Engineered for track use, these coilovers feature 3-way adjustable damping, allowing precise tuning for rebound, high-speed compression, and low-speed compression. The rebound adjustment offers 12 positions, while the high-speed compression also has 12 settings, and the low-speed compression provides 14 settings, all accessible via external canisters. This independent adjustability ensures optimal handling, stability, and ride quality under various driving conditions. Constructed with durable materials, these coilovers are built to withstand rigorous track environments and deliver consistent performance.

Designed to fit 2005-2011 Ford Focus ST models with the 2.5-liter engine, these coilovers are a direct upgrade for enthusiasts seeking enhanced handling and customization. They are ideal for track days, spirited driving, or performance tuning, offering adjustable ride height and damping settings to suit individual preferences. Installation is a bolt-on process, compatible with the factory mounting points, and no additional modifications are typically required. The kit includes the coilover units and necessary mounting hardware, providing a comprehensive solution for suspension upgrades. Suitable for both street and track use, these coilovers help maximize the vehicle’s dynamic capabilities.
