WHat he said.
FAshion has a price. What you are experience is too much rim and your car is too low. The camber specs are JACKED. If this is the look you want, get ready to live with the crappy performance you have inherited.
The question is, now much crap are you prepared to live with over fashion.
The fact that you think it needs more of a drop is insane. Lower is not better. If all you care about is looks then fine. Its your car do what you want...but if the car acting and driving like a new car means anything to you, then you need to find some happy place between modding your car like an educated person does, and modifying it like the hellaflush yahoos do around here. Do not get sucked into the moar low nonsense.
I would wager that getting your camber specs closer to normal will fix all your problems. If you cannot run more stock like camber specs then I guess you have a choice to make. Live with these issues, or sell your rims/tires and get something a little closer to OEM.
