Porsche 911 Carrera 4 / 4S, Targa 4 / 4S & GTS 991 (2013–2019) Wheel Fitment Guide
The 991 Carrera 4, Carrera 4S, Targa and GTS share the wide rear body, a 5×130 bolt pattern with a 71.6mm bore and M14×1.5 ball-seat lug bolts, and every GTS came standard on centerlock hubs. Factory 20-inch offsets are ET51 / ET52 on 991.1 cars and ET49 / ET56 on 991.2 cars. This guide covers 2013–2019 cars, both hubs, PCCB clearance and documented 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.

Every 991 wide-body car shares the hardware below, listed by hub. Porsche's certificates list 8.5J fronts on every Carrera 4 summer wheel, with 11J rears on 991.1 cars and 11.5J rears on 991.2 cars; the GTS centerlock wheels are wider. The 20-inch 991.2 Carrera 4S wheel (8.5J ET49 / 11.5J ET56) is the reference for every 20-inch "mm out" figure below.

Every card below is one wheel size, and every row is one documented build at its effective offset, marked by hub where known. 991.1 and 991.2 wide-body cars put the factory 5-lug rear lip within about 2mm of each other, so builds from either phase apply to both. Every documented build is staggered.

Platform-specific fitment notes — Porsche 911 Carrera 4 / 4S, Targa & GTS 991
991.2 rear offsets and camber.
The 991.2 GTS centerlock rear is 12J ET63, and a vendor lists ET63 rears for 991.2 Carrera 4 and GTS cars on 325 tires; with ET46–47 rears it lists about -2° of rear camber or more on 991.2 cars. Narrow-body rears (ET70–76) sit 18–20mm further in, so 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 4S and GTS cars.
Centerlock, 5-lug and lug bolts.
Every GTS came standard on centerlock hubs, with 5-lug Carrera S wheels as an option; the two wheels don't interchange, so order for your hub. 5-lug cars use M14×1.5 ball-seat bolts. FMB machines 5-lug 991 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. Centerlock cars use one central nut torqued to 600 Nm.

The most documented wide-body size: a 9-inch front with a 12-inch rear, the 991.2 GTS's own factory widths, on the factory 245/305 tire sizes. Five GTS cars run it at ET47 / ET47, and a vendor lists ET41 / ET47 for 5-lug cars. If your car is at stock height, start from the top row; the ET45 rear sat too far out for its owner.

The 19-inch dual-duty size for wide-body cars, on 255 or 265 fronts with 305 to 325 rears. The rear offset is the choice that matters: ET63 keeps the rear lip within about 1mm of the factory wheel, while ET46 moves it about 16mm out and, on 991.2 cars, needs more rear camber. Gallery Carrera 4S cars run ET46.

The closest step from stock on this page: a half-inch wider front with the factory 11.5-inch rear width, about 8mm out front and 6mm at the rear. It's one documented 991.2 Carrera 4S, and its owner called the result absolutely perfect. It keeps the factory 305 rear tire size, which makes it a simple first set.

The wide-body track size: a 9.5-inch front for a 265 tire with a 12-inch rear for a 325, about 11–18mm out front. Gallery GTS cars run it at ET45–50 with no changes listed, and an owner's rear-drive GTS has run ET52 / ET48 on Trofeo R tires for a year. Plan front camber with the wheels, and pick the ET63 rear on a 991.2 Carrera 4.

A 21-inch rear on a 991 wide body: one documented 991.2 GTS on later 911 GT3 centerlock wheels, about 16mm out front and 17mm at the rear against the 20-inch Carrera 4S reference. Its owner reports a flush fit and runs a 325/25R21 rear, which keeps the rear rolling diameter within about 1% of the factory 305/30R20.

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 4, 4S, Targa and GTS 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 4, 4S, Targa and GTS 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 4, 4S, Targa or GTS: made for your hub, either centerlock or 5×130 bored to the 71.6mm hub and 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 4 / GTS build →Common Questions
FAQ — Frequently Asked Questions
How do I tell if my 991 GTS has centerlock or 5-lug wheels, and do centerlock builds apply to a 5-lug car?
Centerlock wheels have one large central nut; 5-lug wheels have five bolts. Every GTS came standard on centerlocks, with 5-lug Carrera S wheels a factory option. The wheels don't interchange, but both hubs share the body and brakes, so a documented offset sits in the same place on either car. Order the wheel for your hub.
What are the factory wheel specs on the 991 Carrera 4, Carrera 4S, Targa and GTS?
991.1 cars (2013–2016) use 8.5J fronts with 11J rears: 19-inch ET54 / ET48 on the Carrera 4 and 20-inch ET51 / ET52 on the 4S. 991.2 cars (2017–2019) use 11.5J rears: 19-inch ET50 / ET56 and 20-inch ET49 / ET56. GTS centerlocks are 9J ET51 with an 11.5J ET48 (991.1) or 12J ET63 (991.2) rear.
What are the hub and lug bolt specs?
5-lug cars use a 5×130 bolt pattern, 71.6mm center bore and M14×1.5 ball-seat lug bolts at 118 lb-ft (160 Nm); centerlock GTS cars use one nut at 600 Nm. FMB machines 5-lug 991 wheels for 60° conical-seat bolts by default. 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 4 and GTS at stock ride height?
The most documented setup is 20×9 / 20×12 on the factory 245/35R20 / 305/30R20 tire sizes: five GTS cars in a vendor gallery run ET47 / ET47, and a vendor lists ET41 / ET47 for 5-lug cars. On 19s, 19×9 ET50 with a 19×12 rear is listed the same way on two 991.2 Carrera 4S cars.
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 4S wheel (8.5J ET49 / 11.5J ET56), or the 19-inch Carrera 4 wheel on 19-inch cards. Up to about 14mm reads as a flush fill; 15–20mm is the aggressive end.
What wheel sizes clear the 991 Carrera 4 and GTS brakes?
991.1 cars use 330mm front rotors on the Carrera 4 and 340mm on the 4S and GTS, with 350mm ceramic brakes (PCCB) optional. On 991.2 cars the Carrera 4 uses 330mm, the 4S and GTS 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.
Why is there no square setup, and do staggered setups work on the all-wheel-drive cars?
Every factory and documented setup is staggered, with a wider rear for the rear-engine weight bias, and we couldn't find a wide-body square setup with published offsets. On Carrera 4, 4S, Targa and 4 GTS cars, front-to-rear rolling diameter matters to the all-wheel-drive system: we document tire sizes on every card, and you should check them against your owner's manual.
Can I use wheel spacers on the 991 Carrera 4 or GTS?
Porsche approves a 5mm spacer per wheel on 991.1 wide-body 5-lug cars with the factory 19-inch Carrera V and 20-inch 8.5J ET51 / 11J ET52 summer sizes; its 991.2 certificate lists none, and centerlock hubs take none. Every spacer build is listed at its effective offset, and FMB machines that offset into the wheel instead.
What are the factory winter wheel options?
Porsche's 991.2 certificate lists Carrera 4 winter sets at 8.5J×19 ET50 / 11J×19 ET56, not approved with PCCB, rear-axle steering or the Power Kit, and 8.5J×20 ET49 / 11J×20 ET56 on 245/35R20 / 295/30R20. Centerlock GTS cars get an 8.5J ET51 / 11J ET59 set. Rear snow chains are listed for 295/30R20 at up to 30 mph.
Which model years and cars does this guide cover?
The 991 Carrera 4 and 4S coupe and cabriolet, Targa 4 and 4S, and Carrera GTS, Carrera 4 GTS and Targa 4 GTS: 991.1 for 2013–2016 (Targa from 2014, GTS from 2015) and 991.2 for 2017–2019. In the VIN, the 10th character is D to G for 2013–2016 and H to K for 2017–2019. Turbo and GT3 models use other bodies.
Will 991 Carrera or Carrera S wheels fit a Carrera 4S or GTS?
Five-lug narrow-body wheels mount, since the hub, bore and bolts match, but their ET70 (991.1) or ET76 (991.2) rears sit 18–20mm further in, so the rear looks tucked. Wide-body rears on a narrow-body car can pass the fender. The 991 Carrera / Carrera S / Carrera T guide covers the narrow body.
