I think my car used to be one of those sunday cup cars in japan. It had HICAS removed, no A/C compressor, wires in the dash for a helmet or something and it had no spoiler when I bought it but the boot has holes filled up where the GT wing used to be. Oh and the F50 brakes had massive heat glazing and cracks on them. Guessing it copped some serious track time....

Looks like a waste of weight to me then. Glad I dont have it anymore. I'd rather not have the bum wiggle around like a brazilian dancer.....

afaik it was a hydraulic system in the r32s. so a fair bit of weight to be gained by removing. r33s have an electronic system. whish is hooked up to the power steering somehow. possibly why the car feels heavier for some. check you pwrsteering.

btw, Wee Free Men FTW!!!

Wow, lots of different opinions here on HICAS.

Does anyone like me feel they should leave it in because its kind of a skyline trademark or feature which Nissan designed into the vehicle?

I mean, I cant say I notice it that much at all anyway. I like to think thats how it should be, you know doing it's thing without you really noticing it too

much.

Having said that, I'd rip it out in a second if it gives me trouble, and requires a lot of cash to repair it. That many people seem to think its better without

it, and my GTR's no feather-weight machine, so it could do with a diet.....

Staying put for now.

Anyone know how much it'd cost to get it taken out and have a lock bar put in (for future reference) ???

I do feel a bit this way. I mean Nissan obviously thought it was a good thing at the time... I guess for me it's a case of if it aint broke, don't fix!

I do notice it a little bit... the first time it kicked in it was a bit unnerving, but when you expect it it's quite good. I guess it comes down to what you use the car for. For drifting it's obviously not a good thing, as you certainly don't want the back end flopping around when it's sideways, but for mid-high speed cornering it's actually quite good. In theory it should help with reducing body roll and increasing stability, as well as allowing for tighter cornering at mid-speeds. I'd really love to know what speeds the stages kick in at though! I often feel it if I'm takign a roundabout quite quickly, it really feels like the back end is hanging out... but without breaking traction, and then it really pulls in nicely. At quite high speeds (i.e. over 90km/h) it feels slightly weird as it kinda crab-walks across the road if you turn only a tiny bit (if you barely move the wheel it kinda moves across without turning...).

my major concern was when going sideways (legally of course) having it turn on and off as you go over the thresholds

The 4WS system on the Honda's is designed as a parking aide, as it actually works in the direct oppposite way to that of a 'line. Ours turns the rear wheels THE SAME WAY as the front wheels... the hondas turn the opposite (tighter turning circle). With ours the car kinda 'side-steps' across the road slightly rather than having to turn and lean the car over.

Yep, the Prelude system was quite different.

I had an '88 Lude and at first, I had to be extra careful when reversing because it behaves rather differently. But you soon adapt to it :banana:

To this day, I havent been in a car that cornered like that thing did (aftermarket suspension natch) - just amazing - despite the front wheel drive.

And you sat so low to the ground, which no doubt partly explains the cornering ability.

Yeah a mate's got (kinda... it's been sitting unregistered on his front lawn for a while now...) an '88 prelude... it's really quite novel to drive! It's got a turning-circle that absolutely kicks ass! He's got a really small court out the front of his place... in the line I need to either make it a 3 point turn or give it some revs and some clutch dump ;) to flick the back around... he can just turn the wheel and not even get too near the gutter!

And damn... you do sit down low in that thing! Pitty it doesn't have any power :teehee:

Been to the track in both HICAS and non HICAS skylines and I can honestly say that HICAS helps quite a bit in the corners allowing you to turn in just a bit more then the non hicas car.

Anything under 30km/h HICAS does NOTHING, anything up to 80km/h turns the wheels the opposite way as the fronts allowing tighter cornering (calculates how much angle depending on steering wheel position and speed) after 80km/h it will turn the wheels the same way creating a dog leg effect that will give you more high speed stability.

As long as you don't plan on drifting then HICAS is great.

Pardon my ignorance. New to the skyline scene. Whats involved in removing hicas? is it possible just to turn it off to see how the car handles without? and reconnect it if your dont like it? Or doesnt it work like that.

EDIT- dw i searched :cheers:
