The flaps keep the car much cleaner and look Fab!!.. They were easy enough to put on if a little bit off a footer. All the parts came in bags clearly marked. The downside to the kit, I had to change the plastic pins for that of M6 stainless steel screw bolts, and also had to get a couple of more washers to make sure all was sturdy. I also put some Thread lock to ensure nothing worked itself loose.. Some plastic locking nuts would have been good so as I didn’t have to use threadlock.. Last grumble is cost £130 is just a little bit steep….
