So I have the transaxle and torque tube at the house now, and I can confirm they are very light for a trans/diff combo. As I said before, using some other rear diff and fabbing a reverse setup would likely get me close to 100lbs anyways so I'm happy with this setup for now.
Ive been looking around at upright options now. Few canditates are cobalt/g6/pursuit aluminum units that would require some type of fabrication to use upper ball joints-Having trouble finding what others have tried
.... PS-These uprights are extremely light!
Another option for even less money is the c5 corvette units. I was surprised to find them under $50 on ebay, and front to back they are the same units. Someone else mentioned though that they would require a much larger rotor/rim package. Can anyone confirm this?
I don't want to start the frame build without having these parts figured out, as it may change my suspension layouts.
