What your your ultimate goals with mods? I ask to see if you ever plan or even thought about a TT in your future?
If so, I highly recommend a megashort SYE instead of a standard SYE. You will gain a better driveline angle from the start.
If I were to do it all over again.... I would go with JB or AA. I have a Rugged Ridge SYE and had problems in the beginning. All sorted out, but still wish I went with a reputable brand for peace of mind.
