Car Bounces after 60 ft. What is causing this??

looking way back when I was foot braking with leaf springs I couldn't bring the rpm's up very high as it preloaded the suspension..... always had to bring it up off idle and stomp to get up on the tire. Even if you lower the front suspension, you can see when you bring up the rpms, the left front is already pulling up significantly. Do you have a side profile shot of the car? It actually appeared to me that the front suspension was down quite a bit as it looked as if there was quite a bit of + camber that is usually the result of someone lowering the t-bars.

.....If it's a "race car" you'd absolutely love ladder bars on that ride.
