I like it. What did you use? I used a white Water based Paint pen for the Nittos on my GTI. Was debating doin the Ty, saw they also make stickers in White also.
They are actually about an 3/32 to 1/8 in thickness. They are basically rubber decals ( actuall rubber) that are glued on. You can get them in most colors and just about any lettering you want.
Can remember the spelling of the top of my head but I think it's tiregrafix.com
