So I'm taking this a step further and I got a whole new carrier out of an IS300, which I am then going to install my final gear into.
The reason I bring it up is that Spence over at Weir Performance (
http://weirperformance.com/) sells gear kits for the mark 3 Supra, which he knows to be compatible with the IS300 carrier (he's sold them to a bunch of IS owners looking to do final gear swaps). Seeing as the IS300 carrier is a direct swap into our cars, I would think these final gear kits would be swappable into our carriers as well.
It's like that one mathematical property... if A = B and B = C, then A = C.
Take this with a grain of salt though. I've not tried taking one of these final gear kits for a Supra and installing it in our carrier; my plan is to install it into an IS300 carrier, which is known to work. Maybe @
Jeff Lange could shed some more light on this issue?
