Has anyone tried to fit floating 360mm rotors (intended to be used in 63 - 6piston calipers), in 55 - 8piston caliper?

The hat is the same, and diameter is the same 360mm, I am wondering about offset and thickness of rotor mirror

My usage pattern has warped several sets (no binding can be detected in brakes, I just overuse the crap out of them) and hoping floating rotors will yield less vibration, without having to replace calipers...

If I do need replace calipers, I might as well go 19" wheels, and 030 brakes...

These are the rotors I am hoping to fit on SL55

Same hub, hat height is close enough...go for it.

Kyle,

Small world!!! The whole idea came about while checking out your stock, after you announced your sale yesterday

Just found a thread showing this being actually done...

So your question has been addressed.

Sub'd to see if this actually works. I'd like to do the same thing if it flies...

I ll keep you posted

Best place to go check is racingbrake.com. The fitment guides will address your question.

Thanks for the referral Jon,

We can confirm Our P/N 2141 (360x36mm) two piece rotors will also fit E55, E63, CLS55 and quite a few other applications.

Rotors are in stock, ready for shipment.

So now we all know that e63 rotors will in fact work on a E55. But will an E55 rotor work on a E63? For those that don't want to spend close to $2K just for the front rotors.

You dont want to do that, even if possible, Trust me

There are one piece alternatives for 63, but they will warp like crazy, and increase the rotating mass significantly... I am going the opposite direction to get rid of the solid rotors...

Not to mention solid rotors are about 400, and floaters are 750 for pair, so not exactly a 401K depleting investment...

No, it's not for me. I was just curious to know if it was reverse compatible. I've just purchased a complete brake kit to include two-piece front rotors, rear rotors, pads, sensors and brake paste.

Short answer is yes, they are dimensionally (sp?) identical, as are C63 one piece units. The primary difference with the C63 one piece rotors are the two set screw holes vs one hole on the E55 single piece rotors.

Sooo, the 2 piece Brembo rotors on eBay from above WILL work in an E55? With or without modification?

Yuille36

The short answer is yes, they will work.
