    I'm looking to install 10mm wheel spacer / adapters and want to install extended wheel studs. From my research it looks like the factor wheel studs are as follows:
    M12-1.50 Serrated Wheel Stud - 14.20mm Knurl 40mm
    So my guess would be at I need 10mm longer studs.
    M12-1.50 Serrated Wheel Stud - 14.20mm Knurl 50mm

    Would these linked below work? Or are my wheel studs dimensions wrong?

    Are your spacers going to be hubcentric as well? Because if they are not, the studs will be supporting the weight of the car, not the hubs. At the minimum, get some hubcentric rings.

    This is not quite true... the hub centric hub centers the wheel by the lip in order to install the wheel properly to avoid inbalanced operation and vibrations...
    The weight is suported by the static friction between the hub and the wheel... So the screws or studs in either case provide the tention to keep the 2 faces pressed against each other... maybe they could support the weight if the wheel gets loose like a hubcentric lip would... But they would deform and snap... Because either way that is not what they are made to do...


    As regards the length of the studs... I can confirm too that they are 40mm on the 3rd gen hubs... In my case I wanted to add aftermarket rims so I needed 15 to 20mm longer studs in order to achieve it...
