Description
Are you the most dedicated enthusiast on the race track? Elevate your racing game to a championship level by using all options that AST 3-WAY MOTORSPORT SUSPENSION has to give. Challenge your vehicle by adjusting the rebound and the low- and highspeed compression adjustment 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 three critical aspects of your vehicle’s suspension. You can adjust the rebound, means you can control the return to extension of your dampers. 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. With this kit you can adjust low- and high speed compression adjustment separately. Low-speed compression refers to the suspension reacts to gentle and gradual compression forces. High-speed compression addresses rapid and forceful impacts. 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.
