AST Lowering Springs For BMW Z4 35i/35is 04/2009-01/2019, Front 30 , Rear 25

The AST Lowering Springs for BMW Z4 35i/35is 04/2009-01/2019 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 cold-coiling technology on the renowned Wafios coiling machines, these springs ensure consistent quality and durability. Designed specifically for the BMW Z4 models within the specified production years, this set offers a tailored fit that integrates seamlessly with your vehicle’s suspension system.

By lowering the front by 30 mm and the rear by 25 mm, these springs improve handling characteristics, reduce body roll, and contribute to a more aggressive stance without compromising ride comfort. The progressive spring design balances performance and usability, making it suitable for both daily driving and spirited road use. The use of premium materials and advanced manufacturing processes guarantees longevity and resistance to fatigue, supported by a lifetime warranty against breakage.

The AST Lowering Springs are a direct replacement for the original equipment manufacturer (OEM) springs, ensuring ease of installation and compatibility with existing suspension components. Their application spans a wide range of vehicles, but this particular set is optimized for the BMW Z4 35i/35is models produced between April 2009 and January 2019, providing a reliable upgrade that meets professional standards.

Notes

For vehicles already equipped with standard lowering springs, the effective lowering will be reduced by the amount of the existing lowering.
