After talking with a bunch of my car-geeky friends, I decided that I really like the stock suspension for what it is - a good compromise of performance and comfort - and this is primarily a daily. I only want to take it on the track for fun, maybe once a year, and compromising the streetability of it, even with only 1/2" lowering, isn't something I want to do, so I ended up just getting B6's. I haven't put them on yet, but I can't wait for the boatey feeling to go away
Maybe in the future I'll do the M030 springs and sways, we'll see. Thanks everyone for your thoughts!
