The stock differential provides 2:1 torque distribution, with the modified STaSIS unit we’re able to provide 4:1 just like the B7 RS4.

I have not had a chance to take the car to an HPDE yet, but I have noticed an immediate difference coming out of the apex of a corner. Typically when you’re exiting, the car begins to under-steer; with the diff the moment you begin to under-steer the power is transferred from the front to the rear and we can neutralize some of this under-steer.

There has been no odd behavior from ESP or ABS. The only thing I’ve noticed post-diff has been some Quattro binding at low speed turning, such as in parking lots.

This modification is available for 5 and 6 speeds, manual A4/S4s.
