system is next for me, then wheels and suspension, im waiting for my stock rubber to get worn

 

Wired: I have a smile every time I walk up to my car. The OEM wheels are hotness. Just heavy.

Someone said that a suspension is too expensive. IMO $200 for a great set of springs (Hotchkis or S-Tech) is dirt cheap. Labor to install isn't much, either. The Z handles great, anyways, so I went for performance first, as noted in my sig. But technically, my first modification was the tires - I got Pilot Sports and Dunlop M3s for the winter.

I will be getting Hotchkis springs very shortly, though. Wheels will have to be last. I don't like much of what's out there, everything just looks too generic.
