brake dimension

[RS4inGermany]

I am going to upgrade the brakes on my B5 RS4. I am trying to determine the rotor dimension for the front and rear rotors on the B7 RS4.

I have searched through the brake upgrade threads on both the B5 & B7 forums and I'm unable to locate the dimensions. In the B5 sitcky it lists the rotor's OD (front) @ 360 mm and the (rear) @ 312 mm.

Stock B5 RS4 (F) 360x34(?) (R) 312x10(?)
Stock B7 RS4 (F) 362x34(?) (R) 324x10(?)

I am considering either the B7 setup, or the AP Racing (F) 365x34mm (R) 343x(?), or the Alcon setup (F) 370x32 (R) 310x28mm.

The Alcon set has new rotors front and rear. THe Alcon set uses new calipers in the front but the stock caliper in the rear.

thanks for the info on the B7 brakes. I have read what people think of the AP Racing brakes. Do you have any opinion on the Alcon brakes? Seems some think upgrading the rear brakes is a waste of money. Since the Alcon brakes just upgrade the rotor (more for looks I suppose) this seems like the better route although, I have not read that much good, or, bad regarding their brakes.

I'll be honest, I really don't know. I have a B7 so just knew the measurements

You might get a better answer if you post the question in the B5 RS4 section:
