Quick question for those in the know.
Will the standard S3 17" wheels fit with Cupra R Brembo's on?
Yup, they will fit behind the OE 17" Avus rims, it's to do with the shape of the spokes and how they clear the Brake Calipers. The Avus rums have flat spokes at the edge of the wheels, so plenty of room for Big Brakes. The RSTT's have dished spokes which go inwards slightly nearer the centre, so they need spacers.
tight, but yes!
