As far as the 'why have you done a HOW TO on applying a decal' comment I think you have to appreciate that because you may have experience using them some people may be unsure. I had never used them until I put brembo decals on my painted calipers Yeah they are pretty straight forward but whats the harm of having a how to for people who are not familiar. Changing brake pads is a walk in the park for some people while for some its not. All I am saying is the poster has took a little time to try and contribute to the site and hes being shot down - for what reason I am not quite sure..
As for putting the nismo decal on - i think its a nice touch and know plenty of people on here who have did it - if you have nismo products whats the biggie. Just my 2p.
