At the end of it all, if you're gonna do the spoiler, you have to do the whole package- it's about the lines of the car, you know, the one that Toyota spent $10's of millions of dollars developing?! Buy the full kit or make sure it co-ordinates with what you got, or it will look out of sorts on the car and therefore siht, whatever you buy...
IMO, there is no point on spending $$$'s on say, a front spoiler that ruins the side profile of the car, same as there's no point in buying a TRD spoiler when you only have standard suspension and minimal kit elsewhere on the car.
My advice is that if you see a decent piece of kit, think about how it will look on your car- if you think it will accentuate the car's appearance, grab it and do a decent install (I hate taped boot lids!
). Whatever you do, make sure it's a complete job, or you'll never be happy, and if you have any doubts, walk.
Spoilered, despoilered, the levin looks fine- its the total package that counts.
Ahhh, feel much better now...
