It's not quite that simple. If I want to go with the lsd I'll still have to track down a base 5-speed tranny since I have the sh. And that equates to about $1200 or so more. Or should I just stick with the sh tranny (no atts) and just build that motor? I just figured if I'm aiming for 400whp a lsd would help lots with traction. What do y'all think?
