Performance and use

Inverse-threaded turnbuckles improve handling by reducing play and providing a more direct response in corners. Their light weight minimizes inertia while maintaining sufficient rigidity for critical joints. The surface treatment and machining precision ensure long life even under demanding race conditions, while preserving a premium aesthetic.

Compatibility and installation

For installation, verify the left/right identification and tighten to the recommended torque to preserve play and performance, while avoiding any over-tightening.
