BMW Spring & Shock Packages (BMW Performance and More) for BMW 3 Series E46 (1999-2005)

The E46 3-series can really benefit from a slightly firmer suspension. The stock shock and spring package is a bit too soft and mushy with a lot of bodyroll. Even the factory sport suspension was a marginal improvement. If you have been left wanting more from your stock suspension, this is the perfect upgrade. In this E46 shock and spring package we paired H&R Sport springs with a set of Bilstein sport shocks and struts to deliver a package with near-stock levels of comfort but with stiffer springs that improve handling and lower the ride height for better aesthetics.

H&R Sport springs lower the ride height by up to 1.4" in front and .75" 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.

Ride height varies by stock suspension:

E46 standard suspension: F: -1.4: / R: -0.75"
E46 sport suspension: F: -0.75" / R: -0.25"

Dinan Performance Shocks and Springs are matched to your BMW's chassis and suspension components to deliver better handling and looks without sacrificing ride quality. Dinan BMW spring rates are slightly stiffer than stock and dialed in to reduce bodyroll. A stiffer suspension makes the car more fun to drive and the lower ride height improves the looks by reducing wheel-fender gap. Specially valved Koni shocks are matched to the springs to precisely dampen body motions and control the ride. The shocks are adjustable between two settings for normal street and aggressive street use.
