WHITELINE KCA406 Front L-arm rear support with additional +0.30 'for LEGACY BM / BR

Added caster improves turn in response increases directional stability and dynamic negative camber (on turn). Caster also improves steering feel and self center whilst maximising tyre contact patch during braking and accelerating

KCA406 is designed to add +/- 0.5 degree static caster to both front wheels. The special low compliance bushings reduce caster wind-back & maintain tighter tolerances between static & dynamic alignment settings. The additional caster coupled with the firmer bushings serve to dramatically sharpen initial turn-in response - forcing more consistent alignment angles through the corner due to the reduced bushing compliance.
