My b4.1 worlds is pushing alittle bit. Track is hard pack, wet, blue groove, outdoor. Weight is in the usual places. I've got losi 32.5 wt in the front (inside tower, outside arm, #2 piston) and losi 27.5 wt in the back (inside tower, inside arm, #2 piston). To fix this problem I would want to go to a lighter wt in the front, correct?
