Best Aftermarket Suspension Set-up

If torsion bars were so great, why did Ram Trucks go to Coil springs? I'm no engineer, but I think the length of the bars in some way make movement further from the front end to the rest of the car. Coil springs are limited to insolated control arms with rubber bushings.

If coil overs are so great, why do F1 cars use torsion bars?

Oh, right. It's because the entire weight of the torsion bar is sprung, and they can be mounted lower. So unsprung weight is reduced and the CG is lowered. They also have a motion ratio of 1, so, basically more efficient than coil springs when it comes to suspension design. Their drawbacks are all space related, not performance related.
