LT80 or DRR or APEX

Ive got a big decision to make this winter , Ill give you guys an overview then tell me what you think . My daughter has just started racing MX here in WV. We a purchased a LT-80 with 105 kit motor, racing carb , DG exhaust , clutch mod , !8" rear tires , Extended arms , Wide axle + 3"spacers all around and stock suspension. Now my question is me being new to all this , am I going to be better off freshening up the LT and putting some suspension under it or go the route of DRR or Apex. Naturally Im after reliabilty, cost effciency , and broad band performance options . SUGGESTIONS WELCOME>>THANKS
