Leaning Miata
 

Will be more specific, 99 Miata with 115,000 kl no winters (70,000 mi.) car on a flat level surface using a set square measured from the steel wheel arch to the top of the rim the front left is 3/4" lower than the right and the rear left is 1" lower than the right. 75% of the mileage has been with a passenger so you can't blame the fat owner. Can one side springs go soft only? It may be my imagination, but in hard right cornering the rear seems soft , like a tire with low pressure. Tire pressure is 29psi flat. Thanks for you time

The top of the spring rests on a rubber cushion that may be missing or damaged. The perch at the bottom of the spring is angled and designed to accept the spring at a particular orientation. If one side is not lined up it could be higher. It is possible for either to have happened if the shocks were replaced at some point and they were assembled incorrectly.

Thanks, I will check out the cushion. have a great week.
