Description
What It Does
The most common failure point on the Audi Sport Differential is the pair of spider gears at the heart of the differential. These gears take 100% of the torque delivered to the rear end. On higher powered and/or heavier cars, it’s common to see them break during launches and 1-2 shifts, usually destroying the casing and ring/pinion gears in the process. Photos below. The 4-pinion upgrade replaces the stock differential with a stronger unit utilizing 4 spider gears instead of 2.
What'S Included
The 4-pinion upgrade is offered in 2 ways:
