What does the JJ stand for on a Rim or Wheel?

The J or JJ signifies the dimensions of the beads lip, or you could also call it the shape of the flange.  The difference between a J and a JJ rim is mostly only in the radius of the flange.

JJ = 18.0mm high x 13.0mm wide, with a 13.0mm radius
J = 17.5mm high x 13.0mm wide, with a 9.0mm radius

I bought my first Subaru back in 2005, it was a 89 Brumby, flair red. I lifted it, fitted Kumho 27″ MT’s. After a while I swapped the dual carb EA81 it had with an EJ22 bolted on a custom gearbox which used EJ D/R casing, EA82 5sp low range and an RX centre locking diff. Once I sold the Brumby I got a 83 Leone. Converted it to 4WD, put the Kumho’s on it, added a 5sp and drove it like I stole it. I then upgraded to a 99 Outback. It was hail damaged so I repaired it myself. I fitted it out with some storage and a mattress. I now have a 87 Brumby that I’ve resprayed with two pack urethane in Waratah Red. I am planning to fit an EJ with PT gearbox and a little bit of lift. It’s another project in progress.
