Hi. I am looks into convert my front track width using parts from an RS3 8p. Can some one help me with one question and maybe Parton. ? I am currently using S3 front alloy swiveling arms/hubs. Question. Is it only the front bearing and hub that is different? The reason: I wish to upgrade to RS3/TTRS brake setup using the RS3 disc. This moves the caliper away from the wheel eliminating the use of spacer. It'll also widen my front tracks a bit depending on my wheels used for this setup. Did anyone here tried to do this on a none RS car?
