driving with hicas

[macca]

I am in the process of looking for a r33, what is everyones verdict on the hicas. Do most people disconnect this setup or run with it. How difficult is it to disconnect. I am guessing it would take a bit of getting use to drive.

Any info would be greatly appreciated

thanx

hicas is only very slight turning of the rear wheels, i think the movement is 1 degree at the most. And im fairly sure it only starts working at high speeds

I feel it every now and then, and yes it is a little scary, especially if the road isnt flat and straight

I figure whenever u wanna go fast, cut the speed sensor wire and kill 2 birds with 1 stone no speed limiter & no hicas

I pretty sure you can buy kits to lock out hicas for under 200 bucks

It sucks if your going to do track work.

Your trying to correct the car in a corner and the car's trying to correct you. Tug of war that results in time loss. So that's why it's recommended that you remove it for track.

i own a 33 and have to say i have no problems driving with it when it activates above 60 -80km/h or whatever it is. But as is stated by Silver Arrowz if you want to do track work with it then my advice is take it off as well.

Day to day driving on the road you hardly notice it. Many people wouldn't even know it was there.

But it sure makes life harder if you are trying to maintain balanced power oversteer.

Not a real good idea to just cut the wire and disable it that way. Get a proper lock kit.

[CerealKiller]

a locking kit involves a bar which removes the hicas pneumatics.

You can also get the tomei lock kit, which doesn't.

I have the Tomei Lock kit, which has the brass washer looking things, and some sort of gdaget that is wired in and fools the ECU, just been to lazy to get it installed.

The Drift battle mag in front of me has em advertised at hi-octane for $245.

I got mine for half that 2nd hand.

Skylinegeoff also has the lock bars for sale I think?

[Sciby]

If SkylineGeoff doesn't have them, UAS has them.

i personly dont like the idea of a computer controlling my back end when im going fast around corners, so im gonna remove it as soon as it arrives.

It's not actually that bad, and since you've got an R32, it'll be hydralic, not a computer. Make you feel better?

It's a very subtle thing... the rear wheels deflect maybe 1 degree... but when you reef it around a corner at 70-80, HICAS tries to sort out what you're doing, not thinking that you're being a hoon, and tries to save you from destroying yourself... which you're trying to do on purpose, so it can be a little... frustrating. The worst it does is gives the bum end a little wiggle when cornering hard... which like it was stated before, sucks on a track.

I've got the Tomei locking kit and my Hicas warning light still comes on whenever I'm pushing it around a corner. I'm going to grab a Kazama lock bar to make sure it's hicas-less...

well i have a R31 with HICAS and it works even when stationary, dont know about later models though. Just looking at it and turning the wheel you would think it aint moving but it is.

As stated above, with normal day to day driving you would not know it is there.

But when I am driving around a long sweeping bend at speed it starts to wriggle the arse end about which feels very hairy. I also plan to remove it.

When you get the car, find a roundabout and start driving around it, slowly increasing your speed. At the start you feel in control of the car but as you get faster you feel the hicas come into play and try to work against you.

[KILL HSV]

so when you're going around a corner at high speeds, the hicas tries to correct the car for you? has anyone crashed from this? People who have had both, hicas and non-hicas, which feels safer for road use? and is the r32 gtr super hicas much different?

[cul202]

HICAS on an R32 is inactive at low speeds & fairly passive most of the time. It doesn't so much correct you, its more about aiding more responsive turn in and increasing stability mid corner.

/searches for diagram from R32 brochure...... fails

Basically:

At intermediate speeds it will angle the rear wheels opposite on inital turn-in to to sharpen the turning response, then angles them the same way as the front for mid corner stability.

At high speeds it does the same minus the initial turn-in opposite angling, the idea being that at higher speed you need less turn in response.

Unless the system is playing up or you entend on doing a bit of track work I really wouldn't worry to much about it.

[awurth]

the hicas is fine. I can understand people locking it out someway for track work but for driving it's no drama's. You'll find if you try hang the car sideways it'll start to kick you straight, kinda driving you out of the corners.

[Sciby]

I've got the Tomei locking kit and my Hicas warning light still comes on whenever I'm pushing it around a corner. I'm going to grab a Kazama lock bar to make sure it's hicas-less...

It's lighting up to tell you there's an error with HICAS... namely there's two metal collars stopping it from moving.

cheers cul, i wasn't sure how it worked, thought it might give it a mind of its own eg. changing lanes at high speeds make u die. but that sounds ok, so i'll proly keep it there
