We measured an 1/8 inch drop at the front of our Cougar (67, 289, 3 Speed, AC car) but no where near 1" as advertised.
However a much improved ride thanks to these and the new scott drake spring perches over the the 55 year old setup.
Would still recommend.
WCCC Response:
The 1" drop is not from where your car sits with worn out springs, but from where it would sit with new factory height springs.
