To sticker, or not to sticker, that is the question...

OK - a little promo for the Eurocharged team  - Great company to work with so far, and very good stuff!  They sent these to me in the mail...  they're grey to somewhat match the silver.  I know, I know - if I got yellow or red stickers it would add 50HP- but I'm ok for now ;)

It will look a little like this... but my windows have a little tint so would darken the background

So what do you think?  Should I put them in the rear quarter windows ?
