I have DSE subframe connectors and a Alston 8-point cage with solid body mounts. I have about 150 miles on the car so far. Shaking it down before paint...69 Trans Am scheme. Its extremely loud and fast. I think I'm just gonna fab up some aluminum door panels and a rear seat delete. Not gonna put windows in it to save weight and hassel. It will never see rain anyway!
