Correct Boss Hub for R32 GTST

[Zabuza]

Hey all , I was wondering if someone could point me in the right direction in finding the correct aftermarket steering wheel hub for my car. I have a 93 (so late model) R32 GTST coupe with Hicas. I’ve already tried 2 different HKB hubs which were ON-110 and ON-115 and both are 1 notch off from top dead center so they keep throwing my Hicas light. Does anybody know which HKB hub is the right one for my specific car? Also fine with a different brand hub if anybody knows what will work, just want my wheel to be straight and my light to stay off lol

I'm confused by "one notch off from top dead centre". If you rotate it one notch is HICAS happy?

If so, I think the issue is more likely your tie rods have been set unevenly in a previous alignment, so put the boss on straight and get the alignment checked.

It won't be an issue with a nissan style boss being wrong, there are billions of cars running them with no problem

Wot he ^ sed.

Better solution....bin the HICAS altogether.

@Duncan don’t believe it’s alignment or suspension related because my oem wheel sits perfectly straight and my car doesn’t pull one way or the other and with the oem wheel Hicas is indeed happy. What I’m referring to is the hubs I have always want to slide on to the steering column splines either one notch to the left or one notch to the right instead of sliding on straight like the oem wheel. From what info I have found , it seems the early model year 32’s and the later model year’s have a different number of teeth on the spline so I believe that is the problem, I’m just not sure which hub will have the right tooth count to match my steering column.

Not possible for the spline count to be different and put the wrong one on.

Is your hub actually capturing the steering angle sensor drive tab? Not putting it on upside down or otherwise clocked wrongly?

Fair point, maybe it’s not the number of teeth that’s different but the orientation of them? I mean I’m going by the arrow labeled “top” on the hubs when I try to line it up so don’t think it could be going on upside down. I saw a chart someone made a while back that showed what different boss hubs supposedly fit all of the different 32 models and variants but I can’t find the damn thing and it was kind of confusing hence why I probably bought the wrong one. When I have it apart again I can post pictures to help explain.

Ok after looking at DriftWorks site it appears the ON-110 I tired is for an earlier model year and the ON-115 they have labeled as GTR specific, so I’m going to give ON-112 a try as the description they give says it’s for late model skylines with Hicas. Fingers crossed , had no clue so many different variants of hub existed.

For anybody finding this in the future here’s a fantastic chart that shows which HKB Boss Kit goes to just about any Nissan you may have
