who makes best coil over front suspension

If Ehrenberg can take a 69 Valiant with stock torsion bar suspension and kick *** at One Lap of America with, Vipers and Vettes, I don't see the need for any of the coil over stuff......unless perhaps a Hemi swap is involved. Other than that, it's a waste of money and only for bragging IMO. The Mopar front suspension is one of the best of its time. Perhaps the best. Especially with a few small modifications.
