Had I known about these I might have considered them, but I don't regret my ACS guards. To me - the rear cover just enough, and the front work well enough, even though they may not have the protection of this product. I prefer the finished look of the ACS, rather than most of the other offerings. If there was one think I didn't like about the 5th Gen ZL1, it was the textured plastic rockers and splitter and such. It was just un-finished. I like they changed it with this generation, and felt like the ACS guards just complement the car.

With my ZLE, I went with the ACS Composites. With the black trim pieces from where the diffuser wraps around at the bottom behind the rear wheels, the ACS has a pocket built in that slides over the trim so there is no gap. It fits nice and flush. I believe I read where the zl1 addons will have a small gap that some people fill with black silicone or some sort of filler. Also, the rokblokz look flat and will not necessarily fit flush as well.
