Im running green in front and white in the rear, I think it is just a matter of adjusting my driving style, my Durango does not have much initial steering, so its quite a bit to get used to. Yesterday was only my 2nd time racing the 4.2 and have really had no real practice time on it. The car feels much faster than my Durango, and I have turned considerably faster laps with the 4.2, but my consistancy is horrible right now haha.
