Discs won't but the calipers will
3 main options...Use the TTRS disc as the RS3 won’t fit easily due to a different offset. However from what I have read both discs are expensive to replace and widely considered pretty pants!Buy a DaveB fitting kit to allow you to run the TTRS/RS3/Aston 4 Pot caliper on a 340/345mm disc as I have done.Finally the ultimate option a floating rotor setup… If I remember correctly DaveB sells a 362mm kit and Alex sells a 370mm kit
