Get on Afcos page it breaks down all the suspension types. If your not real serious about being super fast buy a swing arm car to get your feet wet. Then opt to go 4bar 4bar. Buy a chassis that has good local support. Donnie at lightning is great help and has great setup sheets. And Kramer will always help when he can. I would stay away from the lasers. Shaw would be another good car as Kevin Shaw is good help as well... make sure you get scales too they are a big part of setup. If you need any more info send me a pm and ill give you my phone number
