SAS is a Solid Axle Swap...removing the IFS (indipendent front suspension) and replacing it with a solid axle suspended by a link system or leaf springs. This is a poppular option form IFS equiped vehicles that are used for off road endeavers.

I have my VX lifted with OME912 springs (rear) and torsion bars turned in the front as do a number of others on this board. This acheives a 2.5-3 inch lift. I also did a ball joint flip. The ball joint flip allows more adjustability when getting an alighnment done. With a proper alighnment I have seen NO exsessive tire wear. They are wearing evenly.

Hope this helps and congrats on becoming one of the obsessed!
