I looked into all the coilovers on the market today and had to decide between ST V1 (same build product as KW V1 and the ST's actually made by KW) and the F2. I chose the F2's for their ability to raise and lower the strut body while still attached to the car and leave the strut piston at its full capability. With other coilovers if you lower your car, your actually lowering your spring and strut piston down into the strut body. The F2's did it the other way around so you can still keep your full dampening with the full range of the strut. The springs on the F2's are actually Eibach springs so they are pretty solid.
I don't think anyone here will lie to you. Coilovers are a significant investment at around $1K+ for a solid set. This is one area where you don't want to skimp on the product or features. Do as much research on the products you might get (KW, FK, ST) and contact the vendors to ask them questions. If you do autocross like in your pick you are definitely gonna need to look at the second version of each of those so you can fully leverage your daily driving AND you auto-x
