Making power is one thing-getting it to the pavement is another. To this end, the BlackTrax crew installed a set of Nex GT Series coilovers. This set-up features a twin tube, low-pressure design, a 30mm piston, four-position dampening adjustment and separate ride height and spring pre-load adjustments. Additional suspension mods consist of Wicked Tuning tie rods, upper strut tower bar, upper control arms and radius rods, Kazama subframe spacers and a Stillen HICAS eliminator kit. Knowing the key to getting around a corner is braking, BlackTrax enlisted some choice upgrades to the stock equipment, including Hawk pads and sticky Kumho rubber from The Tire Rack.
Beyond suspension, chassis stiffening can really impact a car's controllability at the edge of adhesion, which is where USCC combatants will spend a lot of time. A six-point, mild steel roll bar was constructed out of 1.6-inch DOM tubing to keep the weak T-top structure from twisting under heavy g-loads.
BlackTrax says the V8's brutish grunt on the low end and nitrous-engulfed top end-combined with a stiff chassis, sorted suspension, overall attention to detail and weight savings-give this 90s superstar a good shot at USCC glory.
