The attachment to the rack was a very tight friction fit before adding the set screws, and I did drill into the rack and steering shaft to give the set screws something to set into. Also used red locktite. It's something that you'd want to inspect when you change your oil, and probably after every couple track days.

Yeah screw that. I'd rather just spend an extra $200 (assuming Z8 one fits) and not deal with any of that.

e30 people have been using stuff like this to swap in e36 and z6 racks since the e36 was a current model and I have never heard of an issue. For an e30 you put one of those condor joint on the splines at the end of the column and one on the splines of the rack. Then join the joints with 2 shafts with a D profile nested one inside of the other. The set screw goes on the flat of the D and the nested shafts means it can somewhat telescope if necessary. Id imagine you could do the same on the e46 since its a very similar setup.

Hey guys,
I just so happened to come across this thread. Sorry in advanced as this is a bit new to me.

I'm planning on installing my 712 yellow tag steering rack during this offseason and while I'm in there, the plan is to also replace the power steering lines and the steering guibo (anything else I should do?)

Are these parts you guys discussing a part that replace the current rubber steering guibo/disc? Or something that is installed adjacent to the rubber guibo?

If my plan is to replace the steering guibo with an oem replacement, it's there a better option or there?

Car is primarily a track car.
Thanks!

That is what we're discussing. I'm trying the i8 coupler first, which should arrive tomorrow. If that doesn't fit, the Z8 is next in line. Will post more as I know it...

OK Sweet. Now that i'm on the same page and know this is something to use in place of the rubber guibo/disc, i'll stay subbed.

Thanks!

I've got visions of all that could go wrong w/this coupler, but I'm actually betting that it might be fine in reality. What I wouldn't be crazy about however, is creating another possible inspection point...I prefer the set it an forget it type of replacement/upgrade part. This may prove to be a satisfactory mod, but I think I'll keep waiting to see if any of the other solutions deliver first. Thank you for presenting another option though.

Basically this. Im 99.9% sure itd be okay in reality, but for something that provides minimal benefit with a large potential downside, Id rather not take even that 0.1% chance.
