Description

Part #: RIV-F4001S

You are that person who takes the performance of your car more serious. AST 2-WAY MOTORSPORT SUSPENSION is primarily engineered for track enthusiasts. Allowing you to experience sports car driving at its finest. Challenge your vehicle by adjusting the compression and rebound separately with a remote reservoir. Each adjustment position provides distinct feedback, delivering a unique driving sensation. The inverted strut design is engineered to handle heavy side loads and braking forces. Both the front and rear dampers in this kit feature a MONOTUBE coilover design. You have the flexibility to adjust spring rates on these dampers. With this suspension you have the capability to fine-tune and customize two critical aspects of your vehicle's suspension. You can adjust the rebound, means you can control the return to extension of your dampers, enabling you to attain the ideal road balance tailored to your specific requirements. With 12 distinct positions to choose from, each adjustment delivers distinct feedback and a unique driving experience. Besides that you can adjust the compression adjustment of this suspension. It allows you to control how quickly the suspension compresses (moves inwards) when the vehicle encounters changing circumstances on the road or track. In performance driving or racing scenarios, the ability to adjust compression damping can enhance handling characteristics. It's important to balance the rebound with the compression adjustment. You can stiffen the rebound / compression settings to reduce body roll during cornering, improve responsiveness, and maintain tire contact with the road for better traction. But also fine-tune the ride comfort by controlling the compression. This set of suspension also includes, where applicable, camber-adjustable front Top Mounts and solid rear Top Mounts. The camber adjustment will offer you more wheel adjustment and allow this geometry to be altered to transform front -end grip. Springs are included.

Set of MONOTUBE coilovers, 2WAY adjustable in rebound, compression and ride height. This set includes external reservoirs and, where applicable, camber-adjustable front Top Mounts and solid rear Top Mounts.
