These Whiteline front lower control arms feature significant geometry gains with -1.0deg camber and +0.75deg caster improvements into these arms to optimise wheel alignments settings for track performance. Caster increases dynamic negative camber on the outside wheel whilst turning, offering more grip without introducing the tyre wear associated with static negative camber. Furthermore the increase in caster improves traction and increases the self-centring effect of the steering. Throw this altogether and the small change in additional caster improves the front-end grip and handling considerably. Whiteline's rear mounted bushing combines the superior mechanical properties of synthetic elastomer formulation with high quality sealed bearing assembly permitting smooth movement of the arm as the wheel moves up and down. Complemented by a front bushing utilizing an oversized heavy duty crush tube, resulting in dramatic improvements to steering precision, most not iceably reduced 'toe-change' during hard cornering, creating impressive turn-in ability! The more positive location of the arm through the range of suspension movement and gains in alignment geometry ensures the car feels more responsive and engaging at turn-in, mid corner and corner exit.
