I have a cold air intake, cat-back exhaust, (suspenion parts I am installing next week) coilovers, thicker rear sway bar, and camber alignment kit.

What can I do to improve all around preformance. And keep it reliable fairly good gas mileage and make able to easily withstand operator error, and racing conditions? I use my owner's manuel schedule to maintaine the car.

I am considering installing:
*AEM, HKS, or Toda cams and cam gears.
*Toda header.
*Comptech cat. converter but I am not sure if that will make a differance.
*Skunk2, or Venom intake mainfold
*16" or 17" wheels with a little wider tire. Volk, ROTA, or Velox
*spacers
*costum valve cover
*DC sports, or Skunk2 Short shifter.
*ACT or Spoon racing clutch and flywheel.
