This might be a little off topic, but I am looking for advice for a traction aid for a rear-drive car. I figure you 2wd guys would know best.
Specifically, I am looking to be able to get traction when one wheel is on ice/snow and the other on pavement and other variable traction conditions. The application is a full sized Ford car with and 8.8" rear. I have used stock trac-loks and find them to not be much better than an open diff. in difficult situations. I have also heard Auburns don't do well in variable traction conditions either. I am willing to put up with some chatter and noise but I think a full Detroit locker may be a bit much for me. What other options would work well? How positive are the Detroit 'soft lockers'?
I've got an Auburn in my Bronco and I love it. According to Jeff at M.I.T. here in El Cajon, CA, they don't work properly unless you enough (read more) limited slip lube in the oil. As I said, mine works great. It's damn near a locker without the downside.
