looking to buy a forester xt..got a few questions

right now i have 3000gt and i love it...but i really need something that i can drag my dog around now, plus soon i might be starting a family...so i wanted to get an suv, preferably an xt. i no most sti parts r interchangeable. but what im most worried about is the suspension.

i wanna drop it considerably from stock height...ive seen on car domain that people have used the OEM wrx sti coilovers and it drops alot..is this true and r they adjustable??

also i like the look of the intercooler on top where the hood scoop is...how do i get that??

what r good part sites to get to brown for parts??

wheels...same bolt pattern as stis?

sry if i sound likea noob im really not ijust wanna learn more about these vehicles
