Picked up my new car on 29 March and didn't like the runflat tyres fitted to the 326 wheels so tried some 18" APEX wheels with non-runflats and liked the smoother, quieter ride but the rear offset of 22mm was a little too aggressive. So, I've now fitted a set of 313 wheels with Goodyear Eagle F1 AS2 tyres, 19/8.0 ET37 235/35 fronts & 19/9.0 ET39 265/30 rears and hope that this will be the answer! They probably suit the car a little more than the APEX's too!
