How do I adjust the ride height and rebound on these coilovers?

You can adjust the ride height by changing the spring perch location. The rebound damping is adjusted using the knob on the top of the damper, with 12 distinct positions to choose from.

What is the benefit of a monotube damper design?

Monotube dampers use a larger piston, which gives better control over rebound damping. They also prevent aeration and foaming of the oil, leading to more responsive valving and consistent performance.

Are these coilovers suitable for daily driving as well as track use?

Yes, these coilovers are designed to offer a balance between track performance and road comfort. You can fine-tune the rebound and ride height to achieve your ideal setup for daily driving.

Product Details

Worn-out suspension causes poor handling and ride comfort. The AST 5100 Competition Series coilovers are a direct fix for your 2021-2023 BMW M4 and 2022-2023 M3. These are built for drivers who want track performance but also need a balanced ride for daily driving. You can fine-tune grip by adjusting rebound and ride height.

These coilovers use a monotube design. That means a larger piston inside controls the rebound damping. This design prevents air from mixing with the oil, so the damping is more responsive. The dampers are also rebuildable at a certified AST service center if any issues come up.
