Yes, the coefficient of friction (“grip”) is probably not far off. However the perceived grip is far too low. Why the difference? Real grass slows you a lot more than iR grass, which helps keep you from sliding 500 yards at full speed into walls and allows you to regain control faster as the car slows to a controllable speed. Real grass also gives, resulting in a tendency for the car to sink in and travel in little ruts (this also causes extra drag and more loss of speed – especially for low cars), this helps stabilize the car (thus little tendency to do donuts at 1/10 throttle and 2 mph trying to get back on track.).

Does iRacing figure in if say 1/3 of the tire is in the grass (or above) and 2/3 is still on the pavement? A lot of racetracks, the car could be over the edge of the track, and still be above the grass (stiff tires).

Nice reading! I’ll surely direct someone to it if he’s asking about tyre grip on grass.

So you were in the middle of the field smoking grass and you had the epiphany that the friction was right after all?

A very interesting read! Thanks for writing it up and sharing.
