Hello, I'm new to this sight and know absolutely nothing about the WRX other than that I like it. My G-friend just bought an 05 WRX wagon. It's very nice and fairly quick. I'll be getting her signed up on this site soon. I'm also going to spend some time looking over the site to get some ideas for mods. She has a the factory warranty and the Subaru certified warranty and we don't want to do anything to void them. That being said I'm sure there are some things that we can do that will increase power and/or handling for relatively little money. If anyone would like to give me a few tips I would appreciate it.
