Product Description

The H&R 50490-4 Sport Spring Kit is engineered specifically for the 2007-2013 BMW 335i Sedan (E90) and Convertible (E93) with the N54 or N55 3.0L turbo inline-six in rear-wheel-drive configuration. The kit delivers a 1.3" front and 1.2" rear drop with H&R's signature progressive spring rate design, lowering the chassis for an aggressive stance and tighter fender well gap while preserving everyday ride comfort. Body roll, brake dive, and acceleration squat are all dramatically reduced, sharpening the 335i's handling without sacrificing daily-driver compliance.

Every spring is cold-wound in Germany from H&R's proprietary 54SiCr6 spring steel rated at 290,000 PSI tensile strength, then shot-peened to extend service life by over 200%. ISO 9001 certified and TUV approved manufacturing ensures consistent spring rates and dimensional accuracy across the set. Aftermarket shocks designed for higher spring rates are recommended, and a suspension alignment is required after installation. Backed by H&R's lifetime limited warranty.
