McLaren 600LT P13 (2019-2020) Wheel Fitment Guide
The McLaren 600LT uses a 5×112 bolt pattern, a 57.1mm center bore and M14×1.5 ball-seat lug bolts, with factory part listings showing ET32.75 front and ET37 rear. This guide covers the US 2019 600LT Coupe and 2020 600LT Spider: factory wheels, documented aftermarket setups, carbon ceramic brake clearance and the tighter front arch at full lock.
About this guide: Fitment data is compiled from owner builds on McLarenLife and customer cars in wheel-maker and fitment galleries, cross-checked against vendor fitment documentation. Use it as research for your build; ride height, tires, and alignment are still your installer's call.

Factory Wheel & Tire Configurations
The Coupe and Spider share the hub hardware below and the same staggered factory sizes, 19×8 front and 20×11 rear on 225/35R19 and 285/35R20 tires. Part listings for the factory forged wheels show ET32.75 front and ET37 rear, the reference for every "mm out" figure in the aftermarket section below.
Applies To600LT Coupe MY2019 · 600LT Spider MY2020
McLaren's US launch release lists this forged 10-spoke as standard, on bespoke Pirelli P Zero Trofeo R tires; dealer listings also show cars delivered on P Zero. A gloss black ultra-lightweight front listing shows ET32.75, but we didn't find a rear listing with this style's offset, so check the stamp before ordering a build based on it.

Aftermarket Options
Aftermarket Wheel & Tire Configurations
Both factory wheels sit at 19×8 ET32.75 front and 20×11 ET37 rear, so each card below is one aftermarket wheel size and each row on its ladder is one documented build at its effective offset. The Front and Rear figures on each row show how far that build's outer lip sits outside the factory wheel. None of the documented 600LT builds used spacers.
Tap a setup to jump to its full card. Fit: Bolt-on = documented at stock ride height with no fender work reported · Lowered = documented on lowering springs or coilovers · Not reported = owners didn't say. Sources = owner builds (including customer cars in vendor galleries) and vendor fitment-guide setups documented on that card.
The front is the tight axle on the 600LT, and owners who have had both cars report less front room than on a 570S, which they put down to the wider front track and the 600LT's own front liner. One owner's 20×9 ET32 set on 245/30R20 tires fit his 570S but wouldn't reach full lock on his 600LT until the wheels were machined to ET37. Tread width also varies by tire model at the same size.
Carbon ceramic brakes.
Every US 600LT has carbon ceramic brakes, 390mm front with six-piston calipers and 380mm rear with four-piston. Vendor documentation shows 19×8.5 and 20×11 designs clearing them. Tell us your brakes when you order so caliper clearance is checked against them.
Lug bolts.
The factory bolts are M14×1.5 with a ball (radius) seat. FMB machines 600LT 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.

The closest documented step up from stock: half an inch more front width on a factory-width 20×11 rear, with both lips within about 8mm of the factory wheel. The same vendor's brake-clearance note lists the rear at ET32, about 5mm further in, so settle the rear offset before ordering.

The only 20/21 size documented at stock ride height with no rubbing reported. Treat the front as the limit: another owner's 20×9 ET32 front on 245/30R20 tires wouldn't reach full lock on his 600LT and only cleared after machining to ET37, so tire model and a few millimeters of front offset matter here.

Two builds show how differently the same size can sit. The ET38 front lines up almost exactly with the factory wheel while its rear sits about 18mm out; the ET27 front sits about 12mm out with a milder rear. If you're keeping stock height and a 245 front, start from the top row.

The most outboard documented front, and the only build that widens both ends while keeping the factory 19/20 diameters, with both lips 17–19mm outside stock. Tires and ride height weren't reported, and the front arch is the 600LT's tight spot, so check full-lock clearance with your exact tire before committing.

A 20-inch setup at both ends, with the most outboard documented rear at about 22mm outside stock. The 235/30R20 front keeps the tread narrower than the 245s owners report rubbing at full lock. Its front-to-rear rolling diameter ratio differs from the factory package, so check it against your owner's handbook.

Was this guide helpful?
Let us know how we did on Google.
Your feedback helps other owners find these free fitment guides. It takes about 30 seconds.
Built to the exact spec, not the closest one on a shelf. The setups above come from real 600LT 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 600LT 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 600LT: 5×112 bolt pattern, bored to the 57.1mm 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.
What are the factory wheel specs on the McLaren 600LT?
Both factory wheels are forged and staggered, 19×8 front and 20×11 rear, on 225/35R19 and 285/35R20 tires, with ET32.75 front and ET37 rear on the documented part listings. The 10-Spoke Ultra-Lightweight was standard and the 5-Spoke Ultra-Lightweight was optional. Owners commonly fit 235/35R19 fronts and 305/30R20 rears on the factory wheels.
What are the bolt pattern, center bore, and torque specs?
The 600LT uses a 5×112 bolt pattern and a 57.1mm center bore. The factory M14×1.5 lug bolts have a ball (radius) seat and are torqued to 130 Nm (96 lb-ft). FMB machines 600LT 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 fit a 600LT at stock ride height?
Two sizes are documented at stock height: 19×8.5 ET33 / 20×11 ET29 from vendor fitment documentation on factory-size tires, and 20×9 ET32 / 21×12 ET38 on a 2019 600LT with 245/30R20 and 325/25R21 tires and no rubbing reported. Both sit within about 13mm of the factory wheel at each end.
What's the difference between flush and aggressive fitment, and how do I read the offset ladder?
Each card is one wheel size and each row is one documented build at its effective offset. The Front and Rear figures show how far the outer lip sits outside the factory wheel. On the 600LT, up to about 13mm reads as flush; builds with a front 17mm out or a rear 18–22mm out are the aggressive end.
Do I need to worry about brake caliper clearance?
Every US 600LT has carbon ceramic brakes, 390mm front with six-piston calipers and 380mm rear with four-piston, the same brakes as the 720S. Vendor documentation shows 19×8.5 and 20×11 designs clearing them, but clearance depends on the barrel and spoke profile. Tell us your brakes and our manufacturing partner checks caliper clearance before production.
What's the widest front tire that fits the factory 600LT wheels?
On the factory 19×8 front, owners report 235/35R19 fitting and 245s rubbing at full lock with several tire models, including Toyo R888R; one owner reports 245/30R19 Michelin Pilot Sport Cup 2 Connect fitting. Rears up to 305/30R20 are commonly run with no rubbing reported. Keep overall diameters close to the factory front-to-rear ratio.
Can I run a square setup on the 600LT?
We haven't found a documented square 600LT build. McLaren only offered staggered wheels, and the stability systems compare front and rear wheel speeds, so owners keep the front-to-rear diameter ratio close to the factory 19/20 package. One documented build runs 20-inch wheels at both ends, but still with a much wider rear.
What about spacers on the 600LT?
Owners report the hub's roughly 11mm centering lip rules out 10mm spacers, and thicker spacers need longer bolts. None of the documented 600LT builds here use spacers. Spacer builds on our guides are listed at their effective offset, and FMB forges that offset directly, so the spacer isn't needed.
What are the best winter wheel options for the 600LT?
We didn't find a McLaren winter wheel package for the 600LT. Owners running winter or all-season tires typically use the factory 19×8 / 20×11 sizes, which keeps overall diameters at stock, so those sizes and offsets are the safest reference for a dedicated cold-weather set.
Which model years and models does this guide cover?
US-market 600LT Coupes were sold as model year 2019 and 600LT Spiders as model year 2020, including the final Segestria Borealis cars. Both share the same wheels, hub and brakes, so one guide covers them. The 570S, 570GT and 720S have different factory offsets or bodywork and aren't covered here.
Are 570S and 720S wheels interchangeable with the 600LT?
They share the 5×112 pattern and 57.1mm bore. Factory 570S wheels (19×8 ET32.5 / 20×10 ET24.25) sit within about a millimeter of the 600LT lip position, but owners report less front room on the 600LT, so 570S aftermarket specs don't always carry over. Factory 720S wheels (19×9 ET41.65 / 20×11 ET24.75) sit about 4mm out front and 12mm out rear.
