AutoStyle lowering springs suitable for BMW 3-Series G20 330D xDrive 7/2019- 40/40mm Lowering springs lower the center of gravity of your car, resulting in improved handling, reduced body roll and providing a sporty look. AutoStyle aims to develop high quality car parts without sacrificing ride quality and comfort. Our lowering springs are progressive rate springs, which becomes stiffer when pressure is increased. This aids in improved responsiveness when cornering and decreases rollover risk. Features: - Sporty look and improved aerodynamics - Progressive spring rate - Improved handling - Reduced body roll Manufactured in The Netherlands, these lowering springs are phosphated and have a special epoxy coating to protect against corrosion. Assembling lowering springs requires knowledge and special tools. It is also necessary to align your car afterwards, we therefore advise to have the spring set assembled by a professional workshop.
