I picked this kit up awhile ago because i heard some good things about it, and I finally got around to doing the job today, although these are on my GTS4 skyline not on a DSM, still a great product for anyone running bigger brakes on there DSM that they want to show off.
It comes with a caliper cleaning solution, a silver rust coating almost like a primer, and then comes with whatever colour you choose. I chose gloss black. I recommend this method of painting your brake calipers over any rattle can method, I did a red rattle can job on my old Talon and It was no where near as nice as this.
You can buy this kit for about 40$ at lordco (they usually have to order it in, atleast in victoria they did) It is kind of time consuming so dont do it on a day where u need your car. you need to allow the paint to dry/cure for 24 hours they recommend so i just finished and put the wheels back on and the car will sit over night and cure. anyway this kit gives an almost powder coated look to your calipers.
A very good product , I like it alot and I would use it on my next car as long as its brakes are worth showing off

I didnt take a before picture of my actual calipers .. I forgot too, but this is what they did looked like :
And now This is how they look now :
