Mine lasted for a few runs at the MK GP but then stripped the gears in the rear on my TQ run... LOL
(haven't opened them up yet...).
Just got new gear sets in the post so i'll rebuild them soon, the question is: last time I used 1 extra shim on one side as it felt notchy with 1 each side. How many shims have you guys been trying? Do they need the extra shims to make it super tight?
