Hicas lock is very effective for track work. The hicas system is actually not to bad for road driving, but it corrects you, so if you're drifting, or taking a hard corner, it corrects your over/under steer (This is my understanding). I got intoa bit of trouble one day cuase the hicas kicked in when i was going sideways, and it nearly cost me my car. I know for a fact, that any car that is set up for track (skylines that is) they use the hicas lock system by religoin. If you're going for track use hicas lock. Its $295 for the TOMEI hicas lock, which is the best one out as far as i know, its availabe at nismo.com.au

If you want to turn of the HICAS, and can put up with the light, you can just pull the sensor connection in the engine bay. It will allow no signal to got the HICAS computer. I put in the tomei kit,and it tells you to do this. The interceptor that plugs in to the HICAS computer is just ot stop the light coming on.

i'll scan the instructions tonight and post them

I'm not 100% sure but I think there is more to it than that.

The Tomei HICAS lock (I've got one, he he he) has brass shimms that need to be installed in the hicas system somewhere. You can see them in the picture above.

Now I honestly have no idea where or why they put them in, but I'm sure it's for a reason.

I've never driven a R33 with HICAS hard, so i can't compare, but I know mine is very predictable when sideways :D

I don't know if the r32's are the same....but a very quick and cheap way is to dissconnect the HICAS plug at the diff.

You will get the dash board warning light thou...

takes about 30 seconds. this was on a r33

The brass rings in the Tomei kit are to mechanically lock out the HICAS actuating rods located next to the diff.

I haven't put these in yet, but have done the rest of the installation. Main reason being is that you need to get your wheels re-aligned because it gives each wheel more toe in, and I have only just got them alligned.

It seems funny that you cannot just buy an electronic device to disable the HICAS....perhaps it really isn't that safe to ONLY electronically disable it? I have felt a HICAS "Twitch" and at highway speed or more I wouldn't want that to happen.

This is why all the HICAS lock kits by TOMEI, CUSCO etc are both mechanical and electrical.

Chris32....lets say that the brass rings are 3mm thick then all you have to do is wind the tierod end IN 3mm to compensate for the spacer. Shouldn't be that hard.

      A locally delivered Infiniti have remote start installed but don't come with the remote start key. You need a new remote start key and they just need it programed. And this is different to making/programing a new key that just starts the car.

      Cheers, and cheers for sharing so much of the build and also sharing the glimpse of what turns out to bring a lot of us poor decision makers together haha.  I do recommend learning more about how to manage it, if not considering getting a  formal diagnosis.  The discussion with the psychiatrist I got my diagnosis through was quite eye opening, things I'd not even considered to be ADHD related and hadn't mentioned were things she asked about out of the blue and were common themes with people with my flavour of ADHD.   It's not a label for people who are hyperactive and ill-attentive, there's more to it than that and some of it can be much more challenging or damaging - though there are of course two sides to the thing, and a lot of the stuff we have to go through and work on to live with it make us effectively "better" at other things as well. Aside from the fact that there is some argument I could have a bit of ASD seasoning in there (came up during the diagnosis, and neurodiverse things seem to not stay as a cookie cut) I suspect you need to learn more about ADHD if you are puzzled about how hyperfocus could possibly apply.  I *do* personally use "superpower" with quotes deliberately, but it's 100% an ADHD thing due to the exact reason that lack of focus is also an ADHD thing... Loosely speaking the inattentive side of ADHD isn't the inability to focus, it's the inability to control where the focus goes.  Not being able to sleep because brain is more interested in thinking about a stupid thing I said to a girl I liked 30 years ago, not being able to focus on work because my brain is more keen on putting together the torque management strategy we're going to try out with a drag car next weekend, not being able to focus on a conversation with someone I WANT to listen to and respect because there is a flickering light in my peripheral vision.    If I could just stop work and build the torque management setup right there and then I'd not hear anything else until it was done.

      Maybe you should do some more reading.  Google positive effects of ADHD and you'll get your answers.  One of my personal downsides of ADHD has been talking before I think.   Maybe you have it too?

      Excuse me for butting in....but which part of ADHD can be considered a superpower? I would have though it far more likely that some ASD comorbidity is more likely to be contributing to an ability to hyperfocus on something. ADHD being aimed somewhat in the other direction. My shed looks like your shed. My whiteboard list of unfinished projects has entries going back 15 years. I know what you're talking about - I just struggle to connect ADHD to the results being discussed.

      Thanks for reaching out!  It's a blessing and a curse at the same time.  I'm undiagnosed but it doesn't take a rocket scientist to see it in me... I have more half started projects laying around my house, shed, garden, etc taking up space and money, destroying aesthetics than if I added up all of my mates projects together. But, ADHD gives me the ability to hyper focus on things that no mere mortal could even  comprehend.  A recent pool build is an example of that....  I dont know anyone else that would be dumb enough and focused enough to take on then complete something of that magnitude. I call ADHD a superpower but it can equally be completely destructive if not controlled and focusedon the right places. Addiction is a major concern to ADHD people and thankfully my addictions have been no worse than projects, XBOX, chocolate and being an arsehole! It's often hereditary and my 13 year old son is currently learning how to drive it at the moment. Keep lurking! If i can finally finish this bloody thing at some point it will be a win for all of us ADHD'ers! 🤪
