My rough measurement says 1.25, it could be slightly less. To be honest the drop was my biggest fear in getting these. After driving it on all the same roads with the same speed bumps as before you won't even notice it. As has been mentioned on this forum in other posts the stock suspension is so soft just adding a coffee would drop the car. I exaggerate but you get the idea.
When I sit in the car now it moves mm's, with OE it would move an inch.
