2" is going to be too much for these cars to handle on just springs alone. You would be able to do it with coilovers, maybe, but in all honesty, 2" will be too damn low to drive the car anywhere...
I know there's a member on here who has true coilovers all around. If I remember correctly, he's on 20's and is 2.5" lowered atleast. I'll try and find the thread on it.
*Edit*- search for a member named "turka". He has coilovers on all four corners. Lowered over 2" on Brembo wheels. Looks sick.
Like jedi was saying there is h&r's that lower 1.7" F and 2.4" rear. Goto american muscle and look at some pics of the cars they are on. They look great. And take some of the rake out of the stance.
