Phazer MTX questions

I just picked up my phazer mtx and want to cut weight, I installed new exhaust, to cut weight, but installed a float plate for a obvious reason, removed windshield and bracket, and reflectors, what else do you got for me. I do have to maintain trailability I.e. boogie wheels, etc.also I want to increase track length, anyone point me where to look to do it. Maybe direction/instructions? Thanks!
