Thanks both of you for your responses, I really needed some guidance. I know the bearings that came in the Inferno GT2 aren't quite up to par so that is one of the last things I have been wanting to do is replace all of them. I want ceramics but Boca wants $319 for 24 bearings...quite a bit for a college student lol so I probably won't be able to get all ceramics, but Ty I also agree with you on your views -

I run ceramic bearings through real car drag racing and building chassis'/motors for real world drag racing, and I also have used them when my friends (team) would go drag racing street bikes just for the mere fact that ceramics have such an incredible resilience to heat and friction and they are just so much better point blank period through my experience.

So far, my drag chassis is a Inferno GT2 Race Spec with chassis braces, I have a R&B RT9 motor that has been modded by Rick Brake and am waiting for a Nova 28-7T I sent him a couple of weeks back to mod for me, foam tires, savox servos, and foam tires, and the back/middle/front has some heavy weight oil in the diffs (I think - I was putting car together while friend rebuilt all 3 diffs lol), so hopefully with this set up, I will pull some good times in 132 ft drag racing, I am just looking for those little tricks and things that you can do to shave a bit of time here and there you know I'm sure.
