For me i took it off.
Left it off and put it back on 2 days later. Dont think it suits it.

Spoiler-less will NEED to be dumped with hella flush rims and rear diffuser.
If not stick with the STI wing and be done with it.

I should have clicked C cause I didn't read the thread first and look at what WRX you actually have.
I think GC8's should have wings, I'm not so sold on the standard wings on the models after that so......dumped with a nice set of rims and no wing looks good post 00 imo.

Put it back on, GD's look gay as aids with no wing.
