BMW Spring & Shock Packages (BMW Performance and More) for BMW 3 Series E90 (2006-2011)

Your 335i is capable of super-serious speeds - make sure your suspension matches its capability! The stock 335 suspension shares many of its components with the regular 3-series models. Given the power output differences you should have a suspension that is able to handle the additional power. This package of H&R sport springs and Bilstein shocks will plant the 335 in the corners much better than stock.

H&R Sport springs lower the ride height as much as 1.3" in front and 1.2" in the back and stiffens the spring rate. Both combine to lower the car's center of gravity and reduce the amount of bodyroll in corners. The springs are progressive rate so their initial stiffness is actually very compliant and it becomes stiffer as the spring is compressed. This is great for street cars that see bumps and potholes where suspension compliance is key. Overall, they are about 30% stiffer than the stock original springs. Lowering amount will be less if replacing the factory sport suspension.

We use Bilstein shocks as the dampers and they feature Bilstein's patented and innovative valving system. With this system, small bumps and impacts are absorbed as they should be. But the shocks stiffen for cornering and other suspension motions. It's the best of both worlds as the shock self-adjusts based on suspension motion. These fit with the stock strut and shock mounts, making for an easy and clean install.
