Longer wheel studs vs spacers
 

$7 for 10 studs (+ making the spacers) or $210 for 2 bolt on spacers

Can you get studs cheaper? (72mm)

Opinions?

How long/deep are the spacers you're using?

From a conversation with an old school race engineer from a few years ago, I am of the understanding that anything up to 10mm is fine as a hub-centric spacer.

i need 30mm for the rear and have forgotten the front. so 72mm studs would be required for the rear alone.

I don't have any qualifications in the area, nor have I studied the information I was given.
However - I was advised by a source that I trust to avoid using spacers longer than about 10mm when possible.

I trust using spacers, I'm not sure about your 944, but my turbo has factory spacers on the front, also the 930 (i believe) has 27mm spacers factory.

I will be using hub-centric spacers, either with longer wheel studs or bolt on spacers (what the 944 has)

I'm just tossing up between the 2 options.

We went with longer studs up front on my S2 to get the 996 wheels mounted with a 7mm spacer. Its the way to do it, i trust it way more than a bolt on spacer deal. Steel lugnuts are also good idea.

Run a high quality hub-centric spacer and the proper length lug bolts and you will be fine. I'm not a fan of anything above 10mm as it adds a much increased element of weakness to the hub, a wide spacer and longer studs is never going to be as strong as a correct offset wheel on stock studs, but then again I've known people who run with wide spacers without issue.

If the spacing required is more than 10mm, like 25mm, use a bolt-on spacer with its own studs. If the spacing required is low, like 5mm, use a slide-on spacer with longer studs, because there's no bolt-on spacer that thin.

Pros of bolt-on spacers: waaay easier, change/remove at will.
Cons: heavier, minimum thickness.

Keep in mind, if you use very long studs, when you try to run without spacers they will poke out :(.

Should have added, I need 30mm (roughly that size) spacers, Thats why i said 72mm studs

Agree with most of what's been said here. However re: "Can you get studs cheaper?"
Please don't go cheap here. You get what you pay for. And if you are going with a wide spacer you really don't want to combine that with "cheap".

And if you are going to ever track the car... keep the spacer width under 20mm. Preferably under 10mm on the "heavy" end.

The brand name is O.E.M. but that doesn't mean it's the original equipment manufacturer. I'd call Sunset and ask for a price on the studs.

They are around the same price, I ordered some not too long ago

Guys remember, i'm in Australia. I cannot just call a US store :thumbup:

damn Australians :P
