If you need to mount the OEM Euro Spec Harness to your M4 or M4 GTS, the RKP M4 GTS harness mounts are a necessity. The harness mounts are of the highest quality, so you’ll never have to worry about durability or strength. Optional ring bolts will be needed to strap the harness to the vehicle interior; each set of ring bolts comes with 12 pieces (6 ring bolts per side).
