Update

My car has indeed scrubbed the insides off and the wisbone bushes look non-existent. The Wishbone is free to whack about from side to side. What a stupid design. At least i can use Cupra solid bushes, what the soultion is for everyone with anything below a 130 I don't know

I wouldn't recommend any wider than the tyres you have on there now, as the rim is suited to that tyre width.

I put some Goodyear F1's on there and thay may be good in the wet but thats about all, I have had them moved to the rears and gone back to the Michelins Primacy Sports that were on there whan I got it.
