The Dinka Blista Kanjo from the Diamond Casino Heist update converted to GTA IV with most tuning parts kept and fully usable, along with a moving steerng wheel and all liveries.
I've included the .max project file for anyone who wants to make their own fully tunable car.

REQUIRES v65.0 or newer of Zolika1351's Trainer/Mod Menu to work, otherwise the car is completely unusable. v65.1 or newer recommended to avoid some instability.
PUT KANJO.DAT INTO THE "carmods" FOLDER! (if it doesn't exist, create a folder called "carmods" in your game folder and put the .dat there)

Use https://gtaforums.com/topic/955449-iv-zolikapatch/ to make the steering wheel move and unlock the 4 livery limit

WARNING: This car might still be unstable as it's pushing IV to its absolute limit with 87(!) separate tuning parts spread across 9 categories.
