I am wandering if mazda miata suspension will bolt in place under an mg miget? If not are there any other small car suspensions that will? OR will I need to fabricate something? I would like to use ball joints instead of king pins and the regular coil over shock suspension. All help is greatly appreciated. thanks.
No, the mounting points of an MG Midget / A-H Sprite front suspension are unique. You won't find any other small car with a front suspension that bolts onto those...
Before you start fabricating, you might enjoy studying the eight Spridgets featured on BritishRacecar.com. I'd start with this article about one of the fastest Spridgets in SCCA history: <a href="http://www.britishracecar.com/ChuckPitt-Spridget.htm">
Chuck Pitt's 1968 Spridget (Sprite/Midget) Racecar</a>. Then, you might like to contrast its front suspension with <a href="http://www.britishracecar.com/RickHaynes-MG-Midget.htm">
Rick Haynes' 1965 MG Midget Vintage Racecar</a> In the photos (and captions), you'll see that Chuck's car retains lever shocks whereas Rick's features coilovers... but both retain kingpins.
This is an MGB, but does show what a major undertaking swapping in a Miata suspension is. Not to mention, about 6" wider.
