I'm really looking into buying either a G or Z and have been trying to see what my options are for mods, the cars i looked at were all automatics. Now i'm looking for some feed back how reliable these cars are with mods and what is my absolute best way to get into the low 12's or high 11's for a car which will be driven 2 or 3 days a week. Please let me know, thanks.Also where would be the best place for the install in the NYC/NJ area......
