This method lets you measure and adjust all four wheels. Measuring the front and rear separately may work on a new car, but a hard-driven car may have a shifted frame. Measuring and adjusting all four wheels together helps establish a setup that drives straight. The homemade tool shown above uses two 460 mm U-shaped aluminum bars, crossed and fastened with brackets. Bolts at the four ends let me level it against my 15-inch wheel, using a 400 mm diameter. Double nuts hold the bolts in place. The bolts must be long enough to extend beyond the rim. A vertical bracket at the center of the cross holds the laser 205 mm above the ground. The exact height is flexible, but this is convenient. Lasers are available at Tokyu Hands.
