I'd hazard a guess that Andy Bates would be a better person to talk to about BEC fitment for both road and track.

Whilst Burtons do know Ford they don't know as much about BEC and they are expensive
Locostbuilders all the way
You can swap crown wheel and pinion as a matched pair to another Sierra LSD diff
I have never seen any Sierra LSD apart from 3.62, 3.64 or 3.92
Quaife ATB LSD can be fitted

True, you could buy 2 Ford diffs and make a long LSD, but would you see change from £500 for a diff made up of 20-25 year old parts?
In that respect, a Freelander diff would be the viable option. BMW might be worth a look at; they made plenty of LSDs in several models that are long enough for a BEC. There might be fitment issues though according to another user on this forum who has tried it. It's worth looking at though IMO, but you might need custom driveshafts or modifying the rear suspension to take BMW rear hubs.
I once went out for a ride in a ZX9R engined car. I loved it, it made me want a BEC and I very, very nearly bought a donor bike a few days after. I put myself off when I looked at the additional cost and work that going for a BEC entailed, especially as I wanted an LSD too. I came to the conclusion that the best way to go was a BMW diff, but I would have had to go for BMW/MX5 hybrid driveshafts. Not cheap.
