I have drilled and slotted stoptech rotors in mine, with Stillen brand pads at all four corners, factory sizes. No complaints, easy to install, decent amount of brake dust but that's to be expected from performance pads. I was looking to go with the EBC yellow stuff pads but Stillen had a deal where the pads came free with the purchase of rotors.
I just ordered a new set of rotors for my car, they are Stoptech Cross drilled&Slotted rotors. I'll post my experiences here when I get them installed. I also got Stoptech brake pads. All original size (no upgraded sizing) to my SLK32 AMG.
Interesting fact that I learned: Stoptech doesn't "manufcture" the rotors, they only drill holes and slot the OEM ones, then paint the hats/fins for those models that have that feature.
That is interesting. From looking at their website you would think they make everything. I'll stick with Akebono pads for now as they are priced nicely and I've had good luck with them on my BMW X5. We put the rear rotors on the other day. So far so good. We'll do the fronts probably by the end of the year. Thanks for the input.
