APEX ARC-8 19" Staggered Wheel Set -- 19x8.5" / 19x9.5"

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 concave face than the fronts, emphasizing the RWD chassis and adding some muscularity to the stance.

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.

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.

Turner Motorsport recommends flushing and replacing your manual transmission and differential fluid regularly to ensure proper component wear and prevent costly issues in the future. Refer to your owner's manual for specific intervals for flushing and refill.
