Lexus RC F Wheel Fitment Guide: Offsets, Sizes & Specs
· Tony Song
Quick answer
The Lexus RC F (USC10, 2015 on) uses a 5×114.3 bolt pattern, a 60.1 mm centre bore and M12×1.5 wheel nuts torqued to 103 Nm. From the factory it runs 19x9 ET50 with 255/35R19 tyres at the front and 19x10 ET41 with 275/35R19 at the rear. For a flush fit, most owners move to a 19x9.5 front and 19x10.5 rear with lower offsets.

Why the RC F front looks tucked in
At ET50, the factory front wheel sits deep inside the guard, while the rear (ET41) sits much closer to the edge. That's why owners commonly add about 20 mm of spacer at the front and 15 mm at the rear to get the factory wheels flush. A custom wheel builds that position into the offset, so you don't need spacers.
RC F wheel fitments that work
| Setup | Front | Rear | Tyres (F / R) | What to expect |
|---|---|---|---|---|
| Factory | 19x9 ET50 | 19x10 ET41 | 255/35R19 / 275/35R19 | Front sits well inside the guard |
| Flush | 19x9.5 ET36–42 | 19x10.5 ET33–38 | 265/35R19 / 285/35R19 | Close to flush at factory ride height |
| 20-inch | 20x9.5 ET36–42 | 20x10.5 ET33–38 | 265/30R20 / 285/30R20 | Flush position with a lower-profile tyre |
| Aggressive | 19x10 ET35–40 | 19x11 ET25–30 | 275/35R19 / 295/35R19 | Usually lowered with camber adjustment. The rear guard lip may need rolling. |
These ranges assume factory ride height and alignment unless noted. The tyre sizes keep the overall diameter within about 2% of factory, so the speedo and stability control stay accurate.
Brake clearance and minimum wheel size
The RC F comes on 19-inch wheels, and that's the minimum we recommend for the road. Some purpose-built 18-inch track wheels clear the factory Brembo brakes, but it depends entirely on spoke shape. Cars with the carbon-ceramic brakes (Track Edition) need the same check. We test every design against a brake template before machining.
Before you order wheels for an RC F
- ✓Hub rings: most aftermarket wheels are bored bigger than 60.1 mm, so they need hub-centric rings. Custom forged wheels can be bored to exactly 60.1 mm.
- ✓Wheel nuts: the factory nuts are flat-seat, made for the factory wheels. Most aftermarket wheels need 60° conical-seat nuts.
- ✓TPMS: move your factory tyre-pressure sensors across, or have new ones registered to the car.
- ✓Alignment: get an alignment after fitting, especially with an aggressive setup or a lowered car.
Is it road-legal in Victoria?
Victorian rules
Under VSB 14, the national modification code, the wheel track (the distance between the left and right wheels) can grow by up to 25 mm (about 12.5 mm per side) over the widest factory option. VicRoads also limits the overall tyre diameter to 15 mm more than the largest factory size, and the tyres must stay covered by the guards. Flush and aggressive setups can go past these limits and may need a VASS certificate. We'll tell you where your setup sits before you order.
Lexus RC F wheel fitment FAQs
What offset fits a Lexus RC F?
For a flush look, ET36–42 on a 19x9.5 front and ET33–38 on a 19x10.5 rear. The factory offsets are ET50 front and ET41 rear.
Do I need spacers on an RC F?
Not with custom wheels, because the offset is built in. On the factory wheels, owners commonly use about 20 mm at the front and 15 mm at the rear.
Will RC 300 or RC 350 F Sport wheels fit an RC F?
They bolt on, since the hub is the same 5×114.3 / 60.1 mm. But they're narrower (19x8 ET45 front, 19x9 ET60 rear) and may not clear the RC F's larger brakes. Check clearance before fitting them.
Can I fit 20-inch wheels to an RC F?
Yes. 265/30R20 front and 285/30R20 rear tyres keep the overall diameter close to factory. Use the same offsets as the flush 19-inch setup.
