There are a few advantages of a coil over system compared to most stock systems. Typically, they are compact and lightweight. They also offer a broad ranges of spring rates from very light to super heavy and are separated by only 50# increments. They allow fast spring changes and easily adjustable ride heights.
So, if you need a lightweight systems with access to multiple rates that allow quick changes, then a coil over system is for you.
If you prefer a set it and forget it approach for something that allows you to have fun driving your vehicle, then you most likely only need to step up the rates slightly, improve your alignment specs, and get better tires.
Hotchkis and Firm feel can offer you stock based systems that can be incrementally upgraded over time, or all purchased at once for a complete make over. A call to discuss either approach and specific items recommended would be time well spent.
The shotgun approach is simply 1" t-bars, 1.125" front sway bar, XHD or equivilent leaf springs, better shock control, 2005 Mustang GT alignment specs, and 200 treadwear tires.
That sounds reasonable enough. Just deciding which brand of parts seems the battle but I do love the Qa1 lower tubular control arms and I can get them at Mancinis for a descent price
