Just a quick question, I have fitted some 10mm spacers to the front of my 996, now these spacers are flat, no lip, when I put the wheel up to the hub now I have lost the lip on my original hub, so my question is do I need the a lip or will the five bolts suffice, it’s seems fine just thought I’d check first, I have used 37mm bolts to cover the spacer and get 8 plus turns on the bolts when tightening!

properly installed wheel spacers are perfectly safe

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Hi everybody, hope your all having a lovely weekend!
Just a quick question, I have fitted some 10mm spacers to the front of my 996, now these spacers are flat, no lip, when I put the wheel up to the hub now I have lost the lip on my original hub, so my question is do I need the a lip or will the five bolts suffice, it’s seems fine just thought I’d check first, I have used 37mm bolts to cover the spacer and get 8 plus turns on the bolts when tightening! Also the spacers are 5x130 with no tolerance, 5 holes fit like a glove!
Is the weight of the car on the Lip or the Bolts or is the lip just to centre the wheel, my spacers are fine if the latter is the case.
Cheers

Are wheel spacers safe?
Yes.
When properly installed they are just as
safe
as wheels installed without spacers.
Will wheel spacers cause my wheel studs to bend?
No.
The load from a wheel is transferred to the axle/hub through the
friction
of the clamped joint, not through the wheel stud. A wheel stud can only bend if the lug nuts are not properly torqued, in which case the wheel is about to fall off, anyway.
The Physics of Keeping the Wheels On
As long as the wheel, hub, and spacer are
stiff enough to prevent flexing
and loss of clamp force, the
cause of most wheel stud failures is under tightened
lug nuts (not enough clamping force) or
over tightened
lug nuts (the stud has been stretched past it's elastic limit, so the clamping force goes away). Therefore,
properly installed wheel spacers are perfectly safe
.
The wheel stud applies a
clamping force
that holds the wheel to the hub. When the lug nuts are tightened, the wheel studs
stretch elastically
, like very stiff springs. The lug nuts should be tightened until the stud is at 90% of its
elastic limit
. This will provide the
greatest possible force
to hold the wheel to the hub.
The amount of
clamping force
at a joint is important because of the coefficient of friction (Cf). The more clamping force applied to the joint (in this case the joint between the wheel and the hub), the more force required to make the wheel slip relative to the hub.
Unless the wheel slips
on the hub, there
cannot be any bending load
on the stud.
Coefficient of friction
-- There is
friction
between the wheel face and hub face. This friction can be measured, and it is called the "coefficient of friction". The coefficient of friction (Cf) is the ratio of normal force, at the intersection of two surfaces, to the lateral force required to slip the bodies relative to one another. As an
example
, good street tires have a Cf of 0.9. This means that if there is a 100-pound vertical force applied to the tire, the tire can generate 90 lbs. of cornering force before it slides.
When the car starts moving, the
stress applied to the stud does not change
appreciably, unless one of two things happens:
The vertical component of any external force applied to the wheel is so great that the
clamping force
is
not sufficient
to hold the wheel in place, and it slips on the hub. At this point the stud is loaded in bending and in shear, and may yield, or even break.
Some portion of the clamped joint, wheel, or hub is
not stiff
enough to prevent flexing, and allows the tension load on the stud to drop to zero. With no tension load on the stud, the clamped joint is no longer tight. The wheel can then move relative to the hub, and place a bending load on the studs.
[*]
Inserting a wheel spacer
between the hub and wheel
changes nothing about these physics
.[*]The hub center of
a hubcentric spacer does not hold the spacer on the hub or reduce the chance of stud failure
. There is
never any load
on the lip of the wheel spacer. For there to be a load on the lip, the friction force in the joint must have been completely overcome. The lip on a hubcentric wheel spacer serves only as an aid for wheel installation.[*]
Increasing the length
of the wheel studs to use a wider wheel spacer has no appreciable effect.[/LIST]
