Or SAVE a bunch of money and stick in a spool.
Pros: No quirks, no noise, always 100% traction, never wears out, nearly bulletproof.
Cons: Increaded turning radius, tire scrub, increased tire wear, not great in icy conditions.
I had an auto locker in the rear of my DD for a couple years. WHn it broke, I was low on funds and dropped in a spool instead. I liked it MUCH better on and off the road. That is just my opinion though.
