Hi guys! im new to this forum and a first time Subaru owner. i recently picked up a 02 wrx! Let me start by saying i love the car so far! Im well aware that im never supposed to launch the car and to kind of take it easy. The engine is completely stock and has had the radiator and fuel lines replaced. Along with that stuff, the front sub frame and front control arms were replaced. While all that stuff is good, the rear undercarriage is pretty rusty. the attached video shows the amount of rust. Im looking for some advice on what i should replace and what i should let go, (i.e. rear control arms, rear sub frame, and other stuff regarding whats shown in the video.) any advice is appreciated, i am a complete noob when it comes to these cars so please be nice anyways here is the link to the video. Thanks again in advance!
i forgot to add, when i take off (even gently) i will hear creaks coming from the back. im assuming its a result of all the rust, what specifically could it be? the car has new suspension all around
