    A lot of people are reading that the SS hub size is 67.1 from the forum.

    I wanted to correct this in a easy to find thread:

    This is a vid I made from a 67.1 ring on the bare front hub of my SS. As you can see, there is a LOT of free play:



    By my measurement, the front hubs are a hair smaller than the rear, front being a bit over 65.9 and rear being 66.1 flat:

    These Re the rings I am using all around, it fits very snug on the rear hub, still a hair of play on the fronts:

    These are all the 67.1 rings I got thinking hubs where 67.1 and trying different models to get rid of wheel vibration...

    Just FYI

    Interesting to know, but how odd since the front and the rear use the same brake rotor

    Great thread @iNewton and very needed as a lot of owners are changing wheels/tires

    Stock for simple clarification:

    Rear offset =. +45
    Front offset=. +42
    Bolt pattern=. 5 x 114.3
    Hub size=. 66.1 mm

    SL diameter front=. 18". Tire size= 225/45/R18
    SL diameter rear=. 20". Tire size= 255/35/R20

    Base diameter rear= 18". Tire size=. 265/35/R18
    Base diameter front= 17". Tire size=. 205/50/R17



    A link to a good chart to see what wheel/tire combos will work is:

    Your welcome!

    If anyone is considering new wheels/tires I would strongly suggest bookmarking this thread to save time in the future as hours and hours are spent on this type of selection!

    I saved all the data to a Word document and filed it in my Slingshot file folder.
    Links to websites will work in a word file.

    The hubcentric rings are helpful if you use:

    1: wheel bolts (MB, VW, BMW etc)

    2: have small face area lug nuts (tuner lugs or non shouldered lugs)

    3: a wheel that was single weight balanced

    Beyond those minor issues I have never needed them, even on tracked vehicles. They are nice insurance though if you have others mounting your wheels. The factory base wheels don't have the correct center bore and we're great. No balance issues or vibrations.

    A correction: the bolt pattern is 5 x 114.3 not 144.3

    If you made the mistake, it is worth noting that you don't need to panic.

    I made the same mistake way back in the day and I have zero issues with vibration.

    I'm not running to order the correct size and swap out the old ones. IMHO, it would only make sense if you were feeling issues.
