Craig,
I would be interested in your progress on using the rx7 s4 rears as I have a set at home and have been considering trying to mate them to a T series diff I have. Before anyone jumps on me, it's a JDM diff so I can't use the corona set up without some modification, and I figure if I'm going to modify, then I might as well use what I have already.
A quick question for you. Do the rear brakes use an internal drum for the handbrake, and regardless, how effective is the handbrake on them?
Regards,
Chris.
