Question on lowering springs 2013 gt 500

[Hogan-20]

Hello, 

 doing some suspension work to my 2013 gt 500 coupe. Going with Koni yellow front and rear shocks, pan head bar, rear lower arm relocation kit and Sportsline lowering springs.  My lowering springs are rated for 1” drop in the front and 1.3” drop in the back.  The shop installing them for me told me when they settle it will be more like a 2” drop in the front and a 2.5” drop in the rear... makes me a little nervous thinking I’ll only have like 3.5” of clearance. So is that accurate? When they settle, can I expect another full inch drop?  I don’t have a lot of speed bumps in my area but I do come across potholes and a few construction zones. I never had lowering springs before so I have no idea what to expect.

...no that's wrong. The drop is the drop. If the rate is 1" and 1.3", thats what they will drop. BEFORE it settles you might only be at 3/4" of an inch or so. Shop is dead wrong.
