  • four lug to five lug conversion help needed 85NA

    I've been work on this project to put my set of 1987 5-lug turbo wheels on my 1985NA 4 lug car ...

    I bought a set to 4-5 hubcentric adapters ...

    Problems in getting there are

    1 ( one lug has to be replaced with a long replacement adapter lug ... ( so it looks like I need to pull hubs to replace the lug ...

    Is it possible to replace lugs without removing ?

    2 offset seems to be too much ...

    Has anyone done this before ? ( I sure someone has )

    Here are some pics :

    Sort of answering my own question : So he cuts an access hole on the rotor dust shield ... seems to answer the problem ...
    Z31 Extended Wheel Studs

    Published on Jun 29, 2018
    The time has finally come for me to get around to doing this job. The stock wheel studs on my 85 Z are barely long enough to hold a wheel on, so today we are upgrading to Nismo 60mm studs front and rear with new Muteki SR48 lugs!

      I always wanted to do that, wish I had seen your method of using a spacer approach before I bought my new wheels, oh well. Good luck with the final approach!

          Those are great tires for sure, I ran those on my Q45 and they are excellent tires, you will love them. I ran RE71 Bridgestone also picked up on sale, I only trust Briidgestone and Michelin, everything else is an inferior choice.

            Well It took some time but my 87 wheels have been refinished ... and I have the new tires mounted ... I ended up with Mich pilot AS4's ,,,

            anyway the test fitting looks good ,,, I have a set of new Eibach lowering springs that I'm going to install and with a 1-2 inch drop It will look pretty good ...

            Several issues mainly the 60mm stud that has to go in ... I'm doing brake pads and rotors in the process of this . So removing the hub is part of the process
            Also in case I need to put the stock 85 wheels back on after all this is done will require one open lug on each wheel that fits on the old wheels .

            The fronts should be no problem , I need to cut the access hole on the back dust shields to do the stud there Oh what fun ...

              The extended studs supplied with the kit had a non fluted stud ,,, So I'm ordering 60mm extend stud from here : 40 bucks more money ... ( I only need 4 but have to buy 10 ...)


              60mm Extended Wheel Studs [12.9-13mm knurl]


              Direct replacement for all Nissan/Infiniti wheel studs. Made from high strength cromoly, zinc plated for corrosion resistance, and tempered to be safe for use with aluminum lugnuts.

                Tough project, it will look way better with the new springs, I did that a long time ago and much prefer the stance now lowered by 1.5"
