Speed Shop in Northern NJ

Hello all,

Im looking for a speed shop in Northern NJ also your recommendations on a full body kit, spoiler & wheels/tires.

I have the audio system done already on my 2004 350z Enthusiast Roadster.
1. Pioneer Avic Z3 touch screen DVD/Nav
2. Custom built box with JL Audio 10W6 behind the drivers seat.
3. All stock speakers replaced with Alpine Type R


The mechanical upgrades done are
1. Full dual exhaust
2. Intake.
3. Alarm with remote start (yes on a 6 speed)

I would like to get some ideas what to do next mechanically and cosmetically.

Thanks for helping out.
