Default B5 A4 Brake upgrade......

I have a 01' A4 2.8 Quattro Sedan and am looking to upgrade the brakes. I know about the A8 option bud what other options do I have?

Can I fit S4 front Brakes without using the entire knuckle?

I think you have the same uprights and brake line connections but you should double check. You will need the rotors, carriers and calipers and pads.

B5 S4 brakes unfortunately don't fit the uprights on the A4.
There aren't any OE upgrades that bolt on with a larger rotor other than the "A8" 312mm kits.

Our Stage2 simply adds to that the Boxster calipers making for a nice complete kit.

B5A4 and B5S4's have different bolt spacing for the caliper mounts.
