Just became a member. I've been reading posts for the last hour and it seems like a really great group of members. Last June I purchased a new 06 Roadster. 6-speed in black. I love this car. I would like to add some modifications to increase horsepower and torque. What would you recomend I do? I am not looking to go crazy. Just one or two modifications to start. What are the one or two things that will give me "the biggest bang for my buck". Thanks!
