Looking for the perfect road balance for everyday driving? The 5100 Street Suspension delivers comfort, control, and confidence in every corner. This monotube coilover system is 1-way adjustable for rebound and ride height, allowing you to fine-tune your setup for maximum grip and stability. It comes with vehicle-specific spring rates, OEM-compatible top mounts, and rebuildable dampers for long-lasting performance. Proudly made in the Netherlands, the 5100 STREET Suspension offers the ideal blend of everyday comfort and precise handling - engineered for drivers who want performance without compromise.

-   Monotube dampers offer a large piston to control the adjustability of rebound damping. These dampers can adjust in rebound (return to extension). Front dampers utilize a coilover design, the rear is a divorced setup like OEM.
