Sorry about the double post - something's amiss here!

I've heard both good and bad about camber kits. I'm aware that if you lower the car you'll probably need to adjust for negative camber. Are there any camber kits worth buying?

Once you put on a kit like the "Wicked" ones on eBay, do you lose any clearance in the wheel well? I'm lowered and on 17's so I can't afford to lose any more space.
