AST 5300 Series Coilovers Ford Fiesta Zetec ST

AST is well-known for building serious suspension components for track use. If you're looking to get the absolute most out of your Ford Fiesta Zetec ST on the track, the AST 5300 Series coilovers are designed to help you achieve that goal. These aren't just about lowering your car; they offer a deep level of adjustability that lets you fine-tune how your suspension behaves under extreme conditions.

What sets these coilovers apart is the 3-way adjustability, which means you can independently control the rebound (how the shock returns after compression) and both low-speed and high-speed compression (how the shock compresses over bumps and during cornering). This is managed through external reservoirs, giving you distinct feedback with each adjustment. The inverted strut design is built to handle the significant side loads and braking forces common in racing. You also have the flexibility to change spring rates, allowing for further customization. With 12 distinct positions for rebound and separate controls for low and high-speed compression, you can dial in everything from body roll during hard cornering to responsiveness and tire contact for maximum traction.

This kit also includes camber-adjustable front top mounts, which allow you to alter your front-end geometry for improved grip. Solid rear top mounts are also included where applicable. These adjustments allow you to fine-tune critical aspects of your vehicle's handling, making them a solid option for dedicated track use.
