need some help on 370z ideas

ShinyaPGH

I'd like the idea of adjustable coilovers, that I can adjust between the street and the track mode. To go faster on the track, suspension & brakes are the key anyway on seconds/$ scale. An exhaust and a body kit will be the minimum bling for the street, while putting most of the money into brakes and suspension is the way I'd like to go. But it has to be streetable enough in the summer months of Pittsburgh, PA. Engine mods are secondary.
