When you take the beauty rings off, and install the FRP beadlock, is it a simple swap, ring for ring? you don't need to air the tire down and mess with the bead or anything do you?
Yes you have to air the tire down and remove beauty ring. Then you have to pop the bead over onto the locking side of the wheel. You'll see a grove in the wheel were the beauty ring sat down into. That's were the tire bead needs to sit. I have a tire machine so moving the bead was easy for me.
The reason a chased all the holes was because there was thread lock residue from the beauty bolts and a bit of sand from having the wheels powder coated(I didn't care for the black).
It's a pretty simple install, just takes some time to do them. I think there is a YouTube video or write up that I have seen somewhere on how to do it. The FRP rings come with instructions. I didn't use them, it's the same as mounting up a race beadlock and we have done 1000's of them.
Here a tip that we use, put WD-40 on the bead before installing to beadlock. It helps the tire move around as your tightening it all down.
