i personally have used and recommend APR chip, K&N drop in air filter, a Techtonics Tuning downpipe and exhaust.
suspension wise go H&R or Koni...
I would stray away from the APR chip as they have a problem burning up frying ECU's. There are 20-30 people suing APR currently. Since it a readily available in the ATL area, REVO is what I'm going with.
