Default Wavy disc brakes
What are the advantages of wavy edged discs? Anyone ever use a set on a car?

Thanks!

I think it is supposed to be slightly more surface area for cooling, or maybe just for looks...

Probably the same advantage as the holes drilled in them.

seriously? What's an rs7 weigh? That seems dubious to put those things on a large, powerful sedan.

RS5 had them, too. Seems like a fairly inexpensive way to reduce weight in an important area, while looking cool to the customer.

braking isn't important? they're saving what, 5 pounds total? Inexpensive way in a car with a $110,000 base price?
I'd look for weight saving in a 4500-pound car else where.
I don't think it's for weight saving.

BBK will loose some unsprung weight. Carbon/aluminum driveshaft and axles for rotational mass. Also a set of rpf1( one of the lightest). About those rotors..... I have seen them. Never seen them on track. Don't know much about them.
