In possession of headliners from both SOR and Cruiser Corp and thought I would pass on the difference between the two. SOR advertises as super thick....I measured it as 6.80 mm. The Cruiser Corp measures 4.80mm. To show the difference in color I have them staged with the bezel painted cygnus white and some plain white computer paper. The liner on the left is SOR's and the darker shaded one on the right is from CC.
