I just picked up the Nismo side steps for my '06 Nismo CC 4x4. I think the fit and finish is great. They are made out of aluminum with a rough texture. So they are light and the grey/aluminum finish will look nice with my storm grey truck. I read the directions and could not believe how easy they will be to install. No drilling. 8) The truck comes with 6 welded studs on each side. The mounting brackets (also nice quality) are designed with two holes that simply slide over the studs. Tighten down the supplied nuts and voila, brackets are mounted. The step rails simply are placed on the curved part of the brackets. There are mounting holes in the rails. Place the supplied boilts through the bracket into the rails and it's done. I'm guessing 10 minutes each side to mount. If anyone is thinking about side steps (tubes) I highly recommend the factory ones. If you don't have them, look under the edge of your truck for the mounting studs. My Nismo came with them. Not sure about non-Nismo trucks.
