E46 Rear Suspension

The Central "C" Link rear suspension on the E46 is almost identical to the E36 with some minor modifications:

• Upper Transverse Control Arms (Lateral Links) are made from aluminum.
• The Subframe (rear axle carrier) is of tubular steel construction.
• The differential is mounted to the subframe with a hydraulic mount.
