My Superformance owner’s manual lists specifications for ride height w/ specific tire sizes. I’d have to check, but I believe the spec for the 255/60 x 15 & 275/60 x 15 tires is between 27” & 28”, measured from the ground to the lip of each wheel arch. Raise and lower the car by rotating the collars. Remember, alignment and handling characteristics change as the chassis height changes.
