DB18 Camber Adjustment
Posted: Thu Oct 27, 2016 8:38 pm
This article is written around the DB18, but the procedure could be adapted to other models.
The car should be parked on a level surface with the front wheels in the straight ahead position.
1) Use a 60 cm spirit level to establish a vertical reference line as close as possible to the wheel.
2) Measure the horizontal distances A and B: a micrometer capable of measuring internal dimensions is ideal; alternatively a steel rule can be used.
3) Roll the car forward and repeat the procedure several times over one rotation of the wheel. This helps minimise errors due to the wheel rim not being true around its circumference.
4) Measure the wheel diameter D.
5) Use the formula (A-B) x 60/D to calculate the camber angle in degrees. For the DB18, the wheel diameter is 450mm and the required camber angle is between 1 and 1½ degrees positive. This equates to an A-B dimension between 7.5mm and 11mm. The camber angle can be adjusted by disconnecting the upper transverse link from the top of the stub axle carrier and turning its outer end. One full turn of the outer end changes the camber angle by approximately half a degree.
