    Me, too, although I am having a bit of drama with the 235-40/18 fronts on 18x8s. Rolling radius is correct according to my calcs, and it looks fine, but under more "spirited" conditions I have caught the inside lip of the fenders and they have bent.

    Will be having that sorted (hopefully with v. minimal paintwork) and maybe half a crank on the suspension JIC. Cheezes me off slightly but these things happen. Still looks better than the stockers, I reckon.

    Cheers

    Kevin, I did the same thing with my front fender. I went back to 225/40/18. No more problems..

    Maybe 235/38/18 will work OK... Not to sure though..

    The 225/40/18 wear perfect on the tyre when doing trackdays...

    The 225/40/18 are great, standard on the 355. When doing track days the car did not understeer and the tyres wear was even across the whole tyre. I traid spacers on the front with 225/40/18 and damaged my front fender slightly, but upset the front handling because the wheels with spacers on front where in line with edge of the fender edge. no good.

    Gone back to no spacers on the front with 225/40/18.... Great....

    I have 18" 348/355 Challenge wheels with:

    225/40s up front and 285/35s in the rear. This set up made a HUGE difference in the handling. The extra rubber and the decrease in unsprung weight from the race wheels makes the handling come alive!

    ...and don't forget to addsome big Brembo's

    Ciao
