I own a completely stock 97' M-3. I feel silly complaing but, too much body roll. Can someone suggest the first and most cost effective suspension modifications to be made. I have the stock alloys and like them a lot. Keeping the same wheel size, I thought I would make the following modifications: 1)BMP lowering springs(street performance not sport), Bilstein sport shocks, BMP front 27mm sway bar, BMP rear 22mm swaybar, BMP front and rear shock tower supports. BMP crossbrace. The one really large question I have: Can you lower the car without puting in camber plates, front?, rear? I know they can increase cornering performance and reduce tire wear. What's critical? Any help is appreciated thanks.
