E55
I believe they do swap over BUT.....have you rpiced the E63 rotors over the stock E55 ones?You might very well change your mind when you do,or order some Evosport ones instead.

They are practicaly identical in all dimensions, but as J said, I'd consider the price and weight gains. They are only 5lbs (actually less) lighter than the OEM E55s. The EVOs are closer to 10 per corner.

Anyone know what the difference is with the Brembo GT kit vs. our stock setup on our E55, which are made by Brembo? Both are 8 pot, but the Brembo GT kit has larger 380mm rotors. Calipers any better? Curious if I could buy just the adapter off this kit to accommodate the larger 380mm rotors, that is if it's of any benefit.

Has anyone used evosport rotors? I would like to know how they stand up to the elements after some time. I just replaced my rotors and they already have some rust buildup.

The EVOSport rotors are fine. i like them lots. I paid $1500 for the 4 and save exactly 36lbs. I mated them to Porterfield pads and the only negative has been some squeeking at low speeds. Other than that, the heat, and grab has been a major improvement for the money.

Which Poterfield model did you get or do they only make one model for our cars. Hows the brake dust less than our OEM pads?

Awesome thanks for the answer. Been trying to figure that out awhile. $1500 for the EVOSport floating rotors, good price where did you get them at that price? I always see $2000 for them anywhere I look.

I got the rotors from a friend that bought them from EVO when they had their sale last year. The porterfield come in two compunds (street and track). I got the street version, since the track ones just don't work out on normal driving. The set costs about $500 and get them direct from porterfield. Brake dust is actually less than the oem pads, but I have noticed more squeeking after heat cycles. the squeeking is as you are slowing down to almost crawling speeds. A good hard run and they are quiet again for a bit. I honestly don't mind it. The bite on the setup is MUCH better and I haven't seen the overheating sign since (keep in mind I did not change brake fluid brand or composition, but did have the system flushed).

You are right in that the light pops on when the car calculates that heat is building, NOT at the wheels but at the rotors. Once the initial light comes on, you can continue ( I was told to by the AMG instructor and it wasn't my car, so hey). We did a few more laps and I felt slight, if any fade. Then the warning changed to say stop now. We took it into the parking lot and just coasted about for a bit and were right back at it. Either way, on an OEM E55 and some twisty roads, I can get that light on within 5 miles. I simply have not seen the light since I put on the rotors and pads. the squeeking is getting worse and I attribute it to the rotors more than the pads.

Jangy did you actually weigh them or did you go by what was stated?
also we deal in KG's here so any one know what the conversion would be in kilos?
also what it would work out to when driving, interims of weigh saving?
thanks

The difference in feel is huge, simply because it is not just weight, but unsprung weight. Every time you speed up, slow down, turn, or make any shift in momentum, that weight comes into play. Consider a gyroscope and see how much easier it is to manipulate when the weight is dropped.

The difference in feel is a crisper snap when you hit the pedal. It basically does not need as much effort to get better grip. Also, after some hard driving, the OEM setup would throw a heat sign up and the brakes would fade just a bit. I have had no fade at all with the Rotors and porterfield pads.
