XRAY - Model racing cars

I do have 2 tight sections on the track, a back to back to back 180, and then a short run to a large double follow by a short run to large single onto a table top. I am just a bit worried about losing top end on the big straight in front of the drivers stand. That is why I was wondering if it made a difference in the way it handle because I know if it does I can make it up easily on the rest of the track. Here is a link to the track I race at. http://www.pbase.com/damin69/rumble_2007

If you have a decent high rev .21 I wouldn't worry about the straights. I never seen a whole lot of races won on straights, its mostly suspention and cornering.

If you want it more aggresive bump up the center diff oil to 15 or 20.
