Higher Grip

Since the grip levels were changed a while ago, is there anyway I can increase the grip of vehicles or the ground?

 

Create new tires. Just copy existing tires and change up the values, and make sure names don't conflict. "gripCoef" is the thing you'll want to make higher.

 

what values would mimic the old grip best would you say?

 

I think the "gripCoef" you could actually keep the same or even add just a tiny bit, but the "slidingGripCoef" you could add like .5 or .75 to

 

Old tires were wider for tire_R_205_65_15_race:
Width 0.200, while new one has width 0.185 (more accurate)

Spring values in old tires are less, especially sidewall.

Grip coef is 1.34 for old and 1.3 for new, but there is new slidingCoef that is 1.25.

Then there is new values that did not exists in old tires:
{"noLoadCoef":1.46},
{"loadSensitivitySlope":0.000172}
{"fullLoadCoef":0.44},
{"softnessCoef":0.8},

Reducing effect of load sensitivity would be needed to get old behavior back.
