Race shocks on the street.

I ordered a set of AFCO leaf springs for the duster, and will go with either QA-1 or Calvert adjustable rear shocks. But not sure if i want to run the Calvert 90/10 race shock on the street or buy the QA-1 single adjustable for the fronts. Huge price difference on the fronts, About $100.00 per shock.

Anybody running any kin of 90/10 on the street?
