The Whiteline Front Caster Adjusting Bush Kit fixes to the front suspension and allows adjustment of alignment and replacement of worn or tired bushes.The Bush kits are straightforward to install and are application specific, ideal for street, stage or circuit driving where alignment change is required. The bushes themselves are eccentric design for accurate adjustment and a fitted with a low compliance polyurethane bush which provides excellent long term durability and optimises steering feedback and ensures sharp suspension feel.Caster adjustment allows the wheel to move laterally front to back relative to the suspension components. Caster adjustment combines with Camber to ensure handling is optimised, where a decrease in understeer is required more positive caster is advised and where a decrease in oversteer is required, more negative caster is recommended (in general).Whiteline Performance Products including sway bar/anti-roll kits and bracing & alignment kits are
