this mod is decent as a fun little addon and i had a good time playing it casually but if your expecting an amazing time its not the one, great to play around with the teams and do a career but there are a lot of problems.
1. even at the lowest revs your car is at redline meaning that you cant complete a 50% race without my engine overheating
2. you cant complete a lap of a few tracks for quali as you run out of fuel before the end of the lap for some unknown reason.
3. the liveries aren't mirrored properly so the left side is backwards
4. it crashes your game quite a lot
other than that id give it a try for a few hours of fun
