FC RX7coilover install advice - grind the front knuckle here so that you can use the slotted hole adjustment. If you cant grind it, the lower bolt is pretty tight, however you can still tap the bolt in place with a hammer and get driving safely if you are without a grinder (as shown in the pic)
alternatively you can grind the aluminum on the front lower mount like this so that the lower bolt is buttery. We will re profile future production lower mounts at the factory to improve ease of install.
