Benefits include:

• High end, track ready suspension that is totally streetable.
• Fully upgradeable to 5300 spec.
• Rebound and Compression Adjustable ('Doubles'), with a remote reservoir.
• Remote reservoirs allow additional travel, heat dissipation and increased 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 monoevers.
• Aluminum cylinder, threaded body shocks, factory mounting style.
• New low friction seal on all AST dampings.
• 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 shafts.
• Optional DDP piston (double digressive).
• Fully service and rebuildable.
• Revalvable for specific characteristics.
