All you need for a decent launch is better rubber. But the rubber you really need will not fit on those rims. Look into getting some rims that will fit your driving preferences. Perhaps Draglites or Dragstars if all you do is track. And maybe some Cobra R's or tasteful 17's. This way you can easily fit 275's or 285's like I have on the 17X9 Cobra R's, 245's up front though!!!!
