If the track is wet enough to throw "rooster tails" off the tires I would suggest using:
- 75mm front hubs with at least 2 thick spacers wide - 1.5 degree to 3 degree caster - 5mm toe out - 5mm positive camber - no front bar - B axle - short hubs with the hubs set 1/4" in off the end of the axle - Normally we use the Freeline cast aluminum wheels. As the track starts to dry out you can run more of a dry set up with the rain tires on.

When the track is very wet I have found success using:
- 1 degree pills top and bottom to create up to 1cm (10mm) positive camber while the rest of the adjustment in the pills is used to add caster - Seat struts on or off will depend on the amount of water on the track and the speed of the turns - Very Wet and slow corners with the struts off, slightly wet and fast corners with the struts on - I have also found success with softer axles to help in the slow corners and long hubs to add side bite in the fast corners.
