I posted this question in one of the recent 'spacer help' threads but didn't get a response so apologies for asking another spacer question. I'm about to order some H&R Spacers but the company I am ordering through keeps sending me different part numbers. I am after 10mm front and 12mm rear. I think the rears should be: DR 24 3,18b,25 2455571 i'm confused about the fronts though. DR10 2055571A or DR10 2055571B A or B? The car is an MY10 S3 with OEM 18's. Thanks guys!
