This a bit of an odd car for one to race but this the PureDrive Motorsports GT3 car which will race in the 2018 24h Hankok Dubai race(in the end i didn't see it). Thanks to @Mankiewicz , i have been able to fix the problem with the banner. And for those who want to paint the sunstrip name it xxaltWINDSHIELDOUT (for the outside) and xxaltWINDSHIELDIN (for the inside).
In order to install the skin you have to go to your rfactor 2 folder is located and then go to user data >player >settings >Radical_RXC_GT3_2017.
