OK. I hope I have the Buick sorted.
Default setup is 50% on all settings so probably not something you would race with, especially on an oval. This could be changed to a very generic road course setup if a tester would be so kind as to make one.
Each setting has plenty of room up and down.
No rear toe or camber as I finally sorted out the 'truck' rear end.
Engine has a redline at 8000 but makes max power at 9000 and then sfa.
Above 8000 you start to take damage but at a low rate. It will take many 10s of minutes to blow your engine.(subject to testing)
Idea is to roughly set your solo top speed for 8000rpm then in a tow you can use the overhead.
