Definitely get the SFC's on the car asap, that should've been the first mod period, these cars flew way to much. Also look into different front springs for better weight transfer and possibly get a rear shock valved for small tires (10.5 width) to help plant the rear. With solid bushings in the rear set the pinion angle between 1-2* down and have the tq boxes welded up because if they start to flex and tear then all of this is for nothing.
