Now you're my kind of Tercel guy!
Huge welcome to ya!
I'm a bit stretched for time at the moment, so I have to make this short. But I'm a big rally, rally-x, navex, drivex, autox, etc, fan myself. Basically, I enter my car in anything that they will let me do without a rollcage. We'll have to talk more later.
Oh yeah, if you want an LSD, it'll have to be special ordered from Japan. Quaife America used to make them for us, but I think that's been discontinued. You're only other two options are TRD, and Cusco, but like I said, they'll both have to be special ordered from Japan.
