Being VERY tail heavy, no. It is not entirely good. Unless you cant seem to pull out the rear end with ease.
In addition, it is not due to the LSD to have a "very heavy tail" feeling. STOCK LSD isnt that heavy to give that feeling. Its your suspension setup making it feel that way.
Torsen gears will start to wear out if you continue to thrash it. It'll take a hardcore beating ill tell you that. Its not nowhere as cheap as the Nissan Viscous type LSD's. You'll have to rebuild the Torsen LSD or get a new LSD once your original Torsen LSD starts to feel the effectiveness starting to degrade.
