I should add that there is a set of BBS CH 19" rims and a set of Falken FK452 tyres in the back too, which is not helping the rubbing.
I have a set of 225/40 and 255/35 tyres next week, this will sort it out a treat, don't think I will need the arches rolling at all with those tyres fitted.
Having said that, at the moment the ride is sublime, so I may roll the arches and keep the oversized tyres on the car. Speedo is now bang on the money too with the incorrect tyres on there.
