Radius arms play a crucial role in controlling longitudinal wheel movement and stabilising suspension behaviour under braking, acceleration and cornering. By managing how the front suspension locates and pivots, radius arms help maintain correct wheel alignment, reduce unwanted fore and aft movement and keep the vehicle stable and predictable. Whiteline radius arms are engineered to increase rigidity, refine geometry and deliver a more confident, responsive driving feel.
With stronger construction, precision bushings and geometry focused design, Whiteline radius arms transform steering stability, improve braking confidence and create a more planted feel on the road. Extensive real world testing and performance driven engineering ensure every component delivers measurable improvements to handling accuracy, grip and overall vehicle balance. The result is a sharper, more composed driving experience that enhances both everyday and spirited driving.
Why Upgrade Suspension
Factory suspension often prioritises comfort over dynamic precision, which can lead to unwanted flex and alignment change when the vehicle is under load. Upgrading radius arms helps reduce squat, dive and unstable weight transfer, creating a more controlled and predictable chassis.
Improved rigidity reduces deflection and maintains better geometry throughout the suspension’s movement. This means increased grip, more consistent tyre contact and sharper, more dependable handling. Whether commuting or pushing harder on the weekend, upgraded radius arms bring confidence, stability and enhanced feedback to every corner.
Why Choose Whiteline
Whiteline radius arms are built on a foundation of engineering expertise, precision manufacturing and extensive durability testing. High strength materials and advanced polyurethane ensure long term stability, consistent alignment control and reduced flex even in demanding conditions.
Each arm is designed for specific vehicle platforms to deliver the most effective geometry correction and handling improvement. Whiteline’s reputation for sharper steering, improved grip and enhanced stability makes these upgrades trusted worldwide by enthusiasts and performance drivers.
Whiteline Radius Arm Range
Whiteline offers a specialised range of radius arm solutions designed to improve fore and aft control, alignment accuracy and stability under load.
Radius Arms: Increase rigidity, improve stability under braking and maintain precise wheel alignment for a more predictable steering feel.
Radius Arm Kits: Complete assemblies designed to reduce deflection, correct geometry and deliver stronger grip and more consistent handling performance.
How Whiteline Improves Vehicle Dynamics
Whiteline radius arms reduce unwanted movement in the suspension, maintaining consistent geometry during acceleration, braking and cornering. This results in a sharper steering response and a more stable, planted chassis.
Better tyre contact through improved alignment stability increases grip and mid corner control. The vehicle feels more predictable at the limit, responding cleanly to driver inputs and providing a more confident and enjoyable driving experience.

SKU: KTA406Benefit Note: These Whiteline front lower control arms feature significant geometry gains with +0.5deg 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 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 noticeably 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.

SKU: KTA416Benefit Note:Complete replacement control arms featuring offset bushings that are primarily designed to improve traction and cornering grip under power. Increasing static caster to both front wheels. The special low compliance bushings reduce caster wind-back and maintain tighter tolerances between static and 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 bush compliance.
