Externally, the differential can be quickly adjusted to the track and traction with an external adjustment (18 positions). This has particular influence on the operation of the differential during turning and rolling in corners. This adjustment is possible while the differential stays inside the car. This can even been in the pit street with the bodyshell mounted... It is advisable to adjust only 2 positions until the desired result is reached.
 
Finally, the locking effect of this new Bergonzoni differential can be influenced by the use of thicker or thinner oil. Especially with higher temperatures and high grip a thicker oil will be better.
 
The differential already comes filled with oil (recommended amount of 5ml)
 
Weight 218 grams (265 grams with differential gear)
