E85 Z4 2.5/3.0/3.0i/3.0si H&R/Bilstein Sport Suspension Package

Product Details

Set your Z4 up for the corners with this shock/spring upgrade package. The Z4 can be a fun car but you can easily bring the handling up a notch with this package. By lowering the ride height and using a stiffer spring it can transform the behavior of the car in the corners. There will be less bodyroll and better balance, allowing you to carry more speed through the twisty sections. And there is almost no downside thanks to the ride attributes of this suspension.

H&R Sport springs lower the ride height by up to 1.5" in front and 1.25" 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.

We use Bilstein Sport 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.
