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
I would love to get some more info on the DOT5 being iffy? Every single track car I have ever been around has had DOT5, the only issues I am aware of is that you must COMPLETELY flush the 3 or 4 before doing 5, they DO NOT mix, other than that, I am unaware of any issues.
Do you intend on doing any proper track racing or just Dragon type stuff? If you say cooking DOT4 is relying on the middle pedal too much, you have never been on a tight autoX course (we had an M coupe cook his brakes last weekend with factory DOT4). I have really pushed it at the Dragon and on a track, it is night and day difference (at least our courses are)
C32 calipers, light weight wheels, modified suspension... and
all season tires, am I missing something here?
