I am building a Monster v8 Mazda Miata and need some rear suspension parts.
I have been told by others making the V8 swap that the 90 - 96 Tbird.Cougar rear suspension is the way to go.
Do any of you guys know where I can get to a website for some pics and info on the REAR sus and diff for one of these cars ?
You might wanna check out mn12performance.com's technical article on strengthening the IRS subframe. It's got alot of really good pictures and a few good technical drawings of the tbird/cougar/markVII IRS. I would suggest going with a Mark VIII IRS since its got aluminum lower control arms and is slightly lighter. If you get one out of a tbird or cougar make sure it came out of a V8 or SC car so that you get the 8.8" differential. They should have a tag that indicates what size diff is.
