I recently started being less confident today i was with my friend in the bmx parc was doing backflips and everything my esc tabs broke so now its holded in with double sided tape. But my car feels "slugish" i don't know what i cant do i lowered the car a little bit more in the front maybe i need a better servo savers because of the grip of the backflip lps now maybe i should play with the diffs i have 30k front 20k rear i think. What should i do?
