The AST Suspension 2-WAY MOTORSPORT SUSPENSION is primarily engineered for track enthusiasts, allowing separate adjustment of compression and rebound 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.
