Hey,

if it were me and i liked the rims that are on the car currently, id just get new tires for the two worn ones. Cause if your gonna end up driving on those rims, you really do want good/legal tread.

otherwise, there is a few sets of wrx 17's FS on gumtree and the like. seem quite common.

with the pod, just some metal holding it in place, does not have to be overly pretty, but just had to hold it so when the pits inspector tries to move it, it does not move around easily.

the other thing to watch for is the intake noise, ive had some pits inspectors be fussy about the amount of noise coming from the intake...altho at the time it was a dose pipe and quite loud and awesome, they frowned upon it....so just make sure there no overly audible noises coming from the pod.

with the bov pipe, perhaps try Supercheap, you can rummage through their heater hoses and find something thats close to the shape you need. thats what i usually do....otherwise yeah, maybe someone here as a genuine item FS?

anyway, free bump and good luck.
