Flatout GR40 Coilovers for 2007-2013 BMW X5

The Flatout GR40 Coilovers are engineered for BMW X5 drivers who want a suspension system that delivers both daily driving comfort and true rally-inspired performance. With an adjustable 1–3 inch lift over stock ride height, the GR40 provides the added ground clearance required for trails, rallycross events, and overland setups — while maintaining a refined ride on pavement.

Built with inverted front shocks for maximum strength and stability, combined with external reservoir rear shocks for improved cooling and endurance, the GR40 is designed to handle aggressive use without compromise. Whether you’re exploring off-road terrain or building a capable adventure-ready SUV, this system provides a complete, high-performance solution.
