Description

Part #: ASTALS-21-003

Droplinks, also known as swaybar links or stabilizer-bar links, are the components in a vehicle's suspension system that connect the sway bar (anti-roll bar) to the suspension components. They help control body roll and improve stability during cornering and over uneven road surfaces. AST Droplinks have ball joints at both ends to allow for adjustment between 330mm and 370mm, while maintaining a secure connection. This adjustment has a crucial role in enhancing a vehicle's handling and reducing body sway, contributing to a smoother and safer ride. Set of 2 AST Droplinks, M10, adjustable from 330mm to 370mm. Other sizes available.

Set of 2 Droplinks, M12, adjustable from 330mm to 370mm.

MIA's Description

The AST Adjustable Lowering Springs for BMW G80 M3, G82 M4, G83 M4, and G87 M2 allow for fine-tuning of ride height while maintaining OEM comfort. They are crafted from premium high-tensile chromium-silicone wire, undergo cold-winding, heat-treatment, and shot-peening, and are phosphate-treated and powder-coated for corrosion resistance. These springs are compatible with BMW's Electronic Damper Control (EDC) system, offer progressive spring rates, and lower the vehicle by 20-46mm in the front and 10-36mm in the rear.
