Boxster Storage on an inclined surface
 

Is prolonged storage on an incline plane side to side and fore and aft a problem? I am thinking about oil getting where it shouldn't; unibody deformation; asymmetric suspension loading (spring set) etc

I'd guess it depends how severe the slope is.
My garage floor has a 1/4" per foot slope, and I've noticed no ill effects with my Boxster and the 5.0 Mustang I had previously.

Depends on the duration and slope. If its minor, nothing to worry about.

If both were severe, the downhill side will carry most of the load and the tires or steering rack might be affected. Tires might flatspot from the long duration and extra loading. Steering rack could be under stress if you turn the front wheels right or left when parking facing up/down hill. Shouldn't be a problem for the chassis or oil.

No 3.

Hard to see the grade ....will have to measure it

Define "prolonged".

Up to 7 months without moving.

I like the parking spot the silver Ford is in.
