The spec miata continues….
So a big issue with Miatas is the rear suspension. The throughbolt in the rear carrier is exposed and becomes siezed. Also the rear axle splines sieze into the hub. After destroying the axle, chopping the bolts into pieces, leaving it under 24,000lbs pressure overnight, and finally putting a cheater bar (allegedly) on the press, the carrier was finally free. This had to be done since the frozen lower carrier to control arm bolts would have caused some crazy handling issues.
