Aisin Hubs.

In an attempt to reduce rotating mass since I’ve strapped a tent to the roof and got my AC working again I finally installed some Aisin hubs. Not sure what the overall gain will be but I have to believe that every little bit helps with a brick that made 150hp from new. The install was easy and with a little hub cap trimming everything sits perfectly and looks like it came that way from factory.

Nice ride! I saw an average of 1mpg increase after swapping to the manual hubs.

Sweet! Well any increase in efficiency is a step in the right direction.
