Which means your going to have to replace them. Honeslty waste of money and time. Of course after you lower your car you going to need an alignment. I would go with KW I'm extremely happy with my set, it's up to you how much you want to spend but suspension is something you don't want to go cheap on. I have the same wheel spec as you and I'm slammed and I don't rub. Oohhhh yeah my car handles like no other now, no more boat like feeling at highway speeds.
Thanks for your input, I appreciate it. Yeah..a few members have recommend KW V1 for me, seems to be a popular choice. I'm assuming the quality is good, like you said I wouldn't want to go cheap. I'll look into it. What's a good height to lower it to in terms of inches?
