Question for cpp front spring drop users

[walls]

Yesterday I put a set of rear 4" lowering springs on my suburban. Right now it looks ridiculous because it still has the stock springs up front.
I have 4 1/4" between the bump stomp area metal and 2" in between the rubber bump stomp.
I have a set of 2" lowering springs/shocks back-ordered from cpp but I'm wondering if they'll be low enough to level out the car. I imagine I could call up and change them to 3" no problem.
Just looking for opinions on the springs from anybody that has used them. If you could tell me how much room is left between your bump stops after using the springs, I may be able to get a good idea as to how the truck will sit after installing the springs. Thanks-Bob
