A great addition to any S550 Mustang. It’s very straightforward, it was my first time doing a side skirt installation and it was completed in an hour. As well it’s great quality and looks nice.

I was skeptical buying this because its cheaper than the others but hey it fits perfectly and the quality is good. I highly recommend this one!

Easy to install, I would use push fasteners or rivets instead of the screws they send you in the kit. With vibration and over time I’m sure they’ll work themselves out
