This suspension package for the 1998-2002 Z3 M Roadster and M Coupe will lower the ride height and stiffen up the suspension for less bodyroll and improved balance. They key to taking corners faster and reducing bodyroll is to firm up the suspension and we start with the shocks and springs.
H&R Sport springs lower the ride height 1.3" front and rear 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 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.
