Today I have been mounting spacers. Impossible for me unscrew little screws on hub. I have installed spacers with no screw, but with 130Nm on longer bolts. I just hope no problem. What do you think?

The little screws are more for convenience...they hold the spacer to the rotor/hub. They keep the spacer in place when mounting the wheel and when removing the wheel. If you don't use the screws, then the spacer may stick to the back of the wheel or simply fall. If the spacer falls into the wheel, it could scratch or otherwise damage it. The lug bolts hold the wheel, spacer, and rotor firmly to the hub. --Brian

Then I can do without screw with no problem (unless removing a wheel).... thanks Qship, now I am in calm.

Do you really think Porsche publish TSB with no exhaustive checking? I really dont believe.

What you say is sense but TSB says it.

However, as we are in whole doubt, I have bought the complete kit with longer bolts. No concern money, only I am seeking for curiosity and learning.

I looked at these TSB's:

-- 4/04 4440, dated May 25, 2004, Summer Tire and Wheel Summary

-- 5/04 4440, dated Sep 14, 2004, Winter Tire, Wheel, & Snow Chain Applications

On page 7 of both TSB's, it is pretty clear: When using the 5mm spacers (no matter what wheel), you must use the +5mm GT3 bolts.

However, there is a discrepancy in the footnoting, which is apparently fouling the situation here. Note the following:

-- The summer tire TSB does not denote use of the +5mm bolt when outlining use of the spacer for the 18" wheels at the bottom of page 2 (see footnotes on page 3).

-- The winter tire TSB does denote use of the +5mm bolt for the same wheels on page 3.

Considering page 7 of both TSB's, coupled with practical logic, use +5mm bolts with 5mm spacers.

--Brian

good job!! However I still think there is no mistake in TSBs, page 7 of both TSB is for size wheels that require longer bolts.

In 18" winter tires, longer bolts are required and not in summer tires. I am not sure if I am thinking wrong but this is what TSB says!

Yes, but elsewhere in that TSB you will find:

Wheel mounting must take place with the 5 mm longer wheel bolts of the 911 GT3, Part No. 996 361 203 90 or 996361 98000. These GT3 wheel bolts are marked with GT or with a red color on the face surface (arrow) of the bolt head, or the rotating spherical cap ring is galvanized in red. Dimension X = approx. 50 mm. Tightening torque: 130 Nm (96 ftlb.).

If you use 5 mm spacer (with any wheel or tire) your existing bolts will be 5 mm too shorter. This means that there will be 5 mm less thread contact to hold the wheel on.

Porsche sells the 5 mm spacers with the longer (5 mm longer) bolts. I would not use the 5 mm spacers without the 5 mm longer bolts.

That TSB part is for size wheels that require longer bolts.

Note that correct contact to hold the wheel depends on deep throat and offset, what I mean is standard bolts can be approved to hold wheels with 5mm spacers in 225/40/18-265/35/18 but not with another.

So I understand.

Could you contrast to Porsche?

The 5mm spacers require a longer wheel bolt. The 17mm spacers have bolts to the rotor/hub and then you use your original bolts to bolt the wheels to the 17mm spacers.

Hi loren, pay attention to TSB, footnote 5 (only with connection with longer bolts..) IS NOT MARKED for

225/40/18 7,5 /50

265/35/18 9/52

only 2 (for boxster from MY98) and 3 (remove spacers when mounting spare wheel) ARE MARKED.

I am convinced longer bolt is not required for this wheel size.

5 mm front and rear

or

5 mm front and 17 mm rear (with specified tire and wheel sizes).

Well, In mycase 5mm f/r only approved, but I have question about bolts.

I understand there is no necessary to replace standard bolts for longer bolts as footnote 5 is not marked. What can you tell me?

You will find approved spacers as well as wheels and tires in TSB 2/04 4440 Summer Tire and Wheel Summary -- dated May 25, 2004. As a Contributing member you can read that in the TSb section here.

Thanks Loren, Can you tell me thickness approved? I have not clear.

I want to know the spacers thickness accredited for Boxster MY99.

I know 5mm is accredited cause I have seen these spacers in tequipment kit, but 17mm (for rear) is written in Owners Manual MY00.

Do you know with accurate which spacers are accredited for a boxster MY99? (front and rear)

wheels:

front: 225/40 ZR18 7,5/50

rear: 265/35 ZR18 9/52

Best regards.

In CoochasTT Car I can not see almost difference, but in BennyCga there is a visible difference...

SURE BOTH ARE 5MM?

What is this little silver under spacers? screws? what use?

Someone can tell me why porsche sells longer bolts with 5mm spacers?

I have seen that until 7mm standard bolts are used, more than 7mm longer bolts.

only for rise price of spacers? or any reason?

I want to buy 5mm spacers with standard bolts.. any problem?

:king: :king:

You can use the H&R bolts that are 7mm longer. If I remember correctly they are the 52mm bolts. You will have to transfer the collars from your original bolts to the new bolts.

WHERE H&R bolts? I am almost sure collars cannot be removed.

PArt number of longer bolts? (red)

The locking bolt is 996 361 057 90 and I believe the regular bolt is 996 361 203 90.

ed

any set of longer bolts available?

PArt number of longer bolts? (red)

when replacing pcm navi unit, display ask for CODE NAVI, Should I introduce the same I have in my old unit? or there is to introduce a new code which is sold with navi unit?

In case not have this new code... can I call a Porsche Center?

Best regards!

996.642.122.03 EFR was used through model year 2001

996.642.122.12 EWD was used in model year 2002 (pre MOST and PCM2)

If you have an older version of PCM in your car you will need to re-program the instrument cluster to match the PCM unit or your total mileage and fuel consumption will not match the PCM unit.

I want to update to pcm 16 bits. Only necessary replacing cd reader, and update to version 5.43 with a update disc. WRONG? :(

My actual pcm is 996.642.122.00 EFR (cd reader), I have bought cd reader 996.642.122.12 EWD and I have master update disc. Any Problem?

THANKS LOREN!!!

I want to update my navigation unit (996.642.122.00 EFR) -boxster MY99-

996.642.122.03 EFR

and

996.642.122.12 EWD

Just the same part number? any difference?

I need to know ... Can I use any of them with no problem?

I have a problem I just hope you can help me.

The Navigation Unit PCM1 has a code and the PCM display has other code.

But, where is stored the code? one in the navi unit and other in display?,

or is stored in the car memory ?

I want to replace navi unit but seller has not code card, he says code is the same I have in my old navi unit. but I dont see clear because I have seen new pcm navi unit with a grey code card.
