Install isn't the easiest thing I've done as these are really meant to easily fit on a Z06 or grand sport but the carbon fiber is fairly easy to trim. I had to trim both the front and back to fit within the ACS composite XL mud guards and the apr front splitter with the winglets. The key is to take the time to measure and for safety's sake left a little on and the trimmed as needed. I also found because of the winglets already bolted on using the OEM bolts in the wheel well that I needed to buy slightly longer ones to fit both the spat and winglet in same spot. Overall happy with the look. I bought my via extremeonline but there available pretty much everywhere but that happen to have them on sale.
