In CustomPhysicalProperties there is a property called friction, which is very helpful for vehicle’s (which I’m currently working on), but its limit is “2”, which is a bit annoying…
Is there any way to exceed this limit?
Thanks for any help 
From the testing I did, there seems to be no way to exceed the friction ceiling of 2. However, one thing you could do to increase the effects would be to increase the associated FrictionWeight value in CustomPhysicalProperties, since this seems to provide a similar effect to what you’re looking for, and it has a much higher cap of 100.

What are you trying to accomplish with increasing the Friction?
If it’s something like making wheels have more traction I’ve used a trick where I make all the Parts of a car Massless except for the chassis Part, which I tune if the vehicle has suspension, and I make all of the Wheels Density greater. You may need to increase the Torque of the Motors involved, but it can help.
Also you can increase the Friction of the road surface Parts as well.
It may take a bit of time to fine tune something this way, but I change the Properties in Play mode in Studio, then make the final changes to the Properties after I hit Stop.
