Here is a set of great condition Legacy Spec B axles with the WRX outer CV already swapped on. Ready to do for your 6 speed swap with R-180, but you will be able to keep your WRX hubs, brakes, and wheels.

I am asking $550 plus shipping for the set. They cost me $500 plus shipping, plus a set of WRX axles, so I think it is a good deal. I am selling them because I scored a set of 5x114 hubs, and it will be kickass to have both of my cars able to share wheels

These were properly swapped. Outer CV have about 50k miles on them before my 6 speed swap. The Spec B axles had about 25k before they were removed.

The bottom picture confirms that they fit in an R180. The R180 is NOT included
