thanks for the responces gaz8 and raving-monkey.
gaz , so are you saying i should get the 3 racing hinge pins or the ae ones. i have the rpm ball cups and a wide nitro tc3 setup as the bumper with the rpm plastic thingy on the bottom. i would like to get the p dub bumper to bullet proof my ride tho.
i have the irs alum diffs for a tc3 but they are shot
i was gonna try to get the speedway pal ones but ill probably end up gettting the lightened steel ones thanks again guys
P.S. has anybody tried those aluminum rear hubs by square or 3racing (not sure witch one makes them) and are they any good, are they lighter?
