HONDA K Series - Manual (Page 9)

Step 3: Drill six holes to support the bottom of the subframe using a 5/16”
drill bit. Use the six supplied 5/16” bolts with plates to fasten the subframe to the car
on the lower side. The plates will go inside of the car to give the floor panel extra
support. After the six bolts are in place and tightened, tighten the two large subframe
mounting bolts on top of the frame. See photos.
Your subframe should now be attached to your Mini.
