Here is a couple of installation videos from S3, but I have to say after doing lots of these I do prefer to fit from the outside of the rim, and work my way in towards the spokes (the exact opposite of what's on the video).

INSTALLATION NOTES:

* A real key to success with any rim sticker is spotlessly clean rims. Spend the time to clean them thoroughly before you start with prepsol, brake cleaner, carb cleaner, or acetone. 

* I like to put the bike on a bike stand so the wheel is off the ground and easily rotated. I find a box, crate or stool to sit on, and get myself at a good working height with my eye line level with the top of the rim.

* Only tool you will need is a hair dry or heat gun (on low - don't go thermo nuclear with these).

* I start by sticking a sticker down following a 1-2mm gap on the outside of the rim, and just lightly touch it down on that outward facing surface of the rim. Then when you have the complete sticker (which is 1/3rd of the rims circumfrence) down on that edge, only then apply a light warming of the sticker with the heat guns (to soften the sticker and make it more pliable) and work the rest of it over the curved inner section and up towards the spokes. 

* When you are happy you have it down well, and any the air bubbles have been massaged out, only then warm the whole sticker and firmly press it down to the rim, locking in the adhesive qualities and making it stick fast.

* Repeat with the next sticker overlapping the stickers approx 10mm on the previously applied one. NOTE: I try and overlap the stickers so as the wheel rotates the "edge" of the sticker is faciing up as the wheel rotates so there is less chance of it "hooking up" on and debris. The means you have to work clockwise on RHS surfaces, and ant-clockwise when applying the LHS.

The real trick is super clean rims. Get some Wax and Grease remover, or similar, onto to every bit of the surface, and make sure they are super clean.

I leave a good 1mm, or so, gap around the edge to leave room for tyre irons etc. Then use a heat gun or Hair dryer to soften the stickers (makes them more pliable) as you put them on.

Overlap the stickers in the direction the tyre rotates, so if you clip something with your rims it wont peel the join away.
