Drilled/Cross Drilled Rotors...

they will look cool I guess but crossdrilling is only a looks thing. I woudl personally just get zinc washed slotted rotors if looks is a concern I have never ran crossdrilled because I have just heard that if you overheat them they can crack. I am not going to pay extra for an option that makes the rotor inferior. I am sure it is directly related to where you buy the rotors from though.
 
I replaced my original rotors with slotted rotors. They worked fine, no problems at all.. only when it came time to have them 'turned', most shops wouldn't touch them, the only two that would, wanted to charge me $50 each for fear of breaking the blades on their machine... :notnice:
 
I'll have to disagree with the "nay" sayers...The difference in performance is very noticeable in regards to heat disappation and stopping power, effort is less and fade is near zero. If your looking for performance, go for it...If your looking for "looks" save your money. Here's mine with CHROME BULLITTS http://groups.msn.com/1998redmustanggt46/my98mustanggt.msnw?action=ShowPhoto&PhotoID=168

Brake pad wear is normal but I would suggest a high quality pad like HAWK HPS pads for the street. EXPERIENCE talking...
 
I disagree. I have some on my Cougar and they were the best investment. I did 6 100MPH to 0MPH stops and only on the 6th one did I have virtually complete fade. I also had carbon fiber pads. I replaced the pads @ 50k miles and turned the rotors. I still have the rotors and some cheapo pads. The cheap pads suck :)
 
Kind of a stupid question but does anyone know if the slots should angle TOWARDs the direction of rotation, way from the direction, or doesnt matter? I have drilled/slotted rotors and Hawk pads and noticed that I put them all on (totally without thinking) where the slots are opposite the direction of travel. Just put them on and breaking them in so if they need to go the other way, want to do it pretty soon.

Depends on the brand, the venting on the inside of the rotor is what counts. On Brembos, when the vehicle is in forward motion, the pad is supposed to hit the outer end of the slot first. I have been told that Powerslots are the opposite.

I have brembo slotted and drilled rotors and Hawk pads, i have had no problems yet.

And you probably will never have a problem. Not enough heat generated on the street. They do have the looks factor.

On a road course it is a whole different story. If you ever end up doing that then prepare for cracking between each of those little holes. I've seen it on EVERY brand of rotor, including those new composite rotors from Porsche. Yes, you see drilled rotors on those F1 cars, they replace them every race/ practice session. I can't afford that, slotted not drilled for me.

Thanks for replies has anyone run them on the 03 wheels if so how do they look?
18x9 afs 03 cobra's with cobra brake kit which comes with a great quality brembo 13" rotor.

Don't waste the money on drilled rotors, the brembo's don't get too hot and are really strong, along with more surface area than drilled ones.. drilled rotors are prime candidates for cracks and warping.

check www.tirerack.com for the brembo replacement rotor.. Otherwise Powerslot rotors if you want something with some looks.
If you don't have new calipers yet, don't waste money on new rotors, just get the cobra front brake kit like i have for 399 from www.mustangparts.com
