tho once its gone you find out fast how much of a pain it is to park such a big car in small carparks without 4ws

Mine has HICAS , but I still find parking difficult in small car parks . Should I get it looked at?

i`ll say again, HICAS does not work at low speeds for example when parking. Can someone please clear this one up

[Squeak]

I'm sure so Jay. Plus the rear wheels movement is so minimal (1 degree) it wouldnt ever effect slow speeds e.g. parking.

Someone had best start learning to park I reckon


Some more friendly info..

HICAS is the acronym for Nissans rear wheel steering system named High Capacity Actively Controlled Steering. HICAS works using different sensors which calculate speed, steering angle and corner position the rear wheels are steered by a maximum of 1 degree based on these measurements. HICAS helps eliminate body and give the car a more nimble fell, it does it job well and is helpful for the average driver who doesn’t push the car to its limits.

On a racetrack however HICAS becomes to intrusive and unpredictable, particularly on long high-speed corners, counter-steering is often needed to correct the Skyline though the corner, this is not good for lap times. Race team’s usually use a lock bar to disable the HICAS system which improves the Skylines balance, resulting in more predicable handling and faster lap times.

Earlier skylines (the R32) used a hydraulic system which had speed sensors and used the power steering pump to steer the rear wheels. The newer version named Super HICAS was used from the R33 onward; electric actuators were used a long with a onboard computer, this version saved weight, and is said to be a much improved system.

This happened last time I tried to park . The HICAS was no help at all.

From reading this thread it seems if you drive " spiritedly " it seems better to have the hicas locked out with the bar.
Does hicas effect wet weather grip ? The reason i ask this question is that my hicas system works , but the ball joints that connect into the hub are dead. So i'm about changing them , if i decide to lock hicas out with the bar is there another option , instead of the ball joints ?
Must admit with hicas working, at speed the rear end does seem stable when cornering. The only time get the " rear end wiggle " is in the wet.
i don't do track days yet .... so it's really used fast road.
