That would take some abuse, now the SLK32 setup is insane on a car barely tipping 3K. A guy who autoXs with us in a M Coupe (highly modified) said my car stops quite a bit better than his (3600lbs) that brought a smile to my face
John have you done anything with the brakes yet?
I am trying (desperately) to get on your
level with the suspension (pun intended
)
All I've done on brakes so far is in the sig... Akebono pads and the ATE super-blue fluid... DOT5 is a bit iffy in some applications... DOT4 should be all you need. FWIW, the only cars that we fill with DOT5 at Nissan Motorsports are the full-blown track queens... If you cook DOT4 in a street car, you're relying on the middle pedal too much.
As for the suspension, the cut AMG springs will bring a smile to your face. I still wake up at night sometimes wondering what life would be like with Vogtland springs, but then I am quickly reminded that the SRT/AMG springs are indeed competent.
I will be going with the C32 setup eventually, simply for weight savings and aesthetics. If it stops too suddenly, I won't press as hard next time.
The racing-brake rotors (340mm only) are 17 pounds... the 330mm rotors are 26 pounds each (300mm rotors are 25#). Couple that with my new wheels and that's a 13 pound savings
per corner in rotational mass on the front end. The aluminum C32 calipers are ~30% lighter than comparable steel two-piece ones... a nice drop in unsprung weight. Hello curves
