Toyota & Grassroots Motorsports
Regarding references to Toyota LSD in MR-2 Spyder and 'clutch packs':
I'm pretty certain I read that the LSD offered in current/new MR-2's is a Torsen, which doesn't use clutch packs (not being a clutch-type LSD).
After reading an excellent, but brief article in the May issue of Grassroots Motorsports on LSD's, it's understandable why Lotus is taking so much time to evaluate and make a decision on what to make available for our Elise's. There are several types of LSD, including clutch, ratchet, cone, viscous, etc. and each one has variable characteristics that are modified to meet the requirements of each car and its intended use. It's obvious that there is more to selecting an LSD for the Lotus than merely finding one that fits the housing. I would think the characteristics of the Celica GT, being front wheel drive, would imply a different setup of the LSD than would be suitable for the Elise. Probably some difference, although more subtle, when comparing the MR-2 to the Elise.
