Hi all,

I'm taking my S4 in for the Stasis 91 ECU re-flash next week and I'm also thinking of getting the Stasis high bias torsen differential.

Anyone have any thoughts on the updated diff?

I think it largely depends on what kind of driving you're doing....canyon carving, track days, regular commuting, etc...

Stasis 20/80 diff not available for sport diff cars.

NickS

...and not available for DSG cars.

....and not available for ADS cars since it includes the sport diff.

I just wanted to pile on.

What about non sport diff manuals?

If you can supply me your diff. code I can tell you if it's compatible.

Nope!!

Why though?

Why turn an AWD car into (almost) a RWD car?

Seems like a step back to me, but I'm sure someone has good reasons to do this.

Torsen Differentials deliver more torque to the wheels that have more traction. The STaSIS high bias torsen provides a dramatic improvement in negotiating a turn quickly and efficiently. Now your car can be 3 cars in one(front, all and rear wheel drive):

Hard braking leading into a turn
Car acts like a front wheel drive – torsen acts like an open differential when its not under power. Wheels turn independently and car control is improved.

Mid Corner, Throttle On
Car acts like an all wheel drive– torsen delivers equal amounts of power to front and rear wheels. This maximizes grip, allowing more power to be applied at this stage of a turn.

Corner Exit, Hard Acceleration
Car acts like a rear wheel drive car – front wheel slip is rediced because the torsen delivers up to 88% of the engine torque to the rear wheels where the most traction is.
