BMW M5

Chassis
The E39 M5 uses aluminium-intensive MacPherson strut front suspension and multi-link rear suspension, as per the other V8 models of the E39 5 Series range. However, several changes were made by BMW M. Reduced spring height, 23 mm (0.9 in) lower. A specific shock valving, thicker front and rear anti-roll bars, polyurethane auxiliary springs, and steel balljoints.

Although the six-cylinder E39 models use rack-and-pinion steering, the M5 (and other V8 models) retains the recirculating ball steering system, as used by previous generations of the M5. A quicker steering ratio of 14.7 was used, compared with 17.9 for other V8 models. It featured a Servotronic vehicle-speed-sensitive power assist which provides two levels of resistance controlled via console mounted Sport button. The Sport button also adjusted the electronic throttle butterflies for more sensitive response.

Brake discs (rotors) are a “floating” two-piece design (except for U.S and Canada models), for reduced risk of cone distortion. Their lower unsprung weight improves ride quality and traction on bumpy surfaces as well. The front discs are 345 mm (13.58 in) in diameter and the rear discs are 328 mm (12.91 in) in diameter. mazda wallpapers, download here, volvo wallpapers, BMW M5 wallpapers, jeep wallpapers
