Some of you may know I converted my n/a Crossfire brakes to SRT rotors with CL500 MB/Brembo rotors. Factory SRT/SLK32 OEM rotors only come plain and I wanted a little more bling and went with Disc Italia wihch I am not pleased with. They are somewhat noisy and they used just left rotors to drill and slot. the cooling vanes are going the wrong way on the right side. I am referring to the internal vents and not the sloting.

I spotted a 2006 E350 Sport today and the rotors are factory drilled like the C32's and looked about the right size. I just checked the brembo engineering site and they seem to be almost identical to the SRT rotor. The only difference is overall thicknes (top of hub to back of rotor) is 1mm thicker.

I have to go to the MB dealer to get a few parts for the V8 project and will compare these rotors to an Extra SRT rotor I have.

 

if im reading this right you have the slk32 rotors on the car. the fronts are 330mm and the rears are 300mm the c32 fronts are 345mm and the rears are 300mm hope this helps in some small way

 

Lantana, the C32's I just put on are both right side rotors. The SRT rotors are also both the same side. I put Power Disk slotted on the Aero and they came in left and right and are very nice, and quiet. I hope the C32 drilled rotors aren't noisey......

 

I am very familiar with the rotor sizes as I was the one who started the thread C32 brake upgrade. I think you you guys didn't understand what I was saying above. While I started the C32 thread, I acutally ended up with 330mm rotors becuase C32 calipers are very expensive and S/CL class use the same Brembo caliper and are much cheaper to buy as they are much more plentiful. The only thing I didn't like about this set up is the OEM SRT/SLK32 rotors are not drilled like the C32. What I was pointing out is that OEM C350 sport's use a factory drilled rotor that looks like it will fit my set up or anyone with a SRT.

 

My only point was that the SRT and the C32 rotors that I have seen are not left and right sides; but both the same, left OR right side. So MB may not be paying too much attention to their directional rotors.......

 

Got it. When I bought my CL500 calipers for only $150 they came with the factory drilled rotors (not useable on a Crossfire) which were diredtional left and right. It might be when they get replaced they don't pay attention to that. It is hard to believe that Mercedes would design directional rotors and then put two lefts or two rights on a car. I will check on this when I am at the dealer. I am thinking of OEM rotors becuase I like the way the OEM drilled rotors look and I know they are quiet. I have tried OEM, semi metallic and ceramic on the Disc Italia's and the ceramics were the quietest but I am still getting a squeal just before I come to a complete stop.

 

Lantana,

Did you look at the SP performance drilled and slotted zinc plated rotors? I am ordering them tomorrow. They are very similar to nickel plated in appearance and look very nice. They are about $298 for the front and $272 for the rear for the SRT.

 

I am familiar with SP rotors and they do look good. I don't hve SRT brakes in the rear yet but am trying to find some rear SRT calipers.

 

I have rear SRT calipers if you want to buy them off me! PM me.

 

Have you heard anything bad about them? They seem to be a quality piece.
