BMW Z4 M Roadster S54 (2003-2008)

Bilstein has teamed up with Eibach to offer matched shock and spring packages. These Eibach springs are mated to a special set of Bilstein shocks to deliver a sporty and taut ride with as little impact on ride comfort as possible.

The Pro Kit uses an Eibach Pro Kit spring with Bilstein's Sport shocks and struts. Instead of taking parts from different manufacturers, Bilstein has tested the performance of the Eibach spring and tailored their shocks to be a true match for the new spring rate and ride height. This is known as a matched shock and spring and very few tuning companies take these extra steps. Eibach springs tend to be softer overall than most other aftermarket springs, which ensures the ride stays close to a stock comfort while still giving you a lowered stance and improved handling. 

Bilstein B12 Features: 

• Precise response and excellent driving performance
• Springs and shocks road tested and fine-tuned to complement one another
• Bilstein Monotube/Inverted gas pressure technology
• TUV certified
• Made In Germany
• Average Lowering of 25 to 40mm

Most cars don't need coil overs to improve their handling and bodyroll. For most drivers, simply replacing the shocks and springs with performance versions will meet their goals. If your shocks need replacing, and you felt the handling could be improved a little bit, this is an excellent performance suspension for you.

This item fits the following BMWs:
2006-2008 E85/E86 BMW Z4 M Coupe, M Roadster

Offset (mm):22

Weight (lbs):19.2

Profile:Concave

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.

APEX EC-7 18" Staggered Wheel Set -- 18x8.5" / 18x9.5"

This set of 8.5" and 9.5" ARC-8 wheels is an easy staggered fitment for the E46 M3 and Z4M models. These are a direct fit with no spacers or fender rolling required. We use an 8.5" ET35 on the front and a 9.5" ET22 on the rear. These are only slightly wider than the stock sizes. The rear wheels have a deeper curve to the spokes than the front wheels, emphasizing the RWD chassis and adding some muscularity to the stance.
