Product Details
Monotube coilovers with external reservoirs. These AST 5200 Series coilovers are built for serious performance driving, letting you dial in your suspension for track days. The part number is RIV-B2115SD.
You can adjust both the rebound (how fast the shock returns) and compression (how fast it compresses) independently. This lets you fine-tune how the car handles corners, braking, and bumps. The inverted strut design handles side loads and braking forces well. Springs are included, and you get camber-adjustable front top mounts where applicable, plus solid rear top mounts. This allows for more front-end grip adjustment.
