BMW Braking Advantage - why?

[rscheiring]

I was watching a tape of the Rolex series race last night, with the PTG M3 outbreaking every car on the track, Porches and DP cars alike. So, why is that? I'm thinking it isn't rotor size, and I doubt its weight. Is that car just that much better balanced and set up?

One of BMW's "motto's": The brakes and suspension must be faster than the car.

What would you rather race...

A. a car with gobs of horsepower and decent suspension & brakes

or...

B. a car that has good power with confidence-inspiring suspension & brakes

I would prefer the latter. To coin a Pirelli Tire ad..."Power Is Nothing Without Control."

It may have to do with the caliper placement. BMW's have the calipers mounted on the Trailing edge of the rotor where as most cars on the road have the calipers mounted on the Leading edge.

What difference does that make, on a circular brake disc rotor?

I'm asking - not criticizing or calling BS.

When you apply the brakes the caliper will push against the suspension on a bmw, where as with another car when you hit the brakes the momentum of the wheel will pull the suspension cuasing the car to nose dive slightly. I can tell the difference from hitting the brakes on my car and my mom's toyota, here car just dives when you hit the brakes.

perhaps it has something to do with the cycle of weight penalties.....maybe the m3s were light that day? i dunno, does Rolex even use weight penalties?

Weight is certainly a tool/weapon/penalty of Speed GT --- remember the boys (Auberlen, Said, Stuck, Marks and Miller) racing for Team PTG last year with 150lbs of ballast?
