I am pretty sure it was discount exempt when I bought them and remember getting the discount during the checkout on the web. It did surprise me at the time and wondered if the discount was because it was some promotion where if you had an order over $1000 you would get a 10% discount. Either way, I didn't argue the price.
My suspension I have build with new Firm Feel upper control arms and sway bars, poly bushing everywhere, boxed lower arms, heavy duty lower control arm pins, strut rods, adjusting bolts, and .96 torsion bars. The rear is all poly bushings with A-body HD springs and the 3/4 re-location kit. Plus the other obvious parts which are the Edelbrock IAS shocks.
