We do not use (or supply) a thrust bearing with the car. A thrust bearing hinders the diff action on the car due to the excess drag.(Thrust balls are sandwiched between washers which= drag). With using the flanged bearing as the thrust, there is almost zero side load as it uses the inner race to rest against and doesnt restrict rotation as it is tightened. The thrust bearings are great for use in club racing where you dont want to change the flanged bearing after a big hit. The thrust will increase time between rebuilds but when it comes to performance of the diff, the thrust bearing does hurt performance against a flanged bearing. This is why it is left to the consumer to make the decision if they want to use one. Hope that helps buddy.
