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.
