APEX ARC-8 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" ET38 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.

It is recommended for any vehicle where the boost pressure has been increased by an ECU software upgrade and for unmodified vehicles operating in warmer climates, as a solution to the many failures that have occurred, where the original rubber diaphragm splits, which causes a loss of boost pressure. Unfortunately the failure doesn’t always result in a check engine light as the valve can still be blown open by the boost pressure, so you may not be aware that you are losing power due to this.

Our alternative is a fully engineered solution offering significantly improved reliability. Our valve is piston based with no diaphragm to fail, and of all aluminium construction. It replaces the original unit with a pressure/vacuum operated piston valve that still also retains the desirable OEM ECU control over valve actuation.

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 non-M E90/E92 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" ET33 on the rear. The rear wheels have a deeper concave face than the fronts, emphasizing the RWD chassis and adding some muscularity to the stance.
