Paul p-If the track temp is cool enough to run sorex 28's then you might be better off with the Hpi red insert. What type of surface do you run on? I can give you a very good basic set up for your wife's TC3 by PM because this is the Schuie thread and I could be killed (by Racer X) for posting info on another car....LOL
Racer X- I don't know what to do since the first carpet race has been cancelled. I guess I'll put in time for husband of the year this weekend.....
