Porsche 911 Carrera / Carrera S / Carrera T 991 (2012–2019) Wheel Fitment Guide
The 991 Carrera, Carrera S and Carrera T use the narrow rear body, a 5×130 bolt pattern, a 71.6mm center bore and M14×1.5 ball-seat lug bolts. Factory 20-inch offsets are ET51 / ET70 on 991.1 cars and ET49 / ET76 on 991.2 cars, which put the rear lip in the same place. This guide covers 2012–2019 coupes and cabriolets, PCCB clearance and documented aftermarket setups.
About this guide: Fitment data is compiled from owner builds on Rennlist and customer cars in wheel-maker fitment galleries, cross-checked against vendor fitment documentation and Porsche's approved wheel certificates. Use it as research for your build; ride height, tires, and alignment are your installer's call.

Aftermarket Wheel & Tire Configurations
Every card below is one wheel size, and every row is one documented build at its effective offset; spacer builds are listed at the offset a forged wheel would need and marked Via spacers. 991.1 and 991.2 narrow-body cars put the factory rear lip in the same place, so builds from either phase apply to both. Every documented build is staggered.

Platform-specific fitment notes — Porsche 911 Carrera / Carrera S / Carrera T 991
Narrow-body offsets.
991.1 cars run an 11J ET70 rear and 991.2 cars an 11.5J ET76 rear, which put the rear lip in the same place. Wide-body Carrera 4 and GTS rears sit 18–20mm further out and can pass these fenders, and many used 991 wheels are wide-body versions of the same designs. Check the stamp on any used 991 wheel.
Brakes and wheel size.
991.2 cars with ceramic brakes (PCCB, 410mm front rotors) need 20-inch wheels: Porsche doesn't approve the 991.2 19-inch Carrera wheel with PCCB, and a vendor lists 20s as required. On steel brakes, the 19-inch sets on this page are documented on Carrera, Carrera S and Carrera T cars, and caliper clearance is checked on every set.
Ball-seat lug bolts.
The factory bolts have a ball seat. FMB machines 991 Carrera wheels for 60° conical-seat bolts by default, so a new set runs conical bolts of the correct length. If you want to keep your factory ball-seat bolts, tell us when you order; otherwise the wheels are machined for conical. Most Porsche owners ask for ball seat.

The most documented narrow-body setup: a 9-inch front at ET41–45 with an 11.5-inch rear at ET62–72, on twelve 991.1 and 991.2 cars. At ET72 the rear lip stays within about 4mm of the factory wheel while the front comes out 10–14mm. If your car is at stock height, start from the ET44 or ET41 rows; the spacer rows sit further out.

A 9-inch front with an 11-inch rear, the width of the 991.1 Carrera's factory 19-inch wheel. At ET50 / ET60 it sits about 6mm out front and 10mm at the rear. Both gallery cars run it with no changes, one on the factory 235/40R19 / 285/35R19 tire sizes, which makes it a natural second set for 991.1 Carreras.

A 12-inch rear at the factory ET76 adds rim width while the rear lip moves out only about 6mm. It's one documented 991.2 narrow body on lowering springs, with rear-axle steering and the factory-size Pirelli tires, and its owner reports no problems. He adds that ET40 fronts would have filled the arch without the 5mm spacer he considered.

A 9-inch front with an 11-inch rear at a low rear offset, so the rear lip moves out 15–20mm: the most aggressive 20-inch rear on this page. Two of the three cars are 991.1 narrow bodies, one on lowering springs with no rubbing reported. If you want the rear to stay near stock, the 20×9 / 20×11.5 card is the closer fit.

The narrow-body track size: a 9.5-inch front for a 265 tire, about 15–18mm out, with the rear held near the factory lip. Both sources pair it with extra front camber; the owner build runs coilovers with camber plates and GT3 lower control arms. Plan the alignment with the wheels if you choose this card.

Our Process
What happens when you build with FMB
Built to the exact spec, not the closest one on a shelf. The setups above come from real 991 Carrera builds, and we CNC-machine every wheel to them directly. If a build needs a spacer to reach its offset, we machine that offset into the wheel instead.
- Choose your setup.
This guide is built to give you what you need to pick a spec with confidence: documented 991 Carrera builds, tire sizes, and how each one fits. If you still have questions, we're happy to help before you order.
- Engineering verification.
Our manufacturing partner confirms wheel specs, including bolt pattern, center bore, brake caliper clearance, backspacing and load rating.
- Render approval.
You approve the design and final specs before we move forward with production.
Our fitment guarantee
Every set is guaranteed to mount on your 991 Carrera, Carrera S or Carrera T: 5×130 bolt pattern, bored to the 71.6mm hub, machined for 60° conical lug bolts (or your factory ball-seat bolts if you request it when ordering), and made to the exact width and offset you approved.
How a setup sits on your car also depends on ride height, tires and alignment, so choose with your plans in mind.
Start your 991 Carrera build →Common Questions
FAQ — Frequently Asked Questions
What are the factory wheel specs on the 991 Carrera, Carrera S and Carrera T?
991.1 cars (2012–2016) use 8.5J fronts with 11J rears: 19-inch ET54 / ET69 on the Carrera and 20-inch ET51 / ET70 on the Carrera S, on 285/35ZR19 or 295/30ZR20 rears. 991.2 cars (2017–2019) moved to 11.5J rears: 19-inch ET50 / ET76 on the Carrera, and 20-inch ET49 / ET76 with 305/30ZR20 rears on the Carrera S and Carrera T.
What are the hub and lug bolt specs?
A 5×130 bolt pattern, 71.6mm center bore and M14×1.5 ball-seat lug bolts, torqued to 118 lb-ft (160 Nm) per Porsche's 991 certificates. FMB machines 991 Carrera wheels for 60° conical-seat bolts by default, so a new set runs conical bolts of the correct length. If you want to keep your factory ball-seat bolts, tell us when you order; otherwise the wheels are machined for conical.
What aftermarket wheel sizes are documented on the 991 Carrera at stock ride height?
The most documented setup is 20×9 at ET41–44 with a 20×11.5 ET72 rear, on nine 991.1 and 991.2 cars, mostly on factory-size 245/35R20 / 305/30R20 tires. A vendor lists ET41 / ET72 as typically fitting with no changes. On 19s, 19×9 ET50 with a 19×11.5 ET72 or 19×11 ET60 rear is listed the same way.
How do I read the offset ladder on each card, and what's the difference between flush and aggressive?
Each card is one wheel size and each row one documented build at its effective offset. The Front and Rear figures show how far the outer lip sits outside the 991.2 Carrera S wheel (8.5J ET49 / 11.5J ET76), or the 19-inch Carrera wheel on 19-inch cards. Up to about 14mm reads as a flush fill; 15–20mm is the aggressive end. Via spacers marks spacer builds.
What wheel sizes clear the 991 Carrera brakes?
991.1 Carreras use 330mm front rotors and Carrera S models 340mm, with 350mm ceramic brakes (PCCB) optional. On 991.2 cars the Carrera and Carrera T use 330mm, the Carrera S 350mm, and PCCB grows to 410mm front and 390mm rear. Porsche doesn't approve the 991.2 19-inch wheel with PCCB, and a vendor lists 20s as required on those cars.
Why is there no square setup on the 991 Carrera?
Every factory and documented setup is staggered, with a wider rear for the rear-engine weight bias, and we couldn't find a narrow-body square setup with published offsets. These cars are rear-wheel drive, so front-to-rear rolling diameter doesn't load a center differential, but changing tire sizes still changes gearing and the speedometer reading.
Can I use wheel spacers on the 991 Carrera?
Porsche approves a 5mm spacer per wheel on the 991.1 Carrera and Carrera S with the factory 19- and 20-inch summer sizes, fitted per its installation instructions. Owners on this page run 3–7mm spacers on aftermarket sets. Every spacer build is listed at its effective offset, and FMB machines that offset into the wheel instead.
Will Carrera 4, 4S or GTS wheels fit a 991 Carrera S?
Five-lug versions mount, since the hub, bore and bolts match, but wide-body rears are ET52 (991.1) or ET56 (991.2), about 18–20mm further out than the narrow-body rear, and can pass the fender. 991.1 and 991.2 narrow-body wheels swap with the rear lip in the same place and the 991.2 front about 2mm further out.
What are the factory winter wheel options?
Porsche's 991.2 certificate lists Carrera winter sets at 8.5J×19 ET50 / 11J×19 ET77 on 235/40R19 / 295/35R19, not approved with PCCB, rear-axle steering or the Power Kit, and 8.5J×20 ET49 / 11J×20 ET78 on 245/35R20 / 295/30R20. Rear snow chains are approved on both 991.2 rear sizes and on the 991.1 19-inch set, at up to 30 mph.
Which model years and cars does this guide cover?
The 991 Carrera, Carrera S and Carrera T coupe and cabriolet: 991.1 for 2012–2016 and 991.2 for 2017–2019, with the Carrera T for 2018–2019. In the VIN, the 10th character is C to G for 2012–2016 and H to K for 2017–2019. Carrera 4, Targa, GTS, Turbo and GT3 models use a different body or hub and aren't covered here.
