Welcome! go with a ITR front lip & ITR spoiler.
oh yeah and add some sidemarkers! :thumbs up but you can't be afraid to cut into your fenders.
btw. I'm located in San Diego.
Looks good. When I put on my ITR spoiler the GsR low deck spoiler didn't leave any additional holes to patch up. The ITR bolted into the same holes as the low deck spoiler. There was some weather stripping around the outter edges of the GsR spoiler but I was able to gently scrape that off.
Sidemarkers add a touch of class in my opinion. Really clean and that paint is nice and shiny,
