Priobe,

The fronts all depend on clearances. On the SPF cars at full lock either direction they would rub a bit on the front frame rail but this was at lock and not a problem. Only place you get there is in parking lots.

An E-M is probably different.

Factory Fives have similar issues but few actually care or will put travel limiters on the steering rack, not my idea of a good plan. But many FFR guys run 245/255.

Never had a driving/wandering issue attributed to the 275 width other than there was little or no understeer at speed.

I wouldn't consider less than 275 and a FFR friend was running 315s in the front but he was big into autocross.

Tires are the only thing holding your cheeks to the ground. Make wise selections.

PM for more. I'm happy to talk.

Jim
