rear sounds easy enough. Front doesn't sound bad either, but I'm a little confused. On my WRX I pulled out the whole spring+strut+tophat assembly and then took that apart to remove the springs. Is that not the case here? I guess I should go take a look at the new struts I've got in the garage. Should give me an idea of what i'm looking at. From your description, it sounds like I need to compress the spring while its still on the car. yes/no?
oh, I do have spring compressors. safety first.
oh.2, I'll also take a look for the vents. not really sure what you're talking about, but I'll have a look. its USDM spec so there may be some differences. Are these vents visible without the car being jacked up?
