Are you changing classes? Are you moving to street prepared, STR, or ? I'd stay in DS. If you do, any springs, brakes, etc. are not allowed. I would change wheels to 17x7.5 in the front and 18x9 in the rear. I'd get the lightest wheels that I could find. I'd mount 225/40s on the front and 275/35s on the rear. Less weight would help. Then I'd use crash bolts in the front to get the negative camber and proper caster in the front. You've already changed front sway bars; so you don't need anything there. Good luck.
