Just got a gsr
the first thing I would do is ensure its running its best now. Go over the belts, the plugs, all the fluids, the brake pads, etc... and make sure you've got a very stable platform to start from. After that the most common and reasonably least expensive upgrades are aftermarket intakes, catback exhausts, headers, and freeflow catalytic converters. These combined tend to lend a little more power to the car and are pretty much the first step for most people who go the performance route. Have fun and welcome to the board.:thumbup:
