Carpet dirties the tires less i think than outdoors but its a good idea to get in the habbit. i used to just re-apply my traction wash and let that clean the tires, but spraying a little brakleen on a paper towel and cleaning the crap off does help for sure. after a weekends racing you will note quite a lot of rubber build up on your tires.
for outdoors, if your track is sprayed they tires will definitely be filthy ha. clean them for best results.
not really that many tricks persay, just take your car appart between events and make sure nothing is broken/worn. clean your bearings and lightly oil them. make sure none of the bearings are being compressed by anything; axle/hex's compressing wheel bearings, layshaft being out of alignment ect ect. jilles has a youtube series about preparing your car that seems quite anal at first, but once you look at the car in such detail, it becomes apparent in the results. a faster, easier to drive car.
