Hmm, I haven't seen a "Base Rubicon Spec Sheet", is that on the site here or did you dig it up elsewhere? I gotta see it now. (c: Do you mean for the Wrangler?Eternus, the mold-in-color two piece flares are black not colored like the name would imply. Seems a bit odd but that is what is on the base Rubicon spec sheet and the only place I could find that terminology used. My guess is they are Rubicon width with the standard height to provide adequate tire coverage with the wide track axles. Cool stuff!
