With and LSD, this wouldn't happen since the locking would distribute the torque to the other wheel as well minimizing wheel slipping and thus putting more stress on the r&p
The upside is you have a good performing vehicle. I will take the potential side-effects to have good diffs in the car.
As some one who's chewed up spiders in stock rears. I'll take my chances with the putting more load through the bigger R&P, then suffer the horrible performance of stock wrx diffs.
my .02 and good price on the plated diff. I run the m-factory helical in the front and I would say it's been stellar, quality wise, thus far.
