Details


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.

Features:
  •     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.

Fit and finish were perfect. Mounted right up, and looks great.

Hi,
I recently purchased the belt tensioner from Alta and had it installed. Had I only known over the past several thousand miles that my shock was bad, I would have changed it sooner. The shop guys brought the old one out to show me that it was completely useless. Since replacing it my mileage has increased dramatically, and performance as well. apparently the drive belt was slipping on the super charger. And power, all I can say is "Yeah, Baby". Thanks guys for making this part available.
Best Regards,
Ron
