I've seen quite a few people struggle with getting their crc paints to have the color of suspension or 4links that they want. this is because crc is quite different from crd in the fact that theres often 2 materials file types instead of just the one. With this template file you should be able to use FNR to pretty much every instance of CRC_Colored_Parts_Test to be what your paint will be called. From then on its as simple as changing the body if required. But by that point I'm assuming you know how to do that by watching CRC Easy Skins or just general practice at making paints.
This file has all the main parts colored; suspension, Clark rim, hydros, axles, swaybars and limit straps. But I've also gone a bit above and included even lesser used bits like the steel plating on the truck floor and roof and the exhausts. All the way down to even some silly parts like the Lexan and even the blower straps and belt.
This isnt a 'replace every texture file with a pink square jpeg' either, it is actual colored bits. its not every single part of CRC, but its most of the important and noticeable ones.
