I happen to be a fan of the LEG Sport kit (with the exception of the spoiler). If you want to be unique, you could go for the TOM'S kit (not a huge fan of the front, but the rear looks awesome).
I think the Tommy Kaira front bumper makes the car look like an XV20 (late 90's) Camry with an XTREME TO THE MAX body kit, so I'm not the biggest fan of that either.
Revolution makes a pretty nice bumper that maintains most of the stock look:
You can get it on japanparts.com but it's pretty expensive.
I think your best bet is to buy a used front bumper and then vinyl wrap the car whatever color you want.
