Okay I have gone through 4.....thats right 4 tires on my front right side. I have 99 si rims on my rex and they ride like a dream. for the longest time i couldnt figure out why that tire went down so quick. then it hit me the other day.....when i turn one of me tires slips....so easy way to fix that is get a lsd right? right. well anyways. I was wondering if I should just go but another tranny with factory lsd in it. Or should i get a aftermarket and have a shop put it in?
