I was just referring to base prices, not extra parts and install costs. I don't have an LSD just trying to do some basic research from what I've seen other members run to help you out. You've got dp3ngu1n's total for the Giken plus surfdogs for the quaife. It looks like either way it'll be over at least 1500 with the install. Again gotta figure out what you want from a DD or weekend warrior car. Those guys will be able to tell you their experiences I can't. But I can say it won't be a cheap upgrade so just keep it in mind, I looked into it a little while ago and just couldn't justify the cost right now. But that's my choice, I've just been putting funds towards other parts of my car
Here's the "base" prices I was referring to
Quaife base price without anything else is 1100, Giken is 1600
Basing those off of here:
Quaife Differential
