Had a super fun race with a fast young gun last night! Overall I much prefer racing dirt than I ever did carpet. Tekno's just love racing on a blown on track surface lol.
Biggest setup differences from carpet -
10/15/7 diff oils
18/19 ride height
Red front springs / Orange rear
Ended up going with VP Pro TurboTrax tires in soft. (same tires I run for ebuggy) and they seemed to work well in the dry and the wet.
