BMW 5 Series F07 (2010-2017)

This is an OEM INA Idler Pulley, also known as the roller pulley or deflection pulley. The idler pulleys are known to be the primary sources for 'belt squealing'. The pulley is also encased in rubber which will crack over time. If left without service the rubber could fail completely, chucking the belt and leaving you stranded. Replacement is a very simple procedure and can be done anytime the fan is off the engine (belt replacement, water pump service, alternator replacement, etc).

Apex ARC8 18x9.5" Square Wheel Set

If you're tracking your BMW you should absolutely have stickier rubber on wider wheels. Most BMWs have a staggered wheel set with a narrow front wheel that results in understeer. Adding a wider wheel will get you more rubber where it counts - reducing understeer and improving initial turn-in. Square wheel sets of the same size and offset also allow you to rotate tires around to get the most life out of pricey track tires. We have put this wheel set together using four APEX 9.5" wheels in a ET22 offset. A 9.5" wheel allows for 265-285 performance or R-comp tires.

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.
