as long as you can fully turn off the brake LSD/stability control/help, I'm fine with it.

its fully defeatable in my Mustang, so I don't see why Ford would make a car like this and not let you turn it off fully. I freaked out a little about this initially, but now that I've thought about it, chances are slim that Ford won't make the system fully defeatable... lets just hope they don't pull a VW here

I would suspect the system will always be at least partially there. Maybe with ridiculous wheelspin/yaw tolerance, but still at least watching and intervening a bit here and there.

it lets me go wild on the mustang... and you can really tell the difference

they can keep the torque vectoring system always going, and I wouldn't be surprised if they did, but turn off the brakes please

Well, on both the Focus ST and the Fiesta ST, traction control (and pseudo LSD) is fully defeatable, torque vectoring is not as to them it's a different system and is what helps those two FWD's handle so well. I would agree with them from my experience with my Fiesta ST. The torque vectoring works well and does not destroy brakes if you have the traction control system fully off.

For the total purists you can purchase a "race" ABS module from Ford racing that deletes the torque vectoring on the Fiesta ST. Not sure if the Focus ST also has this option.

yeah, In post 573 (not sure if you saw it or not) I mentioned that I'd be all for leaving the LSD torque vectoring in affect but making the brake portion fully defeatable...

and weren't bigger brakes one of your first mod for your Fiesta ST>

Just so you know the "brake" LSD and torque vectoring are two different things but both use the braking system. Without the brake portion, they would not exist, they are not mechanical.

The RS steps it up a level and has mechanical torque vectoring in the rear, much like the Evo 10.

Thats what I'm talking about, leave the mechanical diff clutch controlled stuff going, but make all brake assisted stuff defeatable.

I'm only talking about the RS and what was posted about its AWD system. My only comment directed about the Fiesta ST was about bigger brakes you put (in case it sounded otherwise)

just started watching the xcar vid Robevo posted above, the guy in there says it's torque vectoring system doesn't use brakes at all

Ah okay. Yes, it sounds like you can fully defeat the brake assist portion and purely go by mechanical rear torque vectoring. However that leaves a open front diff. (and rear)

So basically it would be like a Golf R with nannies turned off but with rear mechanical torque vectoring. (MK7 Golf R has brake torque vectoring)

not really. it has hydraulically controlled clutch plates in the diff (at least the rear) so it can do torque vectoring without using the brakes

at least thats how I understand it from the RS's awd system breakdown thing you posted in post 568

You are stating the same thing I stated. Nannies off, rear mechanical torque vectoring.

However that leaves open mechanical diffs front and rear since there is no pseudo brake LSD action going on anymore.

Thats been known from the start. The worry is how long will those clutches last. Also they aren't on all the time, it's sort of an emergency aid on the street as it will take some gnarly driving to activate them from what I have read.

Driving down the highway or in town the car will be fwd and it is sensing conditions 100 times a second and can turn into AWD at any time.

you said it'll be the same as the golf r and that the golf r uses brake torque vectoring... I was saying that the RS does not using brake torque vectoring (my best guess is stability control)

Do you also worry about how long the rear clutches in the torque vectoring rear diff on your Evo 10 will last too?

No, I stated with the nannies off, it will be like a Golf R with the nannies off, meaning, open diffs front and rear as both use brakes as pseudo LSD units.

According to that sheet I posted, the Focus RS "to optimise handling and stability, the car's brake-based Torque Vectoring Control is tuned to work in parallel with the torque vectoring AWD system" which probably means it helps torque vector the front in conjunction with the rear drive unit mechanically doing it, which I personally think is pretty awesome, if true. However, the sheet I posted talks about the rear of the car overall, so front is probably just the brake based pseudo LSD.

At least that is the way I understand it with the *very* limited information we currently have.

I'm fine with having a discussion over the system but really not interested in arguing over it.
