I have 255/40 x4 now and for my next setup I'm leaning toward a 245F and 255R. I go to about 5-8 HPDE events a year with the rest daily and I really dont like how tall a 255 is up front. (When I buy a daily I wont care as much I'll go back to 255x4). My question is will it be relatively easy to dial out the inherent slight understeer this setup would bring? I want to be neutral to minimum oversteer. I would also assume that, with a 245/40 and the narrower sidewall, responsiveness and turn-in would be a little crisper than a 255/40. In terms of ultimate grip there would obviously be a slight reduction but with only 4% less less tire surface area it shouldnt be much. I dont ever plan on racing competatively. More concerned with the "fun-factor" than setting record lap times.

Does anyone have any experience with this setup or like to give me their thoughts? Much appreciated.

 

That's not going to amount to much difference. I wouldn't change anything other than *maybe* a bit more front camber if it's available to you.

 

Yeah that's kind of what I figured. I still have increased front grip reletive to the rear compared to stock. Anyone else have experience tracking with this setup?
