Full-Frame Chassis for Unibody Cars

[Silver69Camaro]

Prodigy,
I think there must be some miscommunication.

The ONLY way to install this chassis is to channel the body over the frame. The outriggers of the floor support are made to be the same width as the vehicle's pinchweld-to-pinchweld width. The floor of the vehicle is removed, right up to the pinchwelds, and the body is dropped on and new floor pans are made. So, like you said, the body is dropped 4" without any changes to the front and rear rail height. The body is NOT simply sitting on top of the frame.

As far as ride height is concerned, each frame is custom made to the customer's desires. If he wants a 10" rocker-to-ground clearance, fine. If he wants 2", no problem. He can have 2" in the front, and 5" in the rear if he wants. However, suspension is always left unchanged to maintain correct geometry.
