The best suspension upgrade for cornering?

I'd put the suspension/steering/tires/wheels/brakes at about 10K.

I agree. I have Bill's RMS Alterktion front, with his street linx for the rear, American racing 17X8 front with nitto 555 245/45/17, and 17X11 rear 315/35/17...car should handle like a dream..but i do have close to 10k in that setup..
