All Whel Steering model years?

lol why would that put all wheel steering to help for parking... its for handling man. Its only activated at 30mph+ is what i heard.

Definitely not. It's designed for higher speed, and track usage.

They didn't discontinue it in the JDM models, as i got a 99 GTO with 4ws/aws, however the MR's dropped this feature

Speaking of which, do anyone have a link for a AWS delete? I think I want to take mine out.

BTW, it's easy to tell if you have AWS or not. Does your car have rear steering rack? You cannot miss it, it's big

Wrong - My '92 Stealth RT (N/A) has ECS.

Our cars wern't set up to have it help with parking and low speeds but other cars have been. A few years ago their was a truck that had it, helped with turn radius and parking but drivers who owned the truck kept hitting other cars in parking lots so they got rid of it.

A few things about AWS.

Yes, it only activates at high speed.
Yes, it was originally intended mostly for smooth highway lane change maneuvers.
Yes, the maximum change for the rear wheels is only 1.5 degrees.
Yes, it is same phase aws so the rear wheels turn in the same direction as the fronts.
Ours is hydraulic, not electronic. There is no significant delay. Basically, there is a pump/valve that basically controls when the rear wheels can turn based on the speed the car is going (can't remember where it's attached to the rear drivetrain). When the pump is turning fast enough, hydraulic pressure from the same circuit that the front power steering is connected to will turn the rear wheels will turn when the front wheels are turned.
NO, it does not take 4-5 seconds for the rear wheels to initiate the slight turn.

The shop manual's procedure for testing the AWS is to lift all 4 wheels off the ground, get the car up to 50-55mph with the wheels spinning in the air and then have someone turn the steering wheel. You should see the slight change in angle of the rear wheels. (I still wonder about this one. The idea of having my wheels spinning at 55 mph on jackstands...).

BTW, there were some Japanese cars that had opposite phase AWS where the rear wheels steered in the opposite direction the front wheels were turned. Nissan's Skyline GT-R's (where it was called HICAS and later, Super-Hicas) were probably he most well-known of these. Some 300ZX's also had this. There were also some Preludes that had a similar feature for a short run.
