Iv got an 08 plate S3 running stage 2+. The brake pads and disks are about shot, and could do with changed. I was thinking now would be an ideal time to change the brakes to something new. I was just wondering what options i have, and what is the best course of action. I have read that you can fit RS4 brakes to the S3, but is it actually worth the money for the gain, or would i be best just upgrading the brake pads, disks and getting some braided brake lines?
