You guys... I used fishing line to set-up every race car I serviced including GT 40's Formula, Indy, etc.
Make sure car not bent/broken. Measure wheelbases side to side.
First is to set your corner weights and ride heights. Disconnect sway bars, one end loose on front and rear bars. Use a laser or water/clear tubing and floor tiles to get all four scales at same elevation. Get your front/rear, side to side bias and ride heights close.
Next. Jacks under front arms and set your camber. Use jacks to get the tires off ground to swing lock to lock with camber gauge. Get your camber gains. Compare to tire wear after thrashing. Shoe polish marks on sidewall gets air pressure right. If not, you need camber change.
Use 4 heavy jack stands (we fabbed stands or a bar to look important) and fishing line. Make a "U" with fishing line wrapped around jacks that car fits in. String height near center line of wheels. Check to make the "U" is square by matching diagonals. Metal yardsticks from string to edge of rims. Toe settings for front and rear. Roll car in and out of "U" to settle changes.
Insert driver and spend weekend screwing it up.
