Construction & Design:
The AST 5100 Comp Series Coilover Kit features a monotube damper design, which eliminates aeration and foaming common in twin-tube shocks. This design choice results in more precise and responsive valving, enhancing your vehicle’s handling feedback and control. The large piston within the monotube damper allows for superior adjustability of rebound damping, giving you the ability to dial in the suspension to your exact preferences.
Front and rear coilover assemblies integrate springs and dampers into a single unit, simplifying installation and improving suspension response. The inclusion of camber-adjustable front top mounts enables fine-tuning of wheel alignment, allowing you to optimize front-end grip and cornering performance.
Installation & Fitment:
This coilover kit is designed as a direct fit for the specified Toyota 86, Subaru BRZ, and Scion FR-S model years, utilizing factory mounting points and hardware. The comprehensive design includes all necessary components for a straightforward installation process. Adjustments to rebound damping and ride height can be made without removing the coilovers, allowing for convenient tuning to suit your driving style and conditions.
