Good choice on the car, my lil bro has an SI and they are nice.
the kit is too much for my liking, especially the huge wing and a thousand vents in the fenders.
but you know it's ur car, I'm not here to tell you what to do.
If you want to be different then the majority of CC with their lip kits, I know I'm one of them, and you decided to go with a body kit anyways, get a BC or C-West kit, those look good.
Other than that, I think a mugen-style or si-style lip kit on front and rear on a stock body looks good.
