I looked everywhere including searching it seems no one has posted them.

The 19's for the 991 sizes are:
8.5x19 ET 54 front
11x19 ET 69 rear

8.5x20 ET 51 front
11x20 ET 70 rear


S has gotta be close to that...

Thank, haven't been on in awhile. Sold the 997 now have a E92 M3 ZCP and just love the 991s. Waiting a tad until a deal can be made, however, the choice of the current wheel selection to me is lacking.

Why would the offset be different for the 19's vs 20's considering they are the same width ... that is a little strange

Thickness of the wheel hub.

always that way, in 997 the 18/19 were different.... S models usually have lower offsets to coincide with the PASM (lower, meaning wheels sink in)

not sure where the above info is coming from but i have found pictures of the stock wheels with their oem stickers applied showing the offsets are lower than suggested above:

20" Carrera Classic Wheels Specifications:
Front Wheel: Part #: 991-362-161-30 Size: 8.5Jx 20" Offset: 51
Rear Wheel: Part #: 991-362-166-30 Size: 11.0Jx 20" Offset: 51

but this link says otherwise, not sure why the stickers would say ET51 on the wheels unless the seller has replica wheels and the stickers are reproduced and error'd

Bumping an old thread cause I couldn't find a recent one. I am looking to get down to 19" on a C2S. What is the wheel width/offset and tire sizes that I should go with?

I would be interested in this myself, and maybe a good racing tire recommendation to go with it.

This was an old thread.
A lot of good threads have emerged since.

Regarding 19", people have done 265-35-19 F / 325-30-19 R fitments.
However, it reduces tire diameter (giving unsightly wheel well gap).

I don't know what offsets people used for above [265/325 19"].
I was considering:
F 19x9.5 49mm
R 19x12 74mm

Seems nobody wants the 245-40-19/285-35-19 fitment (which better preserves diameter) and might perform great.
I thought about it, for a more comfortable street setup that might even end up performing better than the factory 20".
For that, I was considering:
F 19x9 45mm
R 19x11 60mm

Some might want to go more aggressive.
Also, a 4s would need less offset in the rear.

Thanks for the info! I am also looking for normal street use on 19". So i guess:
F 19x9 45mm
R 19x11 60mm
with 245-40-19/285-35-19 tires

would get me pretty close to stock?

lunarx

Yes, those diameters keep you close to stock.
For street, you can look at: 295-35-19, for the rear, but with a 63mm rear wheel offset.
(This tire size not available in track tires).

Looking at these OZ wheels, what would be the tire size I shod go with for a C2S? I wanted to keep them close to stock. Punching the number into willtheyfit dot come, there seems to be changes to the ride height due to the slight diameter shift. Will i need an alignment when swapping for the 19"? Will the shift in height and speedo error concerning? Trying to close to stock as possible.
