Product Details
Already have a performance-focused BMW E30? This AST 5200 Series coilover kit is the next piece for serious track tuning. These are 2-way adjustable coilovers with external reservoirs, letting you fine-tune compression and rebound damping separately. They are built for track use, handling heavy side loads and braking forces with their inverted strut design.
The MONOTUBE design in both front and rear dampers allows for separate adjustment of rebound (how fast the damper returns) and compression (how fast it compresses). You get 12 distinct positions for each adjustment, giving you the flexibility to dial in your suspension for specific track conditions or driving style. This helps reduce body roll, improve responsiveness, and keep your tires planted for better traction. The kit also includes camber-adjustable front top mounts and solid rear top mounts to further refine your front-end grip.
