What tyres?
Hark said:I'd imagine those would feel planted in any size.

And the Z4M has a bad habit to understeer a bit

Much better grip and high speed stability compared with the standard Conti's but more tramlining on worn roads due to the stiffer sidewall. No rubbing at any point, but the fronts are very close to the wheel arch liner at full lock.
Several autocross sessions, 1 track session, spirited driving on the road, diagonal crossing of sleeping policemen.ga41 said:aerobod said:245/40-18 front, 275/35-18 rear Dunlop Direzza Sport Z1 Star Spec on my car (standard wheels).

No rubbing at all?? What sort of driving have you tried them in?
Hark said:Ideally was going to run 265/30, but 275 might fill the rear arches a bit more? + Wider rears look nice.
Heard one person say the high speed handling felt compromised though?
Thoughts? Anyone use the sizes?
