[Fot] Advice on Differential - Stock, Lock or LSD

[Barr, Scott]

I have been using a Quaife in my Spitfire for the last 10 years.  I have no
complaints other than the fact that, once you lift the right rear tire, you've
got an open diff.  Otherwise, so far so good.

I'll be experimenting with a Detroit Locker this year, which I hear is going
to require a slight modification of driving style.

Well my GT6 has O/D and so it was supposed to have the 3.89 ratio diff.  But I
have found that was swapped out at some point to a 3.27.  I want to go back to
a 3.89 unit.  Any good sources for one?  And for road racing, should I go
stock, weld it, or go with a LSD.  I hear of a lot of failures with the Quaife
units - so I hate to throw a grand at that product.  Any advice is
appreciated!

Thanks,

Chuck Watson
