We would pay Slee to do it if we had to do it again. It was a pain in the butt! The price they charge in labor is worth it. The instructions weren’t that intuitive. We bought the rocker panels from Groove Toyota but didn’t need to buy any extra clips for our 2013 LX570.
Slee suggested buying a set of LC rocker panels rather than cutting the ones on the LX for a cleaner look. I ordered a set that should be in around Thursday.
