I will say, the AR5 doesn't like heat. We broke one in the Lemons B210 last year. The shifter gets stiff as the transmission gets hot and one of the drivers broke the 3-4 shift fork which is apparently very thin aluminum. If you are going to beat on it, Drift Motion has a billet shift fork and another Lemons racer recommended an oil pump and cooler to keep the temps under control.
