Mark,
Don’t you think the bolts need to be
torqued? If you tighten them down against two plates, there will be some
springiness no matter how stiff the plates are.

Kelly,
Yes, spacers will be required, approximately .250" thick, unless I
decide to connect the two plates via welding, then it won't matter if they
touch or not. Originally, I thought they would nest together without the
need for spacers. I like the idea of bolting them so it can be
disassembled if necessary.

20B/RX-8 flexplate
All,
Attached is a
picture of my proposed solution to the cracking flexplates. I used my old
13B flexplate, removed the ring gear, and nested it inside the 20B/RX-8
flexplate. It could be held together by bolting or by welding around the
outer perimeter, similar to how the ring gear is attached, although welding may
cause warping. If bolted, there would be ten bolts holding the two
flexplates together. I favor the bolting method as the four bolts holding
the aluminum adapter will be a bit tricky to install and bolting would make it
a bit easier to assemble.
