Hey guys,

Had a question RE HICAS, noticed this while driving, after i hit 80KMH + my steering starts turning to the left slowly until i hit about 100KMH but my car is still going straight (pic 1).

If i slow down to under 80KMH or HICAS light turns on my steering returns back to normal (pic 2).

weird...

time to remove HICAS?

I'm willing to bet that that steering wheel you have on there does not have a HICAS suitable hub. There is a steering angle sensor in the top of the column that gets driven by a pin on the back of the standard hub. With no drive pin, the HICAS computer gets no steering angle input and eventually goes out on fault. One of the behaviours it likes to do it to crank the steering wheel over to the left like that (what is actually happening is it is setting a rear steer angle that drives the car to the right and you have to wind on left lock to counteract it).

You have two choices. 1) Get a HICAS compatible hub for the wheel. 2) De-activate HICAS.

The easy way to do 2) is to disconnect the smaller of the two wiring connectors on the back of the HICAS computer under the parcel shelf. Doing so will kill HICAS, lock the rear steering and not put the HICAS light up on the dash. Win.

Ultimately, the better way it to completely get rid of HICAS with a lock bar and even better is to pull all the crap out, including the lines and solenoids and so on.

I don't think anyone has ever had any HICAS related problems before. Will be watching this with interest.

Is that sarcasm? :S

Yeah as GTSBoy said, alot of issues occur because of incorrect steering boss kit or boss kit fitted wrong. I had the second issue with mine when I got mine. I put it on with the wrong section engaging the HICAS Prong so the boss kit had about 2 or so degrees of play before it actually engaged the HICAS hub. So car still felt the same, but as soon as I hit 80km/h, HICAS light came on. Didnt really notice any issues with the cars steering etc but mine is a 33 with the Electric HICAS so it works a bit different.

Check you dont have the same issue as I had, otherwise it might just be easy to pull the whole thing out as said. I havent looked back since removing mine.

      I am yet to see anyone ever regret a quaife or helical. ...other than drifting/skidpan duties. I kind of want to upgrade my factory helical with a Quaife (but really it's not ultimately that different, and is a MASSIVE UNDERTAKING), that's how good the hype is about them, that I want to try them 'just to see'

      D2 and Ksport are essentially the same thing and basically just generic Taiwanese manufacture. Better than ChinaBay crap, but... not top shelf. Öhlins have got to be some of the best dampers around, so likely to be a good option. It's going to get to the point though where I suggest you buy from Oz. We have at least 2x excellent options here. If I were you though, I'd be talking to KW about doing something for the R33. There's bugger all difference between that and the 32. In GTR land, anyway.

      KW only offers a set for the R32 GTR. Popular options are D2 racing, Ksport or Öhlins. I have a D2 Racing coilover set, though I don't know for sure which one.

      Well, the good news is you have more than one very good option for new coilovers in and around your country. Worth the drive over to KW to talk about GTR stuff.

      Fair enough, I am in no way a tire expert so I'm not familiar with all the terms and conditions. I'll definitely note down the AD09 to potentially try in the future. Rain is not too big of a concern for now as I will probably only drive in the rain when I have to. And considering I still lack experience driving the GTR I'd more than likely take it easy too. I have coilovers in the car but as I barely got to drive so far I never bothered to even check if they are adjustable haha. The suspension is almost entirely old and worn as well so I suppose when I eventually fix that in the future that would make a huge difference.
