Stage7

Hello,
I currently own a single turbo Supra...
I've always dreamed of a Supra powered FD..
Now SP Engineering has inspired me even more.

My question is, how strong are the rear end compenents? Dif/axles/u-joints/etc?
What are the et/mph/rwhp limits of those components and are there any upgraded parts available for them?
I used the search function, but I didn't find much to answer my questions..


Thanks in advance

BTW, I'm looking for a 3rd Gen shell, so I'd appreciate any leads...
