I was looking at the AMS website today and it seems like they now offer light weight rotors for our cars from Girodisc. According to the site, the savings up front is about 11 lbs per corner and 8 lbs in the back.

Does anyone have these rotors installed? When I swapped out the stock wheels to some HRE's that saved about 8 lbs of unsprung weight, the car felt that it handled much lighter and the acceleration was more crisp. I wonder how an additional 8-11 lbs will feel. Does anyone have prior experience with Girodisc? Who will be the first to try?

According to RacingBrake, the stock 2-piece are 29 lbs.

Might not be worth 5lbs per rotor until you need new ones.

I'm definitely going aftermarket for pads and rotors when the times comes for replacement ... Will save $2000 over oem

Same here. I am leaning towards getting these rotors at replacement time. In the meantime, if someone decides to get them, please report on how they feel.

I drove past a grey e63s in the jewel parking lot on 95/59... Honked but no love ...lol

That sux! I met someone who literally lives less than 2 miles from me who bought an Alpha 7 E63 from AMS the other day. We took turns driving each other's car and I am itching to get the downpipes and exhaust as well. That car rumbles like an American muscle car.

Just went to check my rotors, and I think they are one piece. I may be wrong but if that's the case, a 10+ lbs saving per corner maybe a huge difference.

just bought 2 piece GiroDisc all around for my 211 wagon - haven't put them on yet, but looking at them in the box, they sure look pretty -

after all i have read and spoke to some other folks i am no longer a fan of RacingBrake - do some searching -

If anyone wants MBworld discounted pricing on GiroDisc rotors let me know.

They have parts for all non-ccb W212 E63 available.

Light weight yet for heavy track duty are RB two piece rotors:

Thats awesome but they dont make a or sell a more aggressive pad?

joseyu

I believe Renntech sells a brake kit with more aggressive pads as wells as stainless brake lines.

RacingBrake

We have different compounds for track application from medium to heavy duty tracking:
