I used to know what these were called, but have forgotten. Pretty cool stuff. Just take off your wheel, and bolt these on in place. The drive wheel turns the treads.
But, put a set of these on the back, and set up skis for the front/steering. It would work, and be pretty simple (assuming that your car had enough HP to even turn the snow treads). Will raise your cars ride height considerably.
MATTRACKSYou put them on all four hubs, even with 2WD/RWD. They work very well. Mattracks sells them by the set, not by the pair. If an ATV can turn them, I kinda think a 914 can too. Very well made. There is another manufacturer who makes a slightly cheaper version, but I don't have a link.
