AST 5300 Coilovers - BMW E46 M3

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.
