Granted, double-adjustable shocks would add some wow factor, but Buck says they're overkill for a 9-second street car. He prefers the tuning simplicity of a single-adjustable shock, and notes that plenty of cars run single-digit e.t.'s with old-school 90/10 shocks. These units from Strange feature rugged steel construction and 10 rebound settings. At just $119 each, they're a fraction of the price compared to double-adjustable shocks.
