ok cheers, I havnt run it yet so will try it first and see what its like and to compare when i do make the upgrades. I have put the alloy tlr 15deg casters on it tho during box build and also included during the build is an alloy tlr top steering plate, tlr alloy rear diff inserts, strc alloy front mount for centre diff, i also built the diffs with the xray washer as suggested, all oils are stock wts too except rear diff i put 2k in it as our track generally has quite a few hairpins and tighter techy stuff....will see how she goes
