Welcome, Lots of great info here on this site. Also a lot of people that have owned these cars for a long time and been modding them for 10 years. Search is a great tool, use it. If you can't find it on search we are here for you. We have had a wonderful forum here. Some of the new guys don't respect what we have. Hope you fit in with the guys who have been here awhile. Most of all enjoy the car. Bracketracer has a GXP registry. Recommend checking in with him.
