I have lots of pics in another thread which show the car in stock height, lowered 2.0" and then finally lowered with the 1.2" H&R springs.

The vehicle will always drop more than what they claim! I actually measured before and after installation. My car dropped 1.75" with the 1.2" springs. I would measure and take pics so you know how much it
really dropped. So if you get 1.57" that's perfect; but if it really ends up being 2.0" then that's too much and you will bottom out on potholes! But it will handle like a race car!! I know 'cos I had it that low to begin with...
