I can get my hands on a set of B6 S4 brakes. Will these bolt up to my 2004 B6 A4 1.8t. It would be nice since they are free. Any btdt. What parts would I need to make it work. A search turned up no results.

I am tryingto avoid dumping a load of cash on the Brembo setup. If the S4 setup will not fit are there any other cost effective brake upgrades.

Thanks in advance.
