Frame or chassis options for A bodies

You just cant ever convince some people how good of a design the mopar suspension is. They call you a "hater" or "purist" ironically, people by these coilover kits for the WOW factor, and in my experience 99% of the average public isn't even capable of using all the handling potential in the mopar chassis. I have yet to see anyone actually outrun a leaf spring/torsion bar car, that is properly set up, with ANY of these "suspension conversions" I raced these cars for years, and STILL hold the track record at the fastest paved trioval short track in the US. On leafs and torsion bars. Hell, buddy baker was able to go 200 MPH in 1970 in a 4K pound B body with 15" bias ply tires.......torsion bars/leaf springs.....
