Sorry if this thread has been posted already. Have looked for ages to find one! I have an A3 Quattro, Will be lowering it on S3 H&R cups (25mm drop for S3, 35mm for my S line) and H&R ARB's. What are the best size spacers front and rear to fit without any rubs at all. I've heard 10mm front 12mm rear and then seen lots of 15mm rear.. I really dont want any rubbing. I do occasionally have people in the back of the car but only 2. The ET of my current wheels are ET54. Cheers guys and girls!
