Hi i am from denver i own two wagos both are 1991rts red and brown
...or the 2nd Gen CRV steelies
Another wheel option (if they'll fit) are the FD RX7 wheels. 16x8 and less than 15lbs.
Honda should have the proper fluid for the rear diff. It is different than the Wagons as the "center diff" is in the front of the rear housing
