For reference: first spacer installation. super easy. I took the tires off, put on red Loctite spacers and torqued them to what I believe to be 100 ft/lbs. Then he made the same eyelets. I was with them last week. For reference, I have 275/65/r18 tires. They didn't used to rub, but now they rub a little. It remains to remove the lower front inner wall of the wing. A kind of front fender Iono. Now I can see my tires in the rearview mirror.
