The KYOSTAR Performance Lowering Spring Kit is an aftermarket suspension component set listed for 2017–2023 BMW G30 5 Series sedan applications, including the 530i, 540i, and M550i. Exact compatibility must be verified against the vehicle's drivetrain, suspension configuration, and axle load specifications.
Featuring a red coil spring design, this kit is intended for vehicle lowering and suspension customization applications. The supplied product image shows four coil springs with different winding configurations, consistent with a front and rear suspension spring arrangement.
Lowering springs are commonly used in automotive suspension modification projects to achieve a lower vehicle stance. Actual ride height changes, suspension characteristics, and ride comfort depend on the vehicle's factory suspension setup, spring specifications, dampers, and installation.
For automotive aftermarket distributors, BMW suspension specialists, professional tuning workshops, and performance parts resellers, KYOSTAR offers this product as a suspension component option for the BMW G30 platform, subject to fitment confirmation.
This lowering spring kit is listed for selected BMW G30 5 Series applications, including 530i, 540i, and M550i models. Vehicle-specific spring compatibility depends on axle weight, drivetrain, suspension equipment, and factory spring specifications.
Because the listed vehicles have different powertrains and available suspension configurations, buyers should not assume that all models use interchangeable springs. Confirm the complete spring specifications and intended vehicle application with KYOSTAR before purchasing.
Professional suspension installation and a four-wheel alignment are recommended.
