Today I put the summer alloys on (two new Falken 914's front and old Conti's SC2 on the rear) and the roll seems to have stopped, I'm thinking it was the rear Hankook V12's sidewall on the 16's that was flopping giving a weird roll/ sway motion as I did a suspension bounce test (fine) ran it over uneven road surfaces (fine) yet it was flopping (best description) on corners and large road cambers. Still going to replace the shocks in the near future (and brake discs, brake lines, arb bushes..my god the list is endless...god damn you Mercedes...my 8 year old Citroen needed nothing in 4 years bar tyres and drop links!!!).
