AST is one of the most advanced and high quality suspension manufacturers in the game. Any of their products will leave you completely satisfied and even more in love with your car than you thought possible

The Sportline 1, or 4100 series, is AST's "entry level" product, but this does not mean it is low quality or cheap. Even though it is the cheapest product available for MINIs, it is still leagues better than most other suspension.

  •     Monotube design
  •     Rebound adjustment with one knob.
  •     Adjust platform allows the use to adjust the ride height of your car.
  •     Specially designed to keep maximum stroke, even with a lower ride height, and are finished with a KTL coating for an extremely hardy finish.
Monotube Design

Monotube design is essential for performance. The oil and nitrogen are separated by a floating piston, and allows the use of a larger piston, increasing the damper performance and sensitivity felt by the driver, all this added together produces more grip, gives more control and driver feedback from your vehicle.
What is a rebound adjustment?

Rebound controls the rate of extension of your shock absorber. By changing the rebound you can directly change the characteristics of the vehicle.

Technical specifications:

  •     Floating piston design with high pressure nitrogen eliminates cavitation around the piston.
  •     22mm / 14mm diameter shaft struts, non-inverted.
  •     Steel cylinder body shocks, non-inverted.
  •     Rebound adjustable (''Singles'').
  •     Low friction seal.
  •     Adjuster knobs permanently mounted on the dampers, no need for special tools.
  •     Rubber bushings for ''eye'' shock mounts.
  •     Optional spherical top mounts.
  •     Optional DDP piston (double digressive).
  •     Rebuildable and fully serviceable.
  •     Optional custom valving.

Customers' comments

out of the box and snapped right on -- 5 minutes...looks great and goes with the black jack on the roof.

Ordered a small part from you guys on 22nd December and received it in New Zealand on 5th Jan. It came direct from USA not from China. Tracing information every day on progress of parcel. Best I have ever had. I know where I will be buying my Mini parts from now on. Very pleased I found you.

Just purchased the Black "slat" Grill to replace the standard chrome slat grill on my R56, I installed it with the original chrome trim pieces, looks fantastic for $100. Not knowing what I was doing at first and it still only took 10 mins. to install.
