Spax PSX Adjustable Damped Suspension Kits include uprated, shortened, 28 stage on-car adjustable dampers and a set of matched springs to give your car an all round upgrade in road holding and body control.Spax engineers have developed these dampers to produce maximum control and handling. The PSX dampers are uprated, shortened and pressurised with Krypton gas. This produces not only superior low speed ride quality, but also high speed performance that is ultra stable, fade free and therefore significantly improved. The result is maximum cornering speed and traction, minimum braking distance and roll. Optimal handling results in better driver control and shorter stopping distances and this leads to a safer and more enjoyable drive.PSX dampers are ideal for fast road applications and occasional trackday use because they have a wide range of on car damping adjustment with no dismantling. You can transform your car's handling from daily-driver to trackday machine in about a minute!Spax PS
