Seems strange to me not to have seperate left and right side rotors in the front to provide effective cooling.

This was also done on the Corvette Z06 which really doesn't surprise me (from GM). It does surprise me on an Audi though.

The vents in the rotors are shapped to push air out and therefore you need a left and a right. On all cars, 80%-90% of the braking is done by the front wheels so they are put under the most stress. Temperatures in the rear brakes just don't get high enough to warrant the vents being shapped like for the front so they are just straight so you don't need a left and a right. Many manufacturers do't bother even with left and right for the front as the brakes don'e get hot even in every day driving anyway.

This isn't my first time to the rodeo lol.

What I'm saying is my car (maybe all of them I don't know) have directional vented rotors on the REAR (ie: the vents run in the correct directions on both sides) and the front hase what most would consider to be RIGHT side vents with the left corner flowing the opposite of normal.

impeller they have a bunch of stalagmite /stalactite looking things that somehow pump out no matter which way they are spun. Don't know exactly how they work and don't know if the RS4 has them just throwing the idea out.

Sorry, misread your posting. That it pretty strange.

There was a post about this several weeks ago. I agree that it seems strange
