You'll be fast and furious! haha, just playin'. :run:
I thought of doing that same thing to my car, but the car wouldn't look as clean and smooth as without decals. If you got it done professionally and with a shiny decal it'd looks really eye-catching. 2 cents.
There is a guy locally that had flames painted on a BRP RS. He had it done in a pearly 2 tone paint. It is very understated and you can't see it unless you look hard, or the sun is shining directly on it. It looks kewl.
As far as that decal, I like the way the horse 'bursts into flames', but I wouldn't use a horse myself. If it is what you want, go for it. How about a Subaru Logo that burst into flames, that would be kewlio!
I live by you, and I got to be honest with ya bro.
In my opinion, the horse decals would look kinda cheesy. Especially in a charcoal metallic against your STM, they would really stand out and be too flashy.
But, on the other hand, you drive a damn cool car, and I know you turn heads everywhere you go cuz I always do. The decals would turn even more heads. But I would agree with these other guys on getting the star cluster instead of the horse if you really want to do it!
