Öhlins DFV Road & Track Suspension Upgrade for B9 Audi RS4 / RS5

The Öhlins Road & Track coilovers for Audi RS4 and RS5 B9 are built for a platform that already arrives with serious performance intent. The RS4 (2018-present) and RS5 (2019-present) carry the chassis, power, and drivetrain to be genuinely fast; this kit gives the suspension the capability to match. Whether you’re pushing the RS4 through a technical circuit section or using the RS5 as a daily that occasionally sees track time, the Öhlins Road & Track kit handles both without compromise.

How the DFV System Works

• Öhlins’ Dual Flow Valve (DFV) technology handles the transition between road and race damping with a single adjustment. Turning the gold knob clockwise engages race mode across all four damping zones at once: low-speed compression, high-speed compression, low-speed rebound, and high-speed rebound. Reverse it and the damper returns to a more relaxed road setting. No tools, no separate adjustments per corner. On track, the DFV internals respond quickly to surface changes, keeping all four tires loaded through corners and under hard braking. The RS4 and RS5 already put power down effectively through quattro; this kit gives the chassis the damping support to make the most of that traction at the limit. Off track, the same system softens its response and absorbs road imperfections without the harshness that typically comes with a high spring rate setup.

Suspension Specs and Adjustment

• Both the front and rear use aluminum monotube shock absorbers, keeping unsprung weight low across both axles. Each corner includes a spring preload adjuster and a separate damper length adjuster, so ride height and spring load are tuned independently rather than as a combined adjustment. Front and rear lowering range runs approximately 10 to 35 mm on both ends, with a 120 N/mm spring rate up front and a 140 N/mm spring rate at the rear. The stiffer rear rate supports the weight balance and traction demands of the quattro platform under hard driving. All four corners retain the original Audi top mounts, keeping installation straightforward. The 1-way 25-click adjuster covers both compression and rebound, giving enough resolution to meaningfully change the feel of the car without requiring a full setup session to dial it in.

Frequently Asked Questions

Do these Öhlins Road & Track coilovers fit both the Audi RS4 and RS5 B9? Yes. The Öhlins Road & Track coilovers are designed to fit the Audi RS4 B9 (2018-present) and the Audi RS5 B9 (2019-present). Contact Bulletproof Automotive before ordering to confirm fitment for your specific build, trim level, or regional variant.

How does the DFV adjustment work on the Audi RS4 and RS5 B9 coilover kit? The Dual Flow Valve (DFV) uses a single gold knob on each damper. Turning it clockwise engages race mode, adjusting low-speed compression, high-speed compression, low-speed rebound, and high-speed rebound all at once. Turning it back returns the damper to road mode. No tools are required for the adjustment.

What is the ride height adjustment range for these coilovers? Both the front and rear dampers offer approximately 10 to 35 mm of lowering adjustment. Each corner uses a separate damper length adjuster, so ride height and spring preload can be set independently of one another.

Do these coilovers require new top mounts? No. Both the front and rear assemblies are designed to use the original Audi top mounts, so no additional top mount purchase is required for a standard installation.

What are the spring rates on the Öhlins RS4 and RS5 B9 coilover kit? The front spring rate is 120 N/mm and the rear spring rate is 140 N/mm. The stiffer rear rate supports the weight balance and traction demands of the quattro platform under hard driving conditions.

Can these dampers be rebuilt after extended track use? Yes. Every damper in the Öhlins Road & Track kit for Audi RS4 and RS5 B9 is fully rebuildable. This allows for servicing after heavy use and makes custom tuning possible for drivers who want to optimize the setup for a specific track or driving style.
