My Bora has the 3.77 ring gear. It drives fine in traffic but drives even better at freeway speeds. We tend to drive pretty fast here in So Cal when there is no traffic. Since I never use it for work and such, usually my freeway drives are in the 80 mph range. It drives great. The Pantera on the other hand at 80 mph is not as good it revs too much for my liking. In my opinion since the engine is pretty powerful it would benefit from the 3.77 gear. Problem is the cost outweighs the benefits.
