You need to get as much weight off the front as possible and any needed weight (battery, etc.) moved to the rear.
Weight transfer is the biggest thing to keeping traction, at launch its mainly just a tire and weight transfer issue, BUT once your full boost hits you are already moving so you dont have the instant transfer that will plant the tires. At that point its really a suspension game, you need that rear axle wanting to push its self into the ground.

what does your rear suspension consist of?? Does the drop use new springs or is it just drop brackets?? Usually drop springs are softer which will cause more axle wrap, axle wrap=loss of traction.

Now if you just have a slight traction problem im sure moving some weight around and a different shock setup will help but in your situation IMHO its suspension.
