We just had to do this last week on our car. What we did is, we set up everything for a fast three wheel car and then on the NDFW we bent that axle just about a half a degree and was able to make the wheel just barely touch on a perfectly flat surface with the hopes of a not so perfect track and it worked like a charm. It had no affect on the cars steer and we won big time. Oh and we graphited the part of the NDRW that touched the track in hopes of sliding instead of rolling. Best of luck to ya!
