We recommend 10mm Front and 15mm Rear for a perfect flush look, Why 10mm and not 7mm?

Coverage and how to read this overview

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.

POST 1 / ORIGINAL POSTEROriginal post

I have a 2004 C4S with 18� GT3 wheels. Trying to figure out what wheel spacers to get to make them flush. Have read 7mm up front and 15mm in the back. Any advice? Appreciate any help!

POST 2Original post

That set up is exactly what I had on my Turbo for awhile. It was perfect without any rubbing of wheel wells or liners.

POST 3Original post

I have 15 and 7 and I think my fronts could use a few more mm. The back looks good though. It’s on a narrow body though so I’m sure there is some difference.

POST 4Original post

The original 5mm porsches ones i used were great

POST 5Original post

Well, it's tough to say unless you tell us offset of your wheels. It's not clear to me if the wheels you have o are GT3 wheels or GT2 wheels. The wheels look the same but offset is different by like 18mm if I recall. For OEM C4S turbo twist wheels, my son uses 7mm in the front 5mm in the back

POST 6Original post

I have 10 front, 15 back on twists with no issues. 7MM is too small for the front IMO and they do not have a hubcentric lip, banking on there being enough lip left over on the hub to make them hub centric. If you don't fit your wheel on perfectly you may have some vibration. Since your car is not lowered you could even go 15 on front and be fine.

POST 7Original post

Like LowPue says, doesn't matter what spacers you have unless you know what the wheel offset is....

Great point. I'll have the shop help with this next time I bring it. Cheers!

POST 9Original post

Offsets are on the wheel right next to the valve stem if these are OEM Porsche wheels.

Just looked... Front: 18x8x50 Rear: 18x11x45 Does that help? They�re OEM wheels

POST 11Original post

This is really easy, it�s what I did on my 2002 C4S when I got new wheels and tires. Just bolt them on the car, look at them, and decide how much more you would like them moved out. That is the size spacers to order.

Hey Sean, We recommend 10mm Front and 15mm Rear for a perfect flush look, Why 10mm and not 7mm? Because the 7mm spacer does not come "Hub-Centric" and may cause vibration at higher speeds, so why not avoid that issue and go with the 10mm! the added 3mm wont cause any issues or rubbing and will actually look nicer. Hub-Centric means that the spacers has an integrated hub center ring that will properly center your wheel to eliminate any vibration.
