Purpose of the car, in order:
Spirited street driving, occasional AX, occasional track days. Here's what i think i know (IMG:style_emoticons/default/biggrin.gif) LSD - Always locks wheels together under acceleration and deceleration. - Introduces understeer in slow corners. - Generally considered the better choice for the big track. TB - Only locks wheels under acceleration. - Acts like a open diff if a driving wheel is off the ground. So, the question is, what should i get for my 915??? The car will never be a dedicated track car, it's mostly driven on the street. The TB seems to be easier to drive on the street. However, the slow corner understeer of a LSD could probably be tuned down with suspension settings. The TB loses it's magick if one wheel is off the ground. In an AX setting, the suspension would need to be pretty stiff to keep both wheels on the ground at all times, would a LSD be the better choice here? Anyone compared the two back to back in a 914?

My experience with the Quaife TB diff has been that it is great on the AX course. I hardly know it's there. It puts down the power and I love it, for AX. On the street it is fine until you start doing some tight radius stuff like tight turns into a parking space. Then it feels like a locked diff!! The tires grab and slip. There may be something wrong with mine, I'm not sure. That stuff about it acting like an open diff when you lift a wheel, not true. Last fall I broke a CV joint and so you would think it would not transmit power because that is about the same as lifting a wheel. Well, I was able to drive it. It put down power to one wheel. Pretty dangerous as the car would jerk one way when I hit the throttle and jerk back when I lifted. But I was still able to drive it and get it home. I find the low speed stuff to be very irritating and think it may have contributed to the broken CV. As my car is pretty much AX only with very little street driving I live with it. I wouldn't like it for a daily driver running errands and stuff. You may remember I was at the Doc's tranny clinic at McMarks talking about it and checking out Rob's tranny trying to see if mine felt different from his. I would recommend that you drive Rob's car sometime a see for yourself.
