Question about storage/suspension
 

Read the info on here about how you guys prep your cars for storage. Put mine up a week after Thanksgiving. Followed all the advise, Filled tires to 59PSI. Got a call from the mother-in-law today. It's in her garage. Right rear tire is flat. Can't let it sit like that for long. Gonna head up on Sunday to remove the wheel and see what's up. Here's the question... stored many a Miata on jack stands over the winter with no issues. The manual on our cars says not to because of corrosion on the shock pistons. Anyone try storing a Boxster on blocks? Any issues? Up on blocks I can fix my bad tire and detail the wheels while I wait for the snow to melt...

While it might cause surface corrosion to the shocks, it also reduces the pressures on the suspension bushings. This can cause problem when the car is lowered again and asked to support weight that it hasn't for months. Not sure what year the box is, but you could put the spare on in place of the flat while you have the flat repaired.

In the end, its your car, and your decision. I like to think the manufacturer knows what is good/safe for their product.
