E46 Models
Rear Suspension
The design of the E46 rear suspension is based on the E36 "C" arm type. However, all
components of the suspension are new and designed to suit the E46 for:
• Comfort and convenience
• Handling and stability
• Noise reduction
The sub frame is a new design employing steel tubes and metal sections. It is more rigid
than the previous sub frame. This provides a stable platform for the rear suspension to
work from. The differential is mounted to the sub frame using a hydraulic mount. The sub
frame is mounted to the body at four vibration absorbing rubber mounts.
The upper transverse control arms are made from cast aluminum for weight saving.
