    All Wheel Steering Demo Vid

    Figured I'd post it up again for those that haven't seen it.

    Tested with a 1994 3000GT VR4. AWS is pretty visible in this video when I turn full lock. I turn full lock twice on each side, which is why you see the wheel pop out twice. At around 3/4 of the way through the video I'm jerking the steering wheel back and forth, and you can see it activate then as well.

    The AWS system is same phase, meaning the rear wheels turn in the same direction as the front wheels when it activates. The AWS is controlled by a system of valves at the rear differential. There's a valve that limits the AWS to above a certain speed, so it doesn't make parking more difficult. There's also a valve that activates the AWS based on a pressure differential from the two feed lines from the front power steering rack.

    The system is extremely stable for lane changes, and helps keep the rear end in check in corners. Professional drivers that have tested the AWS through slaloms say it makes the car feel "different" but they say it's also easier to go faster because the rear end doesn't slide out like it would with no AWS.

    Notice the Active Aero front air dam in the video. It pops down at around 48 mph.

    disclaimer: I am in no way responsible if you try this and do something stupid or hurt yourself, etc.

    That's always cool to see. ...I'm just too afraid to do it on jackstands.

    Eh, it's super stable. I was just dicking around with it yesterday because I had her up on jackstands bleeding the brakes. 6th gear at idle doesn't make enough power to not eventually stall, for future reference, lol.

    Is it possible to alter this valve or modify the system to make it active all the time? I've never looked at the service manual for this system.

    Would performance be better around turns when deleted the AWS all together.

    I'd imagine you could, but the rear pump is driven from the rear diff, so it would need to be modified to pump using an electric motor. Plus, it would be kinda pointless at lower speeds. bluemax_1 made a great post on why the AWS works like it does. I'm gonna look for it, or have him post it up again.

    Depends what you mean by better.

    I love this vid because it shows a cool feature in operation. Makes me want to keep all the original "stuff" working as it should

    @Atrosity - I would keep it connected and repair it. I haven't had enough experience with one deleted vs undeleted but from everything I gather from knowledgeable individuals, even though it's speed dependent, having AWS is a benefit in road racing.

    I'm keeping mine for sure.

    Eric, just make sure you haul a$$ through the entire track to keep it running
