Slotted and drilled rotors for street use are a bit silly unless you're doing it for looks. A good rotor needs to be cryogenically treated and then broken in properly to prevent warp.

I like Porterfield carbon / kevlar pads for their consistency under hard braking and their rapid heat dissipation. The only problem is that they will squeak like a school bus.

There's always a trade off...

 

This is really a simple DIY project, take a look at this web site, it should help:

There is a lot more on that site that could be helpful for Crossfires.

 

Bruce R. good info. We posted a DIY brake change on this site a couple of years ago, it's exactly the same process and should be floating around here somewhere. I also posted the DIY brake upgrade pictorial for the Limited to SRT6 spec. (slk320 to slk32)

 

HDDP, is this what your talking about? I was thinking I might do these as well sense I'm going to be doing the pads anyway. Is their really any better stopping power? And will these make any squeaking? I hate squeaking.

I have the first set of Porterfield R4S pads that were available for the SLK 32 ( I had to send a tracing to Porterfield so they could match them up), and I'm still running them... I get the occasional squeak, but never had a squeal from them. For track use you might want to consider the R4 pads, they require a little heat in them to start working properly, and are NOT recommended for the street. The R4S is a street version of the track only pads.

 

Well then I should thank you for the prototyping. I run the R4 pads. As you may know I upgraded my brakes to the SRT6 / SLK32 hardware last year.

 

Just put R1 concepts slotted and drilled rotors and Rotex gold pads on yesterday, and it was fairly straightforward... breaking them in easy and haven't stopped hard yet, but they are really smooth and linear on the uptake, and the rotors look GREAT. Don't be afraid to try this project...Thanks for the instructions!!

 

Last week I had disc-italia pads installed on front & rear at the same time I had new Hankooks installed. I was charged $140.00 just for the brakes..was told the rotors were fine. 29,300 miles on the car.
