I track mine, and she's my daily driver as well. Here's my setup (suspension/tire/wheel wise):
Eibach Sportline springsStock sport shocks/strutsNRG front strut tower braceCircuit Sports front lower cross tie braceEngine torque damperHotchkis sway barsOE 350Z Track model wheels (18x8.5 +33, 18.62 lbs, all around)Nitto NT-05 245/40/18 all aroundHawk HPS padsStainless linesATE Super Blue brake fluid
She handles pretty well. But, I think I pushed her a little hard this past weekend. The front brakes were smoking after the first session. Hahaha. No worries, though. I have the solution for that going on my car this weekend.
Any questions? Ask.
