Hicas

[Vera]

So I've heard a few things about the hicas steering on skylines, but recently im hearing that people tend to lock the rear wheel steering up after a while.

I understand the concept of how it works, but can someone tell me if its beneficial in anyway and why do people choose to get rid of it..

I searched the forum before so if this has been answered before, my mistake

When working correctly does help handling, for an average driver can be the difference between putting the car into the kerb or avoiding it. But the counter-steering effect is most noticable at the track, and for experienced track drivers this can interfere with their counter-steering. Or if you are purposely making the back end slide out, HICAS will attempt to straighten you out.

When not working correctly is actually quite dangerous, and instead of trying to fix it people just buy a lockbar to stop HICAS from being able to counter-steer.

if your just driving it around the street and not doing much mods to the car I'd say keep it if its working

I got rid of mine cause the rear end was starting to feel a bit sketchy the more I did to the car. Feels better with a lock bar in for me, but down to the driver to I guess

oh right, so it counter steers for tighter turns? how does it help out if the rear wheels start to loose grip?

Best to read this: http://books.google.com.au/books?id=uqjTj_6z6cQC&pg=PA133&lpg=PA133&dq=second-generation+HICAS&source=bl&ots=hBHyO2z7UA&sig=9uQ6fhKO2OjzZIP7MPtb3gkdEJI&hl=en&ei=S7-WTvmGNMaYiAfzqLjCBQ&sa=X&oi=book_result&ct=result&resnum=3&ved=0CDoQ6AEwAg#v=onepage&q=second-generation%20HICAS&f=false

R32, R33 and R34 each have different HICAS system, which all behave differently.. Since you list R33 in profile, you would want to read the third-generation HICAS aka Super HICAS.
