Drop ETs with KONI's SPA-1s

SPA-1 Adjustable Drag Shocks feature velocity-sensing valving that allows the front of a car to rise only as much as needed. Once maximum launch traction is attained, the shocks enable the front of the car to settle down quickly, which enables you to take advantage of your car's good aerodynamic qualities. SPA-1 shocks are not for street use, substantially heavy cars, or cars with big block engines.
