The fact is Delorean did have 3 different hight, You can find on the fiber body a orange sticker with a letter B C or no sticker. It is most hidden behind the impact absorber.
This was in the factory a indication what spring they neat for the body.
Stock springs have yellow marking, red markings, and springs with out marking.
A small help it the remove the plug on top of your brake reservoir, if the cap hit the rubber you have a low body if the cap is a 1.5 inch deep you have the hi body.
