I used a tape measure,a square,a nut on the end of a string and four tiles facing each other with sand inbetween. You can find measurements online or in your FSM. You set the car down on the tile on a flat surface, the sand allows the tiles to turn so you get real time adjustments. Measure front and back of front tire and adjust to spec. Tape string with bolt to fender and use square and tape measure to set adjustments. My 10 yo helped me had it done in an hour and i got about 3.5 years out of the front tires.
