Lightweight rear adjustable upper arms for Toyota GR Yaris. Price is per pair (for one car).

Technical Suspension Upgrade: Rod-Ends and Spherical Bearings

Traditional suspension systems use rubber bushings that can flex under stress, leading to deflection and altered geometry. By replacing these with rod-ends and spherical bearings, you achieve a stiffer wishbone setup that is essential for motorsport and high-performance applications.

Technical Benefits:

• Consistent Geometry: Minimizes deflection to maintain precise wheel alignment under load.


• Enhanced Handling: Reduces compliance in the suspension, resulting in more predictable steering response and improved cornering performance.


• Increased Durability: Stiffer components better resist wear and deformation during high-stress, competitive driving.


• Improved Feedback: Eliminates slack inherent in rubber bushings, ensuring immediate and accurate response from the suspension.


• Robust Load Handling: Provides a more secure connection between components, critical for sustaining performance under heavy loads.

Product functionalities:

• Camber adjustability extended with turnbuckle screw. The adjustment range is ±15 mm, provides approximately ±4.4 degrees of camber adjustment.


• Much lighter, also from metal wishbones made by other companies.


• Uses uniballs which eliminates rubber bushings deflection and gives much more direct and predictable response.


• Stiffer and stronger than OEM part – designed to withstand track racing and rally abuse.


• Extra room for thicker shocks.


• Supports longer shock travel.

Features:

• Precisely CNC machined out of aluminium.


• Welded with high strength steel.


• Black coating for nice look and corrosion resistance.


• Part comes preassembled ready to install.


• Compatible both with OEM and Verkline subframes and uprights.

What is included:

• Two aluminium wishbones


• Two turnbuckles with super slim nuts


• Two M18 rod ends


• Two rubber caps for rod ends


• Two PTFE motorsport uniballs


• Printed install instructions (7 pages)

Used in:
- Toyota GR Yaris 2020+
- Toyota GR Corolla GZEA14

Note: Installation of this rear insert kit will introduce some additional some NVH (noise, vibration, and harshness) transfer into the cabin.
