Im guessing but could be wrong that the mk6 has the same front bottom arms as the mk5 and that GTI engineering still do the modified ones to increase the negative camber?
No, it appears not the same arms...Didn't SteveP try to fit a Whiteline anti-lift kit (WALK) and it didn't go?
Mk5 has alloy bottom arms doesn't it?
Steel on the Mk6...and obviously slight geometry tweaks.
Not sure as you say they are prob different.
Im sure our mk5 had steel arms. I know the TT has alloy, i think the S3 does too.
