Both diffs have there weaknesses , grown wheel and pinion can also be a problem on the supra diff due to the collapsible washer . But fitted with a shimmed solid washer prevents this , also the spring load on the lsd will make big difference to the torque breaking load . I'm actual going down the supra route but the diff will be rebuilt before getting used , new bearings , seals , solid washer and a kaaz super q lsd .

These diffs are over 20 years old with probable high mileage to go with that , i bet a lot of these diffs will be spinning one wheel ...lol
