Ohlins TOS1U00 Road & Track DFV Front Left Coilover Strut Assembly

The Öhlins TOS1U00 is the left front Road & Track coilover strut unit, sold individually as a direct replacement or spare component for the Öhlins TOS MU00S1 coilover system. It is engineered specifically for the rear-wheel-drive BMW Z4 (G29) and Toyota GR Supra (A90) platform.

This inverted monotube strut is built around Öhlins' proprietary Dual Flow Valve (DFV) technology, which delivers symmetrical damping characteristics in both compression and rebound. The DFV design allows damper fluid to follow a consistent flow path in both directions, enabling the wheel and tire to return to the road surface quickly and effectively for improved grip and traction.

Key Features:

• DFV (Dual Flow Valve) Technology — a single gold knob adjusts all four damping parameters simultaneously: low-speed compression, high-speed compression, low-speed rebound, and high-speed rebound
• Inverted monotube damper design with lightweight aluminum shock body for reduced unsprung weight and improved heat dissipation
• Temperature-compensating needle bleed valve — expands as heat increases to maintain consistent damping rates across varying operating temperatures
• Threaded body ride height adjustment — the lower flange adjusts independently of the spring seat, preserving spring geometry and preventing travel limitation during height changes
• Reuses OEM upper mounts — no additional top hat hardware required for installation
• Sold individually — left front strut only

The Road & Track platform is engineered to deliver a true performance driving experience without sacrificing daily drivability. Whether navigating track curbing or road imperfections, the DFV system keeps the suspension composed and the tires planted. This unit is the ideal replacement component for drivers who need to service or replace the left front corner of their existing Öhlins TOS MU00S1 coilover kit.
