Limited Slip Diff & Traction Control

[RichieRocket]

I was hoping the Sonic would offer optional limited slip diff, 'posi-traction' or whatever they call it now. I really want it more for driving in the snow, both tire pulling would make a huge difference!

Especially for hopped up engines with 200hp, an open diff will just burn one tire. The old 'sit-n-spin'...if the traction control is turned off.

How does the traction-control work?
If one tire starts to spins, does it
a) pull back engine power
b) apply the brake slightly on that side to feed power to the other side
c) something else I'm not thinking of?

You can buy aftermarket for it. Quaife alrwady has one out for the Sonics transmission

Yeah, but an aftermarket posi would require pulling the tranny out of the car and tearing into the thing...right?

I guess it depends how the traction control works would dictate if it's worth it. If the stabilitrac system can apply individual brakes for a wheel that's excessively spinning, I could live with that...I'm not going to drag race the thing.
BUT if it just cuts power, that's gonna suck...

Getting the limited slip and getting it installed would cost you about 8-1000.

The Quaife unit is about $900, probably more today as the dollar weakens.
My understanding is the differential can be changed without removing the tranny, but I would allow for about $500 for a shop to make the change.

The Corvette Active Handling functions to modify power and apply braking to a specific wheel to maintain handling, and I suspect traction control, four wheel ABS and electronic stability control work together to that effect.

Stop! No! You are making me have evil thoughts...

"Well, I could just do a reflash tune and install a posi diff"

I should just keep it stock and get my adrenaline rush on the race track on my motorcycle.

Although I still want posi for snow driving...
