For the best performance on the track, AST Suspension designed the Competition 3-way adjustable series. The 5300 Series shock absorbers are rebound adjustable in 12 positions.

 

The highspeed compression is adjustable in 12 positions and the lowspeed compression is adjustable in 14 positions. Both compression adjustments are made using an external canister. All adjusters work completely independent.

 

Many years of technical knowledge, testing and experience has been refined, fettled and brought together to create a perfect balance between springs and damper characteristics. This makes it a versatile product for every customer. The 5300 series shock absorbers are the best solution for every race team. Once installed the shock absorbers are easy to setup, highly reliable and require low maintenance during the season because of the high grade of materials that are used.

 

The 5300 series shock absorbers are championship winning shock absorbers and are worldwide renowned for their performance at every level.

 

Benefits include:

  • High end, track ready suspension.
  • Rebound, Low & Hi Speed Compression Adjustable ('Triples'), with a remote reservoir.
  • Remote reservoirs allow additional travel, heat dissipation and oil/nitrogen gas capacity.
  • 44.5mm diameter shaft struts are inverted and offer exceptional strength, which in turn reduces geometry change under corner and braking manoeuvres.
  • Aluminium cylinder, threaded body shocks, factory mounting style.
  • New low friction seal on all AST dampers.
  • Spherical lower ''eye'' shock mounts.
  • Reservoir with hose or piggyback (piggyback examples: '08 STI & BMW E36 rears).
  • Spherical upper shock mount assemblies.
  • Synthetic hydraulic fluid.
  • Optional DLC Coated 44,5mm inverted shafts.
  • Optional DDP piston (double digressive).
  • Fully serviceable and rebuildable.
  • Revalvable for specific characteristics.
Geometry Explained

Geometry
Suspension geometry is the positioning and angular movement of the suspension arms and the effect that they have upon the movement of the wheel and tyre. It is caused by the different components of the suspension system all moving in their designed paths, which together generate changes in direction and multiple forces on the wheel and tyre, making the steering and suspension operate in particular ways.

Effortless & Accurate

The results have exceeded my expectations, I'm really pleased with the car. The ride is similar to stock but it's taken the jitteryness away over small ripples in the road. I was slightly apprehensive that the stock dampers might be exposed but I needn't have worried, the car rides exactly as I'd expect & want from a roadgoing M-car. The real revelation is the steering, I could feel the difference as soon as I turned out of your premises. Gone is the sluggish, heavy response - it's now quick, effortless & accurate, almost as if the power steering had been switched off beforehand. The car feels like it's 200kg lighter but at the same time, more solid & composed. For me, it's a perfectly-judged road setup - thanks again

Recently bought a 2025 M3 LCI which seemed ok out of the box. In the wet there was quite bad understeer and slightly unpredictable transition into oversteer. The CS+ handling package transformed the car. The grip is ridiculous, feel is improved, can really lean on the car. Driving in the wet traction is like it’s dry, extremely stable. Car is predictable, any transition to understeer or oversteer is communicated and feels like slow motion with plenty of time to correct. Feel like all the handling of a CS car with all the comfort or a regular M car. Absolutely love the car now.
