I'm using 2.3.0 LE "vanilla" and it works fine.
The only time it crashes is when there are white shadows on the 'fake' racers (happens 1 in 100 times while racing, so it isn't really a point) and when losing a part while you're in the garage. (if you have a bumper at 5% and remove your wheels, so it bangs on the floor, it will crash)
I now have a career where I bought the racespec baiern (capable of having a v12), sold everything of it (except the chassis) to buy a Ishima WR superturizmo. (capable of handling a V10)
I fixed everything, then I had to sell every part of my cars (except of the chassis' to buy a Prime 500 with high-revving, 800BHP V8 (capable of handling a V12) (is that what it is called))
Now, I have three cars, one with an inline 6, one with a v8 and one without an engine.
They will eventually be upgraded to 2 v12s (3000+BHP) and 1 V10
