DDM Tuning.
Don't go with HIDs in your high beams unless you use them for prolonged periods of time (long highway drives at night etc.) as firing and shutting them off is really bad for the ballasts and wear them out longer. FYI MY 2007 GP GT SE HAD REVERSE POLARITY.
I went with 2 55W kits from DDM Tuning (the 55W kits that are 5000k show almost like a 4000k because of the higher wattage)
Here are some pictures (I installed them last night).
