I think when I do springs I'll do FMS B springs. It won't give you a 1.75" drop, more like 1.25" or so, but it should ride similar to stock since the springs are progressive rate. Coil-overs are a great option also. Adjustable ride height and you can order a spring rate that will favor weight transfer.
They become stiffer when given some pressure. Like when you dive into a corner the spring rate goes from like 425 to 550 or something, I'm not sure on the exact numbers.
