AST Lowering Springs For BMW Z4 18i/20i/23i/28i/30i 04/2009-01/2018, Front 30 , Rear 25
Description
The AST Lowering Springs for BMW Z4 18i/20i/23i/28i/30i (04/2009-01/2018) are engineered to enhance your vehicle's driving dynamics by lowering the center of gravity while maintaining a high level of comfort. Manufactured with precision using the finest Wafios coiling machines, these cold-coiled springs provide a reliable and durable solution tailored specifically for your BMW Z4 model.
Designed as a direct replacement for the original equipment manufacturer (OEM) springs, the AST Lowering Springs feature a progressive spring rate that balances performance improvements with ride quality. By lowering the front by 30 mm and the rear by 25 mm, these springs improve handling characteristics, reduce body roll, and enhance stability during cornering without compromising everyday comfort.
Constructed from premium materials and subjected to rigorous quality control, the AST springs ensure long-lasting performance and resilience. Their extensive application range, covering over 2500 vehicle models since 1966, reflects the brand's commitment to compatibility and excellence. Additionally, the springs come with a lifetime warranty against breaking, underscoring their reliability and the manufacturer's confidence in their product.
When installing on vehicles with standard lowering, please note that the indicated lowering measurements may be reduced by the amount of the existing standard lowering. This ensures that the final ride height meets your expectations and maintains optimal vehicle dynamics.
