Wheel stud length? I am confused as to what is the factory stud length. I seem to be finding conflicting info on the internet. I thought the studs were 45mm . I am installing 10 mm spacers Eric Shea recommended 56mm which would make sense for 8 or 10mm spacers if they are 45mm. Then I found this add on Paragon.



Replace those tired and damaged wheel studs with our new pieces or increase the length for use with spacers.

Here's a basic list of sizes used as original:

45mm - 944 83-86, 924S (front); 924S, 944 85.5-89, 944S, 944S2, 944 Turbo, 968 (rear)
50mm - 944 85.5-89, 944S, 944S2, 944 Turbo, 968 (front)
52mm - 911 65-89 (front and rear)
66mm - 911 Turbo 76-89 (front)
66mm - 944 83-85.1 (rear w/factory spacer)
72mm - 911 Turbo 76-89 (rear)

A 914-6 isn't listed but I would think it should be the same as a 911 So now I am confused. Anyone know for certain what is the original stud length on a 914-6?

Thanks

Tom

I thought they were the same as the 911 (50-52mm)

I put 72mm on the front and 100mm on my car and use open lugnuts

45mm

As personally measured moments ago using an original /6 hub...

Thanks guys.

I had the 45mm in my head and was just shopping for the right length until I saw the Paragon listing. I think they just have it wrong. I want to stick with the finished look of the alloy lugs so I need to get this right.

Thanks again

Tom

I believe they have the descriptions mixed up:

45mm - 911 65-89 (front and rear)
50mm - 944 83-86, 924S (front); 924S, 944 85.5-89, 944S, 944S2, 944 Turbo, 968 (rear)
52mm - 944 85.5-89, 944S, 944S2, 944 Turbo, 968 (front)
66mm - 911 Turbo 76-89 (front)
66mm - 944 83-85.1 (rear w/factory spacer)
72mm - 911 Turbo 76-89 (rear)

Tom, figure your spacers and, you have roughly 5mm to play with under those aluminum nuts.

What I determined is that 356 uses the same basic stud as a 911 or 914-6. Automotion has a 56mm stud listed as a 356 part that should be great with either the 8 or 10 mm spacers.

Tom

Yup... pretty simple. Just add your spacer width to the stock stud. 45+10 = 56mm

I'sat Utah math there Big Love? You came up with an extra (in this case) mm...

Gots to. Go-a-search'n for 55's

(extra's gud)
