I've created this topic for the MSC players in this forum. We can discuss how broken the Unity physics are or each others Satsuma's problems or experiences with the game or anything really!
Personally I haven't really ever had issues with the Physics, other than if something glitches and causes everything to just have a heart attack. The only issues I have really come across is with the DonnerTech Turbo+Ecu mod producing just too much power. You'll spin wheels all the way through 1st-4th. I also play with a steering wheel and it's still hard to keep under control. It also makes the clutch super sensitive and glitchy too for some reason, had to put on stock flywheel for it to even be slightly driveable. The Ferndale is also pretty much just USELESS on dirt roads at this point.
I also find it sad how many good mods are broken and not getting updated - the house lifter, pit cover etc.
Also unless you were wondering I managed to do a 9.5s pass at the drag strip on the turbo (not played in a fair moment so might not be quite correct)
