Mahle 4 bolt weight Options

[Tobra]

Howmuch does a Mahel 4 bolt wheel weigh, apparently the Fuchs 2.0 liter is about 11 pounds, which is pretty darn light. Just curious, low unsprung weight is always a good thing

...I bet slotted rotor with aggressive pads and BMW calipers would stop a ton of motor.

they will, but they won't do it very many times before they boil the fluid -- they cover a lot of the disk that was used to radiate heat before you mounted big calipers...

fundamentally you're right.

but you need to evaluate the intended use.

if you take the "low unsprung weight" setup to the hot lap day on the big track you'll overheat the brakes. if you take the "endurance-racing short track" setup to an AX, you'll be giving away pounds of unsprung weight to the dedicated AX cars (which is why it's hard enough to have a dual-purpose -- AX/street or street/DE car, and trying to do them all with the same setup leads to many unpleasant compromises).

compare a NASCAR short-track brake setup to their Talladega setup -- or an Indy car's street-course setup to their Indy 500 setup. for the ovals they use brakes that look puny on motorcycles. for short tracks they're fricken' enormous.
