I had Steve (the owner) at Aerosim install Prodrive's new springs for the '04 STI, a full set of Brembo cross-drilled rotors, and Perrin's rear end links today. I couldn't be happier! Steve is a very friendly and personable guy, unlike the guys at Easystreet! He installed everything without any problems, and had me back out on the streets in no time. Aerosim is about an hours drive for me (with light traffic), but the drive was definitely worth it. I will return for any further mods that I cannot handle myself. Thanks again Steve!
