cross-drilled rotors - pad wear

[RandallNeighbour]

When I have to replace my rotors, I was considering the installation of zimmerman cross drilled rotors. But, I heard the slotted ones rip up your pads quickly. Is this the same case for the cross-drilled variety?

I am also thinking of doing this. I put cross drilled and slotted rotors on my truck along with Hawk pads, and the pads are wearing just fine. Could be that I'm using a quality pad that my wear has been good.

Cross drilled / Slotted rotors with red calipers would look outstanding. :dance:

I've never heard of box S pads wearing more quickly than the standard boxsters so I would think the answer would be no.

I've just made the change to x-drilled discs, ss braided lines, ATE racing blue fluid and EBC green stuff pads on my '98 and although I'ts too early to talk about wear I can attest the difference is significant....the car stops much more solid and firm and reduces speed faster without activating ABS. The added safety for me makes it worth the probable increased pad wear I may get.

Your choice of rotors depends on whether you're looking for performance or show. Slotted rotors will cool a bit better but will bite your pads a bit more and so wear them faster. This is a good thing if you're running at the track, but will increase your pad change interval. Drilled rotors look cool, probably cool better than slotted, but are more subject to failure. I'd use these for a street driven car that you want to look cool.

For pads, I love the EBC greens for street use - they don't dust or squeak, stop very well, and are way cheaper than stock pads. However, if you take them to the track you will melt down a complete set in (and I'm not exaggerating) 15 minutes. For track use I tend to run EBC Yellows for the front and greens on the rear - The yellows stand up to the heat for a complete track day and greens on the rear will add a bit of rearward brake bias and are OK to run since the rears don't heat up that much.

Cross drilled are made for everyday use, and provide less glazing and cooler operation of the brakes. The slotted rotors are designed for the racetrack. There entire reason for development was to give the driver a consistantly renewed braking surface on the pads. These slots were designed to shave a miniscule amount of surface off of the pads each pass to prevent glazing and decreased performance. The fact is that if they are true slotted rotors you will see a quicker rate of pad wear, but some people like the looks of them and put up with this. To each their own. I like the looks of the cross drilled/slotted rotors, but am going to go with the cross drilled only myself.
