I'd drop it, maybe coilovers, but that may be too much, but the added stiffness and control is a plus. I'd definitely do bigger mags on low profiles, not silver, maybe gloss black, more aggressive bumper, angel eyes and xenon retrofit... Get a GTR Carbon Bonnet, and aggressive exhaust.
Performance wise, you could go crazy... anything is possible, its all down to how much you want to spend. Could go Supercharger route, turbo route or even a bigger engine implant...
