Does anyone know if the 2004-2005 A8 rear caliper carrier will fit an UrQ with the 200 20v rear calipers to allow the use of 330mm rear rotors? If anyone else is running a bigger rear brake setup than the 200 20v/V8 set up I would love to know more. Please no emails about bigger rear brakes not being a huge improvement... Thanks.
