How many people scale there cars?

I am interested in how you figure down force at speed. I know John's liner has the engine in front of the front axel and was wondering if there was something unique to that combination that was giving him an unusual number.

110% is fine if you are young or take little blue pills.

Yes aero downforce on the tail to overcome possible low pressure under the nose . In 5th gear maybe it's 95/20 .
