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?
