Description

The AST 5300 Comp Series Coilovers are a high-performance, 3-way adjustable suspension system designed for track use while maintaining an ideal road balance for daily driving. This coilover kit allows for precise control over the vehicle's dynamics through separate adjustments for rebound, low-speed compression, and high-speed compression. The system includes remote reservoirs (canisters) for enhanced performance and adjustability. Its inverted strut design is engineered to withstand substantial side loads and braking forces, ensuring stability and consistent handling. Both front and rear dampers feature a monotube coilover design, which provides greater damping power and responsiveness due to a large piston and the absence of aeration or foaming. The kit includes springs with adjustable rates, allowing for further tuning. Where applicable, camber-adjustable front top mounts and solid rear top mounts are also included, offering additional wheel adjustment and the ability to alter geometry for improved front-end grip. These coilovers are rebuildable, ensuring long-term serviceability.
