Asked if I brought in a new LSD and he quoted me 4 hours (~$100). thinking about $1700-2000k for the LSD diff...

So $2100-2400 for the LSD or $1000 for used, stock???

should I bite the bullet? Is the LSD that much of an improvement? what would you guys do?

ONLY IF you have increased HP significantly and are experiencing quickly wearing RR tires and/or power cornering less than you like (one squeeling tire).
