The gears really depend on your tire height. I am at most gonna run a 3.55 may stick with the 3.40s I got. I have 24.5 inch tall tires. It rpmed fine eith the 26 inch tall mickey thompsons. Throw in the TKO600(close ratio) and it should all be good. You should also consider open track or a road race course. Differemnt gear selection for sure.
