28 will drop your end gear ratio making a 3.55 like a 3.31 or 3.27, the 26 let's you keep that 3.55. So basically it adjusts your gearing. Have you been to the track with this setup b4? If you have wat gear were u in at wat rpm at the finish?
I haven't been in this car yet. I am leaning towards a 26" tall tire (16" wheel). I just can't decide if I should go bias ply while keeping my radial nt05's up front....I have always read and been told not to mix....but it appears that the guys that actually race a lot do it all the time.....:shrug:
