Another vote for the PSC inner liners - I bought the non powder coated and painted myself . Straight forward install - In this pic I installed the shocks, Metal Cloak Fenders and the PSC liners at the same time - everything is still nice and shiny. Dont see a need to install the rear liners.
I bought my inners from Crawler Conceptz a couple of years ago before there were so many other options. They were one of the first I saw that looked good to my eye and were willing to sell me a set that didn't provide free advertising for the company. I'm not crazy about a bunch of logos. I got them bare and had them powder coated black with the screen close to the body color. The XRC flares that came with my Jeep really need inners. I just used black truckbed rattle can for the rears.
