Hi! these are 2 cars which I found the sound to be possibly bugged. Adjusting my Number of effects setting did not solve the issue. 1. My Kartsim T4 kart sound crackles when the suspension moves, each time I turn the wheel. The tire rolling sound might also be too loud. The engine sounds low compared to what it should be, and there is always loud dirt/debris sound effect when driving. I do not hear these issues with the other Kartsim karts, the X30 and Rental. 2. The MCR Sports 2000 of the Reiza pack has very low engine volume from inside the car. I can barely hear it, compared to opponent cars. My car sounds louder in replays. In car, it sounds quieter than other cars. Thank you!
