✅ Precise chassis geometry on the rear axle thanks to adjustable upper control arms
✅ Extended fall and anti-squat area for maximum traction
✅ Motorsport-proven design for track, street & performance

ALL BENEFITS AT A GLANCE

The adjustable upper rear wishbones were specifically developed for performance and motorsport applications, allowing for precise adjustment of the rear axle geometry. The extended adjustment options enable optimization of both camber and anti-squat characteristics, thereby improving tire contact and significantly increasing cornering traction.

The high-strength construction using T45 steel tubing ensures exceptional structural stability while maintaining low weight. This keeps the chassis geometry stable and reproducible even under high loads, resulting in more controlled and precise handling.

The combination of precision adjustment elements and high-quality motorsport uniball bearings enables backlash-free and permanently stable axle guidance. Protective boots further protect the bearings from dust and moisture, significantly increasing the component lifespan.

The development is based on a complete engineering process including 3D laser scanning, CAD design, FEA analysis, and extensive driving tests. The result is a plug-and-play system that can be mounted directly onto OEM subframes and axle components without modifications.
