APEX light alloy wheels are the next evolution in flow-forged wheel technology for BMWs. Flow-forming is a semi-forging process that produces a wheel typically stronger than a traditional cast wheel yet is still light weight. The wheels are around 10lbs lighter per wheel than a comparable factory wheel! That's reduced unsprung weight that improves all aspects of performance. The spokes and barrel have been designed to allow generous clearance for big brakes. In other words, these wheels are very impressively engineered and look great too! The design is based on classic motorsport themes that blend with BMW styling and appearance. These wheels look right at home on many BMW models. Multiple color and profile options allow you to set just the right look and stance for your car. As well as being pleasing to the eye these are very strong and functional wheels that are at home on the street as well as the racetrack. Don't let the price fool you - these wheels are high quality, high strength, and in high demand.
All APEX wheels are the BMW standard 5/120 bolt pattern and with a 72.6mm center bore. They are a direct fit many BMW models and may fit other models with a specific wheel spacer. The original BMW center cap, TPMS sensors, and original lug bolts are all carried over from your original wheels (wheel bolts may vary if spacers are used). They come in a wide variety of diameter, width, and offset combinations which gives you multiple fitment and application opportunities. For street use we generally recommend a staggered setup with a rear wheel slightly wider than the front. For track and racing applications a square setup is desired with the same width in the front and rear. Wheel offsets may also vary based on the clearances and stance you wish to achieve. Refer to our image gallery for inspiration. If you'd like more input give us a call or e-mail and we'd be happy to go over the many options with you.
Note: careful consideration of wheel width, offset and tire sizing must be observed when choosing and installing larger wheels. Adding larger wheels may lead to rubbing on suspension components or bodywork. Wheel spacers, new alignment settings, inside fender modifications, or other adjustments may be required.

The Bilstein B8 Performance Plus Kit includes two front struts and two rear shocks. These shocks are for use with lowered springs such as from H&R or Eibach. We do not recommend that you use them with any factory spring, including factory sport package springs. With the increased damping rates from stock you will have much more control over body motions. These will give a much more buttoned down and taut feeling with lowering springs compared to stock shocks.
These shocks fit the following BMWs:

The B16 PSS9 coilovers offer a stiffer spring rate than stock and a lower ride height for less bodyroll and better handling. These are among the easiest coil over kits on the market - no special mounts required (works with stock mounts and sway bar links), larger adjustment knob allows for easy shock damping changes, and coil over spanner wrenches included for easy height changes. Bilstein backs up their technology with a limited lifetime warranty. TUV approved for fitment, safety, and quality!
Bilstein's monotube shock dampers in the PSS9 offer 9 precise settings for compression and rebound. A new setting is just a click away, allowing you to set a ride and handling combination that works for your setting. Instead of offering too many shock settings that you're never going to use, Bilstein has chosen ten optimal damping curves from a smooth street setting (P9) to an ultra-stiff track-only setup (P1). Shock changes are made from an easy-to-use over-sized adjuster knob.
Ride height adjustments are done from perches that ride on each shock body, which are zinc coated for excellent wear and corrosion resistance. You can set the ride height between 0.5 to 1.3 inches lower than stock ride height. Springs are progressively rated so their initial compression rating is quite soft and then becomes stiffer as the spring compresses. These are stiffer than most coil over kit manufacturers and the results of Bilstein's extensive testing on the German Nurgburgring and Autobahn.
The fitment of these is just like a standard shock and spring package. The front struts and rear shocks are compatible with the stock strut and shock mounts. You can re-use your own or choose a mount with additional features. Because the Bilstein design keeps the sway bar tab in the original location, you can re-use the stock sway bar links. Using the stock mounts keeps the cost and complexity down and allows for TUV certification. You can also be assured of the stock mount's quiet and long-lasting performance. The assembly of the front strut is the same as a the factory strut. In the rear, ride height is made by an adjustable spring perch that sits under the rear spring. Install instructions and diagrams included.
If you're looking for a supremely capable and high quality suspension, then look no further than the Bilstein PSS9. It combines all of the best German engineering with real-world development, and a lifetime warranty.
Fitment note: this system works only on cars not equipped with the factory EDC electronically adjustable shocks.
