In the world of motorsports, most of the racing teams use double, tripple, and even quadruple adjustable shocks. This allows teams to fine tune every aspect of handling, braking and acceleration suspension dynamics. The 4 way adjustables have Low Speed Compression, High Speed Compression, Low Speed Rebound and High Speed Rebound.

The difference between high speed compression and low speed compression is the Shock Piston Velocity. In other words how fast the shock is moving per second. Shock designers include a "blow off" valve into the shock design. So for example apex on a steep racetrack curb. The front tire will compress extremely fast and the front compression high speed blow off valve will operate in this manner. Most of the time you are within the Low Speed Shaft Speed so Critical in Tuning.

The Indy Doubles Such as the MOTON Clubsports, Penske 8300, and Callaway Eibach Multi PRO allow you to fine tune the low speed dampening characteristics. Both Compression and Rebound Independently.

The Indy Tripples Are also available in MOTON MOTORSPORTS and Penske 8750. These have High Speed Compression Adjustment. While they are very nice I think most of us fall in the Double Category.
