Thanks for the reply guys, Jimmy what gear ratio did you have in mind for the 7.5 looking at 9.0/28.0 for rear tire and also the 2.75 or 2.92 first gear with the C-4. Tire is the radial. Now trying to figure out the ECU piggyback for the injection. I have pretty much got what I want for. the motor combo and suspension. Am I right that I need to tie frames and don't need a rollbar or has that changed?
