FC Brake Rotor Size Question
Does anyone know or can access their rotors? I ordered some rotors and they sent me the wrong ones and now I need to know how wide and big they are(I don't trust my super rusty ones). The car is a 1990 with non turbo brakes. Thanks in advance!

there are two types of five lug brakes.
Vented rotors and SOLID rotors.
Only other setup is the 4 lug Rotors,which really do not apply to the s5.,

should be vented all the way round.
4 piston brakes (front) use the vented rotor..back uses the same.
Single piston fronts have the solid disc as well as the back.
If you have BOTH then some modifications were made or someone goofed.
Look at RockAuto Parts Catalog and find your setup and application.

Thats weird. I order slotted and drilled rotors and pads for my 7 from rock auro and the rears are too big and im going to check if the fronts work on the weekend. What type of brakes should non-turbo fc's have all around?
