I’ll give them a 5-star rating for their appearance and quality. However, the installation process is unique to the Ineos Grenadier. There isn’t really a straight reference point to guide you. If you don’t have a construction laser, I recommend setting the fender plates in place. Measure the distance from the front above the headlights and from the side of the hood seal. Check the reveal on all sides. Then, place some weight(s) on top of the fender plates to prevent them from moving. Finally, run a strip of blue painters tape along the front edge and outside edge (above the wheel arch) of the flare plates. This will provide you with a square reference point for installation.
I then used duct tape to secure the fender plate to the blue tape edge above the wheel arch. This allowed me to stand the plate on edge without it moving. I removed the tape from the 3M adhesive and then laid the fender plate back down between the blue tape lines. This method is the best way I could find to keep the plate square while adhering to the fender. Press it down around the ends and edges. Finally, I placed some 20lb weights back on top of the fender plates.
