Help! F1 2008 mod has weird white textures!

I just installed this awesome looking 2008 mod via CSM. I tried to play it in the game but the inside of the cockpit and the suspension are all covered in white for some reason. What am I doing wrong here?

missing textures for the suspension, prob called hi_carbon or something like that, open the cars.wad and with gp4 builder have a look for the Tex file name and then make sure it is in the cars.wad
