In Reply to: Slotted or X-drilled? best rotor for the E-30 M3.. posted by Highrever on May 29, 2002 at 17:10:19:

x-drilled are less expensive but older technology that can crack under hard load. Slotted are about $100 more expensive for a set of 4 but I understand that they resist warping a little better than x-drilled and are obviously not affected by the cracking problem. I am due for replacement soon as well and I will be going with slotted all the way around.

Some folks say it is best not to replace rotors and pads at the same time as it prevents proper "break in". This may be true if you're preparing for a race, but most likely unnecessary for street use. Just thought I'd throw that out there.

Best of luck.

Looking into doing a 4 corner rotor replacement. Stock just won't do, and don't want to spend the 2g's for Brembo's, So i'm looking into X-drilled or slotted + pads for street use. Any suggestions? testimonies? I'm leaning toward gas slotted and some good street pads, but your input is welcome. Thanks
