Got myself some Scion Life decals (8x3, silver) for my FM tC.

Any suggestions as to where I should put either?

I'm thinking at least one on the roof pop-up air dam, or low on the rear window.
Maybe even the rear triangles.

Trying to avoid paint if possible.

Well I dont want to seem like a "ricer" but I am doing
roll calls down my doors on both sides and along my side
skirts on my body kit

but in your case i would put that sticker on maybe the
front fenders or on the rear side windows
