Something interesting just popped into my mind. OP do you want to swap to 5x114 during this ordeal?
Anyway, for those who do not know, on the GH/GE/GR, all 4 corners are hub unit bearings like the front was on the 05+ STI where the bearing and hub and a 'knuckle snout' is sold to you as one item and it just bolts onto the knuckle....no pressing bearings etc. What I'm wondering is if the GE/GH knuckles are identical to the GR knuckles such that all you'd have to do is buy 2 GR front hub unit bearings and 2 GR rear hub unit bearings and they'll just bolt onto your stock knuckles. Then you'd need to do the brakes of course (might need a bracket), but this will eliminate the need for new knuckles and popping 6 ball joints apart.
Just a thought.
