How to Install BMR Weld-on Tubular Subframe Connectors - Hammertone (94-04 Coupe) on your Ford Mustang

NOTE: Although this installation can be performed with a hydraulic jack and stands, a 4-post service lift is recommended. 

INSTALLATION:

1. Lift vehicle and support with the suspension loaded. If not using a lift, position front tires on ramps and support rear end using jack stands.

2. Locate the seatbelt bolts protruding through the floor pan. Using 17mm socket, install the supplied BMR seatbelt brackets as shown in IMAGE 1 using the supplied nuts and washers. Leave nuts loose to allow the bracket to slide side to side for subframe connector alignment. There is a left and right bracket; the driver’s side has the square notch off-centered.

3. Start with the driver’s side connector. Lift subframe connector into place and support with stands. Using a permanent marker, trace all weld points onto the frame. Positioning and weld points can be seen in IMAGE 2. Remove subframe connector. 

4. Using a sander, prep all the welding areas on both the frame and subframe connector. It is important to remove all powder coat, paint, and undercoating to allow a spatter-free, strong weld.

5. Reposition the subframe connector into place and weld all weld points.

6. Repeat steps 3, 4, and 5 for the passenger side.

7. Once both sides have been welded, wire wheel all the weld areas and then paint with a rust preventative paint.

8. Using 17mm socket, tighten the seatbelt bolts.

9. Lower vehicle.
