Spring Rates
Spring rates determine the available amount of bump and rebound movement. Higher spring rates limit this movement in much the same way as a stabilizer bar. For street conditions, the ideal spring rates would be where the suspension movement ceases just before the bump rubbers come into action. Astute "car sorters" use stabilizer bars and spring rates in conjunction with one another to achieve the best results. Altering spring rates may also require re-specification of the bump-rebound qualities of shock absorbers. For example, where stronger springs are required, a shock absorber with stronger rebound and softer bump should be selected.

Oversteer: (Rear breaking traction) As with understeer, both rigid and soft suspensions can cause oversteer . With "roll oversteer" the car leans heavily, hitting the bump rubbers and causing a skipping action of the rear end, often resulting in an inversion of the car. "Rigid oversteer" is brought about by a tight suspension set-up which does transfer sufficient weight to the wheel doing all the work.

Understeer: (Front breaking traction) We emphasis that understeer can be caused by both too hard or too soft suspension. The hard suspension will have a tendency to "jump" on unsmooth surfaces, thus lessening contact between tires and the road. With soft suspension the tendency to accentuate centrifugal forces by excessive body roll causes the type of understeer that most of us have experienced at one time or another.
