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.

Turner Recommended Setups: 
Aggressive Square Setup (Front + Rear) for non-M model E46 325/330
Aggressive Front Wheel for E46 M3 / Z3 M / Z4 M


All APEX wheels are the BMW standard 5/120 bolt pattern and with a 72.6mm center bore. They are a direct fit to most any 1-series (E82), 3-series (E36, E46, E90, E92, F30), Z3, and Z4-series BMWs. 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.
