AST 21-23 BMW G8X M3/M4 xDrive 5100 Clubracing Suspension

This AST 5100 Clubracing Suspension kit includes the complete set of front and rear coilovers specifically developed for the 2021-2023 BMW G8X M3 and M4 models equipped with xDrive all-wheel drive. These are not just basic lowering springs; they are a full coilover system designed to give you significant control over your vehicle's ride height and damping characteristics. If you're looking to dial in your suspension for track days or spirited driving, this kit offers the adjustability and performance you need.

The 5100 Clubracing series from AST is built with performance in mind. Each coilover features a monotube design, which generally offers better heat dissipation and more consistent damping compared to twin-tube designs, especially under demanding conditions like track use. The damping is adjustable, allowing you to fine-tune the compression and rebound to suit different track surfaces, tire compounds, or driving preferences. You can adjust the ride height independently of the spring preload, giving you the flexibility to achieve your desired stance and corner balance without compromising suspension travel. The internal valving is tuned for a sporty feel, providing improved body control and feedback without being overly harsh for street driving.

When installing a full coilover system like this, it's important to consider that a professional alignment will be necessary after installation to ensure proper geometry and tire wear. While the coilovers themselves are designed to fit directly onto the factory mounting points, the adjustability means you'll want to get the alignment dialed in by a professional. This kit is a substantial upgrade for the discerning BMW owner who wants to extract the most performance from their G8X M3 or M4.
