^^^ I'm going with the Weir Performance MaxGrip LSD Kit which has 12 plates instead of the stock 8 plates. Here:

They've also indicated they're working on a machined pressure ring to convert to a 1.5 way LSD instead of the stock 1 way. So I'm going to get in touch with them to see about the timing of that (and hope it'll be ready by Spring), then do it all at once.
