Has anyone had experience with doing an RX8 spindle/brake upgrade, or possibly the late model 5 lug front system?

 

Yes indeed check out this blog. Best ever! MiataV8 Conversion

 

Thank you, thank you, thank you, Jim!! Amazingly easy conversion. I was barking up the wrong tree with the RX8. I guess the guy building the tubular subframe for RX8 suspension must have given up.

 

 

I'm glad you linked Mike's site. I had never seen his site, just some photos of the rear control arms. I love what he did, It's what gave me the idea. Using the ford rear spindles makes it a lot easier to do high hp axles, which seems to be the weakest part of V8 swaps I see. I liked your use of the Audi boot on the axles, as well. Nice touch. Just have to get a custom center shaft built for my car and I'm golden.
