AST Suspension BMW X3M (F97) / X4M (F98) Adjustable Lowering Springs

These adjustable lowering springs from AST Suspension are made specifically for the BMW X3M (F97) and X4M (F98) models. They allow you to fine-tune your vehicle's ride height, giving you the ability to achieve a more aggressive stance and potentially improve handling characteristics. If you're looking to dial in the perfect look or want to lower your M-series SAV for better cornering, these springs are a solid option.

AST is known for making well-built suspension components, and these springs are no exception. They are constructed from high-tensile spring steel, which is chosen for its strength and ability to maintain its shape over time, even under the stresses of spirited driving. The adjustable spring perches allow for a range of lowering from approximately 10mm to 30mm, giving you flexibility to set your ride height precisely where you want it. This adjustability is a key feature, as it lets you compensate for different wheel and tire setups or simply achieve the exact aesthetic you're after. They are designed to work with your vehicle's factory dampers, making them a more straightforward upgrade than a full coilover system.

When installing these springs, it's important to have your vehicle's alignment checked and adjusted afterward to ensure proper tire wear and optimal handling. Because these are adjustable, you can set the initial ride height and then have the alignment performed. This is a significant upgrade for owners who want more control over their vehicle's appearance and performance dynamics. You'll want to ensure you have the necessary tools for spring compression and installation, and it's always a good idea to consult your vehicle's service manual or a professional mechanic for the correct procedures.
