It seems a lot of the Subie stores are dropping links to our Legacy.
For the most part a lot of Impreza parts fit our cars, so on any particular item suspension, coilovers etc check out the search.
I do know one company that has blessed us with options is Whiteline. Check out www.pdm-racing.com
Or you can search their extensive product line at their home site. http://www.whiteline.com.au/
Oh, and Mustangracer, even though it doesn't add much power. A nice catback and intake still adds considerably more fun to the ride. The Butt dyno appreciated it. Real power is a bit harder to get. Handling and brakes are much more rewarding for the dollar.
