H&R is the originator of the true coil-over system for the street and continues to lead the market. The H&R Street Performance Kits use black anodized aluminum front struts that reduce unsprung mass by upto 40% depending on application. Each mono-tube gas shock is specifically engineered to work smoothly with the progressive springs. H&R units are hand-assembled in Germany under rigid ISO 9001 and German TÜV standards.

"I can't tell you what a win/win situation it is installing these coilovers. The ride is better, the handling is better, the car looks better. The only drawback was a slight gain in weight, very small, but the BMW OEM suspension is cast aluminum and quite light. The total difference is about 6.6 pounds total.
With the car jacked up, the front ride height can be adjusted without removing the wheels (just turn the wheels). The Variant 3 kit has adjustable ride height, compression, and rebound. Compression adjustment can be found at the bottom of the strut, rebound is adjusted at the top of the rod. The adjustments can be measured by a series of clicks.
The KW kit just exudes quality. No fitment issues whatsoever, everything fits perfectly. These guys did their homework, this is the only way I would lower my car. Do yourself a favor, don't just buy springs to drop your car."badfish on M3post.com
The Variant 3 represents state-of-the-art technology for the experienced driver. Separate and independent compression and rebound damping options allow a individual suspension set-up. The 3 individually adjustable components, allow adjustment of the compression of the damper in the low-speed range, while the high speed set-up, so decisive for driving comfort, has been preset by KW engineers.
The unique low-speed pressure adjustment is the decisive feature of the Variant 3. In this absorption area the handling of the vehicle is greatly influenced. An increase in the damping force supports the vehicle even during compression, thereby preventing pitch, roll and notably improving cornering. The compression characteristics are adjusted utilizing a new, patented valve at the lower end of the damper casing.
