My S3 Sedan came with the C0J 8J x 18" 5 parallel spoke wheels, since I don't have magnetic ride and the road here in Hong Kong is extremely bad, I really don't want to go up to 19"... I really like the look of the 19" C6H 5 twin spoke star on the Sedan and the Sportback has a standard 18" of the same design?
For whatever reason, the 18" on the Sedan is 8J ET46 vs Sportback's 18" which is 7.5J ET51? If I somehow go locate the SB 18" for my Sedan, running the same 225/40-18, does that mean by calculation, the wheels would be about 1cm more retracted than my standard 18"?? Anyone done this here?
Or if I go with 19" and drop down couple psi (39/35 on the 18" cold), good or bad idea?
