1996 Ta Center

Once the rear is centered, the car is moved over to a four-post drive-on lift (or you can crawl under the car as the suspension has to be loaded), in order to measure the driveshaft, lower control arm, and pinion angles. Jeffery says, "Although we measured the driveshaft and pinion angles, the difference (driveline angle) is irrelevant. In this case, we measured 2.2 degrees of down pinion angle, 5.1 degrees of down angle on the driveshaft (results in 2.9 degrees of driveline angle), and 1.8 degrees of up angle on the lower control arms. The torque arm that was previously at 2 degrees was modified slightly to adjust the pinion angle to 2 degrees, allowing us to achieve a preferred pinion angle and an instant center on the torque arm." Once the adjustments are complete, the underside is inspected as a final check, and the car is lowered and driven off of the lift. After reinstalling the negative battery terminal, the 'Bird is ready to assault the track and test out the effectiveness of the component and chassis tuning.
