Fairly new to the Subaru scene, I bought a 2003 SE L Wagon and had some questions. What's BE and BH as far as designators/types? What other codes pertain to our wagon that will help me look for parts and engine/body products?

Our wagon is basically the family wagon but I'm the type that can't leave my car totally stock. Just a few costmetic changes would be lowering springs, rims and tires, rear wing and maybe a light smoke tint all the way around. (changes=nothing too drastic, more into the subtle, sleek, clean look)

What's out there as far as mild performance without jeopardizing reliablity (we've got a 5 year old and our Boxer-"IRIE")

Thanks for helping us out, we're in the Pleasant Hill area, be safe out there! Aloha.
