I've fitted some 9mm spacers to my front wheels and am getting some wheel wobble

I've removed and refitted them a few times, and have used the peg/tool thing to make sure they're fitted correctly

The spacers are completely flat, and don't have a hubcentric lip on them like the other spacers that I own

The wheels do still sit on the lip on the hubs/discs, but only just

I'm wondering, are 9mm spacers without a lip on them too much?

Do they need a lip on them to ensure the wheels are correctly centred and to avoid wobble, or is there something else which could be at fault?

 

Yes, I would suggest using hubcentric spacers.

 

that is the most dangerous scenario i have heard of, without an accident having occured.
REMOVE THEM IMMEDIATELY !!!!!!!!!!!

the hub is where the stress of the weight goes, NOT the bolts.

 

Still very new to Porsche but typically with small spacers without lip, you should use hub extenders. I know H&R makes them for BMW.

This is indeed very dangerous! I know cases where people snapped off the bolts!

 

Spacers removed!
Thanks guys!!! - its appreciated

Just to be clear, it's the feedback/shaking through the steering wheel that I'm talking about

The other spacers I have are 15mm cargraphic
They have a hub centric lip on them, but they're too wide for my current set up

I've seen quite a few spacers available without a hub centric lip - Are any of them ever worth considering?

ie; it sounds like the 9mm ones I've got are too wide to use without a hub centric lip, but what about a 6mm spacer?

Would a 6mm spacer be thin enough for the wheels to still sit on the hub, or are they always a no-go?

Thanks

 

Measuring the hub should give you the answer but I personally would never use small spacers without hub extenders. I'm sure someone makes them for Porsche. This is what they look like for BMW; snaps right on the hub.

My car came with the RUF 7mm spacers which are the only thin spacers made that have the hubcentric lip on them. They are pricey at around $200 for the pair but well worth it. The RUF part number is R96 331 611 07.

7mm non hub centric leaves enough "hub" to work great. You need hub centric spacers after 7mm. Make sure you use the correct bolts!

Non hub centric


Hub Centric:

 

What Turbo Fanatic said! Were you using longer bolts???

 

Spacers are never a good idea.

 

^agreed !!!

 

That's why Porsche puts them on several cars as standard equipment at the factory like the GT3 for example.

If done properly there is absolutely no issue with them.

 

would have to agree with that...

 

are you sure the gt3 has spacers as standard ?
i know that 911s and turbos are offered with 5mm spacers, but i didnt hear about this on gt3's/2's...
can you confirm this 100%

 

woops

here's a mini gt3 at the burgeer king 500
(i cant confirm nor deny this is spacer related, but it popped up when you type wheel spacer fail)
