  • 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.
