Here’s a quick post on adjusting your Miata’s Camber
Most stock setups are somewhat limited in how much negative camber you can achieve. You can install extended lower ball joints to get more negative camber.
Here is the recommended alignment from 949 racing:
Dual Duty Alignment is intended for cars that will occasionally reach the limits of traction and slide the tires but don’t want to give up too much tire wear for daily driving. To reach target camber and ride height will usually require modifying front suspension with extended ball joint or offset bushings.
