What is the most efficient size of a slick for a 99 superchrged gt with 400 whp. I am hoping to runa 15 or 16 inch rim with either a pure wrinkle wall slick or an et street type tire. Can someone give me some advice on the maximum width and height of the slick to run. Also what is the backspace for this rim so it clears the brakes and what is the lug pattern for it.
