Not really a bolt on but get a 3.46 differential as the biggest notacable difference. I would assume you are tracking this car though or want too and I would focus on getting r-coumpounds/ltw wheels and work on the suspension with sways and lower the car etc. the shark injector gives me that extra 500rpm for autox events etc.
