Suspension Adjustments for Track Conditions Soft Surface On soft ground, sand, and especially mud, consider increasing compression damping front and rear. Sand often requires a bit more rebound damping to minimize rear end kick. Although sand bumps are usually larger, there’s more distance between them, giving the shock more time to recover.
