It was done old-school way...
One "owner" was an exec at the local Toyota dealership.
For shits and giggles, he brought out a brand new Tercel - very soft suspension with very tall tire profiles.
The autocross track was VERY rough and uneven - old airfield tarmac.
White shoe polish on the sidewall
Bump up the pressure until traction was OFF the sidewall
Nothing fancy
Us newbs were just horrified with how high the (hot) pressures were.
He comforted us saying that he's run tire pressures up to 80psi on very heavy Supras on the autocross course.
Scary...but you can't argue results.
