Hey guys. I plan on running the car in two different classes. Stock (17.5 boosted) for club meets and 21.5 (blinky) for a different championship. I'm concerned about the gear ratio though as for the blinky I might need to go as low as 2.8/3.0 FDR, this is going to mean something like 45t pinion and 66t spur... would that even fit on an XI?
