THE Rover 75 employs MacPherson strut suspension up front in combination with a perimeter-type front subframe and an L-shaped aluminium lower arm. A double ball-jointed 24mm anti-roll bar is fitted. Rover says much research went into the 75's rear suspension design, with the basic principles of the rear-drive BMW Z-axle eventually applied to the front-drive 75. Each side of the Z-axle has an integrated trailing arm and hub carrier, plus upper and lower transverse arms and a 19mm anti-roll bar.
