Independent front and rear suspension is used, with Macpherson struts at the front and a semi-trailing arm design for the rear.
The front suspension was upgraded to use dual links at the bottom of the strut, as first seen on the E23 7 Series. This increases steering offset while cornering, to improve steering feel. Double-acting shock absorbers, coil springs and a front anti-roll bar are used.
The rear suspension is mounted on a delta beam that is connected to the body with three screws in rubber bearings, that have longitudinal play. Some models have a rear anti-roll bar.
The steering on most models is a speed-dependent recirculating ball power steering system made by ZF Friedrichshafen. The 518i has a Gemmer steering system with a double enveloping worm gear, also made by ZF.
Wheel sizes are 14-inch (16-inch for the M5 model) or 390mm Michelin TRX. All rims have 22 mm positive rim offset.
