I run 295 or 305's up front, I get better turn-in response in my GenII.
Go with the 295 , for better turn in and less push as Leslie brought up. Keep in mind that the 295 is the standard size for the front tire on an ACR........so no sweat!
Wow that is it for sure! I had so much push, I felt a big difference with the 295.
GenIII, I have track friends that run wider tires up front too.
I have a gen 2 and run 345 x 35 x 18.
