First of all, I wanna say that this is a first skin for SBR4 ever! Ok, this one contains changed .jbeam file for SBR4 - i added a line for Paint Design - so now you can change its livery in Parts Manager. It works like livery e.g. on Sunburst, but now it has only one skin. The best color for this livery is Brilliance, that is placed last in selector under image. To install, just place .zip in /mods. If i`ll beat my laziness someday, i`ll try to make a light bar for this. Spoiler Hint: you can take my Jbeam and place it in /mods in a separate folder for having Paint Design option on SBR4. Also be awared that update can break this thing, cause it changes Jbeam.
