Torsion Bars?

Yes, we did it when I was at XV Motorsports - we rented a four post tester and ran tests on the suspension and recording the suspension movement, geometry, etc.
I chose the T bar rates I carry based on all my experience to make things easier for anyone trying to make a choices. The other half of choosing t bars are the shocks. Shock rates seem to be a secret that the manufacturers hold close to their hearts...Again, my offerings are based on my knowledge and experience.
