Re: halving the range of wheel->lfMax and wheel->lfMin

Hi David

You can set these parameters directly in the xml configuration of the 
car, no reason to fudge with the code, see wheel.cpp:
wheel->lfMax = GfParmGetNum(hdle, WheelSect[index], PRM_LOADFMAX, 
(char*)NULL, 1.6f);
wheel->lfMin = GfParmGetNum(hdle, WheelSect[index], PRM_LOADFMIN, 
(char*)NULL, 0.8f);

Look up the definition in car.h for the effective xml parameter name:
#define PRM_LOADFMIN            "load factor min"
#define PRM_OPLOAD              "operating load"

Kind regards

Bernhard
