Just bought a 2006 Carrera S coupe. The wheels are the "lobster" style.

Just beginning research on spacers when I noticed my right rear wheel is pushed out flush to the body whereas the other three are slightly set inside. Camber looks fine at all four corners. I suspect the one wheel was replaced with the wrong offset, curb rash fix perhaps?

What's the "normal" offset specs for factory wheels for this model and style, front and rear?

 

You will find offsets of your OEM rims stamped on the wheel itself - actually it is not stamped as an inset stamp - rather the numbers are raised.

 

Thanks, that was easy! Found it stamped by the valve stem. I'd half expected it stamped on the back of the wheel like other cars I own.

Sure enough the rear left is a different offset than rear right. Here's the specs, all 19 diameters:

Front Left: 8 wide 57 offset
Front Right: 8 wide 57 offset
Rear Left: 11 wide 51 offset <-- 4S offsets
Rear Right: 11 wide 67 offset

Page 288 and 289 in the owner's manual has the official size/offset combos for C2 and C4.

 

Since semicycler's left rear wheel will be stamped with one offset, and his right rear wheel will be stamped with a different offset, which wheel should he replace?

My '08 C2S 19" Sport Design wheels are stamped as follows:
FRONT: 8 x 57
REAR: 11 x 67

Hope this helps, but I don't know if the specs for '06 lobster-forks are different.

 

Yep, wide body offset. If you need a lobster in narrow body let me know.

 

Well since I need to swap one rear wheel, I can swap the rouge wide body for a narrow body, going back to stock and then add spacers for a more aggressive look.

Or, swap the narrow body one for another wide body giving the flush look on my C2S without spacers. Make sense?

To be honest I'll likely swap the one with more cosmetic damage and then deal with getting the flush look just right with spacers separately.

 

so the et51 is flush and not outside the body? sounds like you save having to buy spacers with this one... i am considering doing this rather than adding spacers

 

I think I'd ask the seller to provide the correct wheel.

 

[CORRECTED]

Yes - the Rear right C4S wheel with the 51mm offset is flush on my C2S car, or barely outside the top of the wheel well by less than 2mm. It's the same look the C2S left wheel 51mm offset with a 16mm spacer would have.

[/CORRECTED]


What's a popular spacer size for the narrow body rear? 10mm? 15mm?

 

???? i thought that a 67 ET with a 15mm spacer would bring the wheel OUT 15mm towards being flush with the wheel well

 

You're correct - a wheel with a 67mm ET + 15mm spacer is equivalent to a wheel with a 52mm ET. I'm not understanding why the OP just doesn't get the correct wheel - it's a high performance car - why run one rear wheel with a 51mm offset and the other rear wheel corrected to almost 51mm offset using a spacer - come on man.

 

[CORRECTED]

You are both correct. My original comment here had it backwards.

[/CORRECTED]

I'm also not putting spacers on one side, that's silly. I'll match the wheels swapping one to make a pair and then adjust offsets as needed with spacers as a pair. Which wheel goes and which stays is the discussion.

As OP, I compeletely agree and am doing just that. Step one match left and right. Step two adjust offset to get the aggressive look to my taste. If I can achive both without spacers then even better.

Wheel condition matters too. Why would I keep a curbed wheel when matching left to right? This particular vehicle is not in mint condition. But it has not been abused either. There is minor curb rash to deal with, nothing obvious, but its there.

 

[CORRECTED]

Yes. A C4S rear wheel on a C2S car is flush. The same effect can be had with stock C2S rear wheel on a C2S car with a 14-16mm spacer.

[/CORRECTED]

 

I run wheels with widebody offsets on my car, based on a recommendation from Jason, a fellow 6-speeder. They're flush, with no spacers. I'm very pleased with them...

 

11 ET52 wheels are perfect for narrow bodies !
