StreetGRIP ;front coil springs improve the handling, ride quality and lower the stance of your Chevrolet Camaro or Pontiac Firebird. They feature a dual rate design which gives your classic the best of both worlds. The soft spring section helps your car to comfortably transition over small road irregularities. As your car's springs further compress such as when encountering large bumps and cornering loads the design transition to the firmer spring rate. StreetGRIP coil springs are CNC cold wound from high tensile premium steel by then powder coated for long-lasting, consistent operation. RideTech works closely with Hyperco, our technology partner, to develop F-Body specific springs for exceptional performance and comfort.
