olu Posted July 7 Share Posted July 7 Hi everyone, I need advice on upgrading my A6 Avant C8. I'm looking to replace my 20-inch alloy wheels (255/40 R20 Y XL) with 21-inch wheels. The alloy wheel company suggested RS6 21-inch wheels with an ET35 offset and a 5mm spacer to clear the brakes. However, both Audi and some other sources advised against the ET35 offset. When I went back to the alloy wheel company, they recommended an ET30 fitment instead. For reference, my current 20-inch wheels are labeled E8.5J×20 H2 ET43. I'm also planning to upgrade my brake discs and calipers to a larger size, aiming for an RS6-like appearance. Can anyone advise on the appropriate size for the brakes and calipers? Has anyone done this upgrade? If so, what size did you choose? Quote Link to comment Share on other sites More sharing options...
