Iv got a couple of ? one on the bulk head where the motor screws go for the gear mesh has anyone had the problem where the holes arnt the slitist bit big enough because depending on the gear but i run a 112 spur and when i gear between 7.00 and higher when i tighen the screws they grip the bulk head and move the motor/gear mesh. two I know the mi2ec generally has alot of slop but im getting castor slop and it seems that when I get in a sweeper i will find the lane i want early on but as the car progresses through it will change lanes and im pretty sure its because of the castor slop. what im working on right now to get rid of castor slop is im sanding down the c-hub where the hindge pin goes and im going to put a aluminum spacer inbetween the arm and the c-hub will this help prefent castor slop.
