The fabricated subframe is attached to the body by four bolts. The inside bolt (3 on illustration) on the left side of the subframe is the master bolt to ensure the subframe is in its correct lateral position. The subframe also provides attachment points for the fuel tank straps and rear suspension lateral links. The anti-roll bar attachment points are on the top of the subframe and cannot be seen on the illustration.
