@Idenkr, correct! And from what I am reading, the tires you put on them will make a difference as well.
Here is what I found:
For a 991 Turbo S, these wheels work best with the stock overall diameters and a tire that runs a little narrow in section width (rounded shoulders):
Front (20×9 ET52): 245/35-20 — no issues here.
Rear (20×12 ET47): 305/30-20 — pick a model that runs truer/narrower to size to keep the sidewall from poking.
Good “narrow-ish” choices for the rear in 305/30-20:
Continental ExtremeContact Sport 02
Pirelli P Zero (PZ4)
Avoid super-wide/boxy options (e.g., Michelin Cup 2 / Cup 2 R, and even PS4S in 305) as they tend to measure wider.
For max clearance, a 295/30-20 rear will tuck even better—just note it’s a mild stretch on a 12" rim, so confirm the tire’s approved rim-width range. A touch more rear negative camber (≈-1.6° to -1.8°) also helps prevent rub under load. If you prefer to go that route.

ok so they should fit but might be slightly outward in the rears? hopefully not past the width of the fenders?

@Idenkr - Hey, hope all is well. Based on the research I did; The wheels are OEM 991.1 GT3 spec (20×9 ET55, 20×12 ET47). The Turbo S factory fitment is very close — 20×9 ET51 front and 20×11.5 ET56 rear. The fronts are effectively the same, and the rears are just a touch wider and sit slightly further outward. Many Turbo S owners run GT3 wheels without issue, but the rears will look a bit more aggressive compared to stock. I am not a wheel expert, however.
A great source to use is the Apex Wheel Fitment Guide: https://apexwheels.com/fitment-guides/porsche
Hello I have a 2015 911 Turbo S 991.1. Would these fit without rubbing or modification?
@JayC67 - Hey sorry for the delay. I got an answer but probably not the one you wanted.
A typical GT4 RS (incl. PCCB) runs about 20×9 ET53 front and ~20×11 ET50 rear. Compared to that, the 12-inch rears here are 1.0" wider and 3 mm less positive offset, which means they’d sit ~9.7 mm further outboard and ~15.7 mm closer to the inner suspension. Per my lead mechanic at Autometrics, that’s too aggressive for a GT4 RS on stock alignment/liners—likely rub. Fronts should be fine; rears are not a direct fit without modifications (significant camber and/or body/liner work).”

@jayC67 - Hey! Thanks for the question! These are OEM 991.1 GT3 center-lock wheels (20×9 ET55 front, 20×12 ET47 rear). A GT4 RS runs 20×8.5 ET61 front, 20×11 ET50 rear from the factory and its PCCB rotors are 410 mm front / 390 mm rear. So the GT3 wheels are wider (+0.5” F / +1.0” R) and sit further outward (about +6 mm F / +3 mm R). The big variable is caliper/barrel clearance with the 410 mm PCCB fronts. Because of the extra width and lower offsets, they might work, but I can’t guarantee fitment on a GT4 RS without a test-fit or a brake template. I’m not an expert on wheels but let me check with the guys at Autometrics tomorrow to see if they have a better answer.
Hi, would you know if these would fit a GT4RS with PCCBs?

Hi PCARMARKET community, greetings James here, owner of Por4mance Motors & Detail Garage in Summerville, SC. I’m the selling these OEM 20" GT3 wheels for my client. My shop focuses on Porsche-centric sales support and white-glove auto listings.
The wheels you see are exactly as photographed; I’m happy to provide any additional close-ups, measurements, or packaging pics upon request. Working directly with Autometrics Motorsports, we ship wheels all the time and will box and protect them properly. Shipping and insurance are at the buyer’s expense. Local pickup is also welcome.
Post-Auction, optional add-on for the winning bidder: I can professionally ceramic-coat the wheels (faces and barrels) before shipment. This includes full decon/prep and a high-temp, wheel-specific coating. We are a Gyeon certified detailer so we use Gyeon products but if the buyer requests another specific brand, we can discuss that post-auction. Turnaround is approximately 24 hours for the ceramic to cure; I’ll coordinate timing with the buyer. If you’re interested, just use the “Contact Seller” button and I’ll outline the details.
Thanks for looking, and good luck to all bidders!
—James, Por4mance Motors & Detail Garage
