The downside to most aftermarket fender flares is: A.) any required drilling into your truck’s metal, and B.) they always tend to rust in a few years due to scratching against metal, drilling, and holding on to water.
That being said though, I like the blacked out flares and have thought about it for mine. I wish I had the TRD OR on the sport. The color keyed looks good but they have already gotten scratched up a couple times.
