If it's going to be used for racing only, why not go the solid axle
route and have it all welded together? It'd probably be cheaper
than buying any limited slip dif.
My TR4 has a locker limited slip (not sure whose). At least the
guy I bought it from called it a "Detroit Locker". I'm not sure
but I believe the Quaife's are locker type diffs as well.
The other type of non slip rear ends use clutches to do the job.
I believe "Salsibury" rear ends are the "clutch" type limited slip.
Locker rears take some getting used to. They are either "on" or
"off" The rear seems to pull a bit to the left under power when
the locker engages, and you will hear "clunks" occasionally as
it engages. The locker becomes more evident at low speeds and
tight turns where the clunking and sometimes a ratchet sound can
come from the rear.
I installed my locker for autocrossing initially, but my`4 is
primarily a street car and a summer month "daily driver". The
locker has been in the car for about 8-9 years and (knock wood)
reliable.
