How do I adjust the rebound on these coilovers?

You can adjust the rebound damping using the knob located on the top of each damper. There are 12 distinct positions, each offering a different setting for the return stroke of the suspension.

What is the benefit of a monotube damper design?

Monotube dampers use a larger piston and have no aeration or foaming issues. This results in more consistent and responsive damping control, especially during hard driving.

Can I adjust the camber with this kit?

Yes, this kit includes camber-adjustable front top mounts. This allows you to fine-tune your front-end alignment for improved cornering grip and handling characteristics.

Product Details

AST makes these 5100 Competition coilovers for the 2019-2023 BMW 330i. If you're looking to improve grip for track days or want a better balance for daily driving, these are a solid choice. They let you adjust rebound damping and ride height to get the handling just right. This set includes springs, front and rear top mounts, and the coilovers themselves.

The monotube design uses a large piston for rebound control, which means more responsive damping without aeration or foaming. These dampers are also rebuildable at a certified AST service center if any issues come up. The initial spring rates are based on AST's development and testing, but you can fine-tune them by adjusting the rebound knob or changing the ride height. You get 12 rebound positions to choose from, with each click offering a distinct feel.
