Here's some info on an LSD swap for those interested:

You send them your pumpkin, or a core charge, and they send you the modified pumpkin with the Quaife LSD in it. I assume at this point, it would also be possible to throw in the auto-trans 3.48 final drive. I'm contemplating this, but I'm wondering if the ratios would be short enough that traction would be a problem in 1st and second.
Here are the numbers:
Here's the numbers with that setup
1st: 37@7k
2nd: 62@7k
3rd: 94@7k
4th: 125@7k
5th: 149@7k
6th: 171@7k
60mph in 6th: 2450
80mph in 6th: 3250
With stock 3.08 FD those numbers are
1st: 41
2nd: 70
3rd: 106
4th: 141
5th: 167
6th: 192
60 mph: 2200
80mph: 2900
Any opinions, or anyone who's tried it in Europe?
