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

Ride height is adjusted by threading the spring perch up or down on the shock body. Rebound damping is adjusted using the knob at the top of the damper, with 12 distinct positions to choose from. Refer to the manufacturer's instructions for specific details on adjustment procedures.

What is the benefit of a monotube damper design?

Monotube dampers use a larger piston, which allows for better control over rebound damping. This design also prevents aeration and foaming of the oil, resulting in more consistent and responsive damping performance, especially under hard use.

Can these coilovers be rebuilt if something goes wrong?

Yes, these AST coilovers are designed to be rebuildable. If any issues arise, they can be serviced and repaired at a certified AST service center, extending the life of the suspension components.

About this part

Product Details

Worn-out suspension causes poor handling and ride comfort. The AST 5100 Comp Coilovers (Part# ACC-B2302S/3D) are a direct fix for your 2013-2016 BMW 320i xDrive, offering track-ready performance and adjustable ride height. These are built for drivers who want to optimize grip and handling, whether for track days or a more balanced daily drive.

These coilovers feature a monotube design, which uses a larger piston to control rebound damping. This design prevents aeration and foaming, leading to more responsive valving. You can adjust the rebound in 12 distinct positions to fine-tune your car's handling. The kit includes front and rear dampers with adjustable ride height, plus camber-adjustable front top mounts and solid rear top mounts. This allows for more precise wheel alignment to improve front-end grip.
