he says the best way to go is with big name brand blanks or just slotted......

i'm going with some 13" slotted for the Z and i've gotta get new pads.......
