stiff ass springs, r compounds, no amenities except AC, monsterous wing, front splitter... no shit it beats the zr1. All those mods to a zr1 and it will more than likely beat 7:22, imo.

Then the SRT engineers went hunting for good suspension pieces, finding race-specification dampers from KW Suspension to be just about exactly what they had in mind. These shocks are 14-way adjustable in compression and rebound, and they permit ride-height adjustment as well, so the car can be lowered right down to 3 inches of ground clearance.

With spring rates that are about twice as firm as the standard Viper and a front antiroll bar some 20 percent stiffer, the ACR Viper rides pretty hard, yet it didn't feel too jarring to us at Willow Springs. Other than a couple of bumpy points on the track where the car would bounce slightly off course, the Viper circulated surprisingly smoothly. Despite a fairly serious lecture from chief engineer Helbig about not crashing, we discovered to our relief that this 600-hp car with a big racy wing is actually pretty easy to drive.
