Full Rear end restoration on this wide body Z3, such a lovely car!
Need a rear end refreshed to the same standard?
The Z3's have a factory defect where the rear differential mount is spot welded to a cross member in the chassis rails, they slowly pop the spot welds from the rail and the boot floor, so the only way to fix it properly is brace the whole area with thicker metal and fabricate a new heavy duty mount! Plug weld through the boot floor with a connecting plate from each main chassis rail.
