260hp is not god like. you will have to mod the motor to get power. bolt ons just don't cut it unless you are set to drag. slicks, built rear the whole nine.
Seems to be alot of "well I really don't run the 1/4 but heres what I think answers here" So let me tell you what I know. I traded a WS6 for my GT. I have a good friend who owns and races a vert WS6, COMPLETELY stock. I never ran my WS6, but knew when I bought the GT that it wasn't anywhere near as fast. Got a good deal and had some probs with the WS6 that didn't have to do with performance is why I traded. Anyway.......I know many who race (as in drag strip) their GT's with many bolt-ons and barely break 14's, while my buds WS6 vert runs 13.4 bonestock. Face the facts, you are not gonna compete with an LS1 without a PA, unless you get suspension and motor hooked perfect, and learn how to drive. Buy a SC or a LS1. Otherwise, DRIVE IT LIKE YOU STOLE IT. At least you'll look cool!
