H&R Sport Spring Kit | BMW 428i/435i/430i Cabrio F33 (14+) (28878-4)

The H&R Sport Spring Kit for BMW 428i, 435i, and 430i Cabrio F33 models is a performance suspension upgrade designed to improve handling and aesthetics. Crafted with progressive spring rates, these springs lower the vehicle's ride height to reduce fender well gap, resulting in a more aggressive stance and streamlined profile. The springs also lower the vehicle's center of gravity, which enhances stability and reduces body roll during cornering. Built from high-quality materials, the kit offers a balance of sporty performance and ride comfort, making it an ideal choice for enthusiasts seeking both style and improved driving dynamics.

This spring kit is compatible with BMW F33 Cabrio models from 2014 onward, including various engine configurations such as the 428i, 435i, and 430i. It serves as a direct replacement for factory springs, providing a bolt-on installation that does not require additional modifications. The lowered stance not only enhances visual appeal but also contributes to better aerodynamics and gas mileage. The kit includes all necessary components for installation, making it suitable for street-driven vehicles focused on improved handling and a sportier look.
