spring force (at the wheel). This setting will improve high-speed
cornering on smoother terrain by lowering the center of gravity
and providing a firmer suspension feel. Body roll, brake dive, and
squat will be reduced.
Spring rate (at the wheel) increases as the lower shock mounting
position is moved from position (1) to position (4). This is
equivalent to using stiffer springs. Use higher spring rate settings
for flatter terrain with smaller and fewer bumps, and lower spring
rate settings for bigger bumps.

Ride height decreases as the lower shock mounting position is
moved from position (1) to position (4). Each pair of lower shock
mounting holes (1,2 and 3,4) has equal ride height. Use lower ride
height for high-speed cornering and flat terrain, and when racing
on relatively smooth tracks. Increase the ride height for rougher
terrain and tracks.

Upper Shock Mounting Positions

The upper shock mounting positions will have suspension effects
opposite from the lower shock mounting positions.
Spring rate (at the wheel), increases as the upper shock
mounting position is moved from position (A) to position (B).
Ride height is not affected by changes in the upper shock
mounting position.
Use the chart below to see the effect of the various shock
mounting positions. The horizontal length of the lines indicates
the amount of suspension travel. The angle or slope of the lines
indicates the spring rate (at the wheel).
