The FPIU has a flipping issue but if you use the handling line from an SUV type vehicle like the baller 2 or Gresley it will fix it. I'm not sure where the issue is at but if you copy the entire handling line from top to bottom of either of those cars and replace the handling line of the fpiu with it you will fix it. These are awesome cars by the way.
Love the model but after installing it I noticed the spotlights glitch off and on when the light bar comes on even when I dont add them to the vehicle. Also the takedown illuminates underneath the car maybe it's something I did wrong I dont know
