While I'm not racing my Sprite, I've been using one of the Quaife LS's for
autox duty. I've never heard a clunk coming from my rear end since I
swapped the pumpkin. The improvement in grip was amazing in an autox
setting and easily improved times by 2-5 seconds on a 1 minute course. I
heard plenty of clunks before I swapped the pumpkin (along with much inside
rear wheel spinning), so the noise my have been something other than the
LS's fault. Were you using a Quaife or something else? Of course a welded
rear would work OK for a race car and be cheaper as well.
