Brake rotor question

Hi,

I'm thinking of fitting 4 pot rear calipers from either C63 or E55.
My question is, will the brake rotors from either C63 or E55 fit my W209?

Thanks.

I don't know the answer - hopefully someone with better knowledge will butt in.

Whatever you do, don't disturb the brake balance back to front. You need to maintain the back to front braking ratio as Benz designed. If you go up on the rear you need to correspondingly go up on the front or things could get ugly if you overbrake the rear & BAS, ABS tuning etc goes out of whack.

Thanks for your reply Glyn. Hopefully someone can chime in with an answer.

I have the 4 pot amg C32/C55/CLK55 front calipers so it should not mess up the braking ratio.

I am considering a 4/4 pot setup and go for 6/4 later on.
I recently bought the 4 pots with brand new OEM rotors and pads so I'll keep them for a while.

While I know the 4 pot calipers from C63 or E55 are not bolt on, I'm having them fitted by a specialist.

But I need to know if the C63 and/or E55 rear rotors will fit because they are included in the purchase, or if I have to purchase CLK63 rear rotors separately.
