The reason that the rear ride height measures like that is because the rear fender lip on the classic is designed lower then the front. it has been mentioned in a few threads out there.

Benito Malito did the zip tie test to determine whether the car hit the bumpstops and the rear did not make it to the bumpstop.

The front did hit the bumpstops, but please keep in mind that people still reported hitting the bumpstops under hard cornering even with the universally praised Hypercos. I am having them make the front a 1/4 inch higher then it was before to correct this.
This spring is better performing than every other spring out there with the exception of the Hypercos, which were the only other spring out there with good R&D put into them.
If you are looking to put anything other then stock springs on your car, for the price I do not think you will find a better value then the Road Magnets. These springs were researched, tested, and have recieved great reviews.
