I read somewhere today that reducing rotational mass can help. Reduces a wheels tendency to bounce apparently. That means light weight wheels may help. There are other good reasons to have light weight wheels too, but that's for another thread probably. A wheel that's 4kg lighter may have a positive impact. OZ Alleggerita are my choice at present. I have s3 lower arms With WALK but the front bush is still OE. These arms were bought new so the front bush is new but probably not as effective as the WALK bushing at restraining the arm under heavy load. I'm feeling that I may get it changed for a poly bush of one sort or another shortly.
Interestingly I am also running Goodyear F1's
