4ws (4 wheel steering.)

But it's a little different.

I think that below 60 or 80KM/h the, when you turn the steering wheel to the left, the rear wheels go in the opposite direction.

Above that speed (say like on a motor way) the rear wheels turn in the same direction as the fronts.

The rears don't turn as much as the front.

It is a very tiny amount..

It is almost impossible to see but when you drive and turn a corner or change lanes on the road, you sort of feel like it floats .... very unsettling when you first drive a car with HICAS.

The old Honda Preludes had 4WS but the rears on those turned heaps..

HICAS (on the R32 skyline is the only one that I can say cause that's what I have) is different.. it is not as noticible.

HICAS only comes into affect above 80KM/h. It helps the car turn in better into corners. It only turns 1 degree in which ever direction the front wheels are turning. So it's not visable like the Prelude or MX6 4WS. Also there is no mechanical link between the front steering shaft and the rear, unlike the Prelude or MX6. It's pretty much software controlled.

However for maximum handling, and for those who know what their doing, removing the HICAS is better as it gives a more consistant handling.

HICAS stands for High Capacity Actively controlled Suspension.

It's designed to make high speed (above 180km/h:) ) handling better, it only turns the wheels a maximum of 1 degree and only works above 80km/h.

It works on the idea of rally driving, it actually gives the rear wheels a twitch of counter steer before turning the same way as the front wheels.

On my Zed it's hydraulically controlled, later ones went electric.

I've removed mine and have noticed no difference whatsoever in the handling

ok i dont really think it's worth all that effort to take it off if you can't really notice it..

I have noticed lately that sometimes when i chuck the car into a corner n try to get it to slide it will jsut start spinning the inside wheel rather then flick out like it used to..

Anywone have/had this problem???

    • I'm back from the dyno - again! I went looking for someone who knew LS's and had a roller dyno, to see how it shaped up compared to everything else and confirm the powerband really is peaking where Mr Mamo says it should. TLDR: The dyno result I got this time definitely had the shape of how it feels on the road and finally 'makes sense'. Also we had a bit more time to play with timing on the dyno, it turns out the common practice in LS is to lower the timing around peak torque and restore it to max after. So given a car was on the dyno and mostly dialled in already, it was time for tweaking. Luis at APS is definitely knowledgable when it came to this and had overlays ready to go and was happy to share. If you map out your cylinder airmass you start seeing graphs that look a LOT like the engine's torque curve. The good thing also is if you map out your timing curve when you're avoiding knock... this curve very much looks like the inverse of the airmass curve. The result? Well it's another 10.7kw/14hp kw from where I drove it in at. Pretty much everywhere, too. As to how much this car actually makes in Hub Dyno numbers, American Dyno numbers, or Mainline dyno numbers, I say I don't know and it's gone up ~25kw since I started tinkering lol. It IS interesting how the shorter ratio gears I have aren't scaled right on this dyno - 6840RPM is 199KMH, not 175KMH. I have also seen other printouts here with cars with less mods at much higher "kmh" for their RPM due Commodores having 3.45's or longer (!) rear diff ratios maxing out 4th gear which is the 1:1 gear on the T56. Does this matter? No, not really. The real answer is go to the strip and see what it traps, but: I guess I should have gone last Sunday...
    • 310mm rotors will be avilable from Australia, Japan, and probably a few other places. Nothing for the front can be put on the back.
    • The filter only filters down to a specific size. Add to that, the filter is AFTER the pump. So it means everything starts breaking your pump even if its being filtered out.
    • Just like in being 14mm too small (296mm) makes it not fit, being 14mm too big (324mm) it also won't fit. You want to find the correct rotor.
    • @GTSBoy Ok so that was the shops problem...they showed R33 rotors on R34 page and i did not know 296 do not fit(and are for R33) Yes i bought "kit" with rotors and pads. Pads are ok(i have GTT calipers front and rear). They have some 324mm but no 310mm. So i dont know if they would fit. I have 17inch LMGT4s So another question. Can i fit those in the rear or they are just "too" big for that?
