School me on extended lugs for my Skyline. The fronts are easy to come by, but I am hearing mixed things about the rears. Can you guys confirm or deny:

- The rear studs are a different spline than the fronts.

- My car shares studs with the 300zx.

- What is the stock lug shank length?

- How thick of a spacer can I safely run with the stock lugs?

I am working on fun summer wheel options and the wheels I am keen on will require a 10-12mm spacer.

Any help is appreciated, thanks all.

Whether or not you need extended studs will depend on your wheel type. My Stagea has different front and rear splines.If you are using aftermarket wheels you may need hub centric adapters as well. When buying studs (if required) the advertiser should be able to tell you what they fit. 10mm spacers should be  hub centric like this (you will also find extended studs on this site):

4/5x114.3 10mm hub centric slip on spacers

I'm looking at BBS LMs currently. I have the hub-centric stuff handled (I work in the VW world and we deal with that as well). So far, the stud sellers are able to indicate how much longer than stock (i.e.- 10mm, 20mm, etc).

and, if you look at the site I sent you, the diameter. If you don't know what size your studs are email GK Tech and ask. On my Stagea the rears are bigger than the fronts.

Just looked over their site, they have a handy chart in each lug listing and have options for the front and the rear. Thank you for that link!

    • Hi all, Restoring r33 series 1 rb25det. All the heater hoses were on their way out, have replaced them and put it all back together. After testing I noticed a small leak from behind the head on the actual metal water line to the turbo when cars warm. I tried running a longer hose over it but it kept leaking...   I am about to take the (stock) manifold off again😔 to change the water line does any one have any lines they recommend? I was looking at Aeroflow Turbo Oil & Water Line Set but not sure what everyone else recommends. Car is completely stock but want to upgrade turbo eventually. it looks like ill have to disconnect a lot just to replace these lines so if there's anything else recommended to do please let me know. Thank you in advance!
    • From memory, on the R33 GTSt at least, while everyone says "It's not adjustable", I found when I changed clutches in mine, it just needed a small adjustment on the rod length. But be very wary here, as you could end up trying to push the pushrod in the master too far, or blowing out the slave.   Most likely though, if the master/slave isn't bypassing internally or leaking out, then the throw out is the wrong height compared to the fingers on the clutch, so when it moves to disengage the clutch, it isn't 100% disengaged. You can check part of this out too by jacking the car up, having the engine running, put your foot on the clutch and try to engage 1st gear. If it goes in pretty easy (Compared to the ground) and/or the wheels start turning a fair bit and it takes a bit too much brake pedal to bring them back to a stop, this is likely the issue.  I'm not sure if you can adjust the height of the forks etc in these though, it's been that long since I've touched any RB gearbox.
    • That's all good, I thought I was missing some interesting feature! Maybe @PranK can double check if that is something that is meant to be operating or not.
    • I hope that is not something that bad. From what i remember he said that only first gear is "hard" to get in and that he has couple of ideas what to try next but idk 😕  hope it is not gearbox out. I will let you know.
    • If it's not the hydraulics, it is probably gearbox back out. Usually as per @Duncan's post, or otherwise associated with not getting the throwout fork positioned correctly. All the way up to catastrophically bolting shit back together without it being aligned properly and wrecking the clutch/input shaft/flywheel/something else.
