I will soon... It is the best model of the car for AC that's for sure. I have been in the process of updating it though. There were many issues with it like broken collider, aero improperly configured, inertia completely wrong, copied suspension geometry and so on. There is plenty of specification data for the car as well for JDM parts used in the S1 version so I am in the process of implementing it. Here is some of the original credits for the car:
"Model - Turn 10 - FM4
Conversion, 3D, Textures - Jack Thorpe
LossTunes (Stereo)
Wack (Removed the bastard sunroof)
Kunos (Some shaders, exhaust model, seats model, brake discs and calipers on S1 version, license plate)
T10 (thank mr t10 for discontinuing the JDM DC5)"
