Alright it sounds like you need a bit of help.
If you answer some of our questions .
1) How much money do you have to play with? What is your budget?
2) How low do you want to go?
Performance sway bars are usually thicker in diameter and stiff. That will reduce body roll. Tire rack has the best price on Hotchkis front and rear sway bars which are the thickest. I am about to run those because they come with new bushings to accommodate the larger bars where as other kits use the stock ones.
I assume you are looking for better handling, how much comfort do you want to compromise?
1.4 inches front .75 inches rear being a mild drop using lowering springs that are not adjustable however less $$$. Or something more extreme and adjustable like coilovers that will lower you car anyway from 1 inch or more?
