2008–2016 · coupe
The rear-wheel-drive Genesis Coupe came with staggered 18 or 19-inch wheels, the 19s going on the Brembo-equipped grades. Owners often move to wider staggered 19s on coilovers, and the 5x114.3 pattern opens up a large choice of Japanese and aftermarket wheels.

Read these before choosing wheels for the Genesis Coupe: they explain the offset, fitment and hub numbers in this guide.
Starting points for a build. Read the notes with each setup, especially if your car is lowered or has different brakes.
Threepiece's Genesis Coupe guide shows a BK1 3.8 Track on 18x8.5 ET33 all round at standard ride height, with no spacers and no rubbing. The guide gives two different tyre sizes for this car, so we have left the tyre out.
A 3.8 Track featured in Threepiece's guide runs 19x9.5 ET37 front and 19x10.5 ET30 rear on coilovers, with no rubbing reported.
A 2014 3.8 R-Spec in the same Threepiece guide runs 19x9.5 ET22 front and 19x10.5 ET22 rear on stiffly sprung coilovers, with no rubbing reported. This is the most aggressive setup here without arch work.
Check the exact setup
There is no confirmed range for this car yet. Compare a known wheel with your proposed size and measure both sides.
Measure before ordering
A maximum width has not been confirmed. Tyre shape, ride height and alignment all change the available space.
These figures belong to the setups described here. Combining the widest wheel with either end of the offset range does not guarantee a safe fit. For how ET moves the wheel in and out, read wheel offset explained; for how far the tyre can sit out, see flush, poke and tucked fitment.

These tools start with the BK1 (2010–2012), 18-inch, non-Brembo grades front size. Choose your own trim or axle in the calculator if it differs.
5x114.3 with M12x1.5 wheel nuts. Sources quote a hub bore of either 66.7 mm or 67.1 mm, so measure before buying rings.
Non-Brembo cars have 18x7.5 front and 18x8 rear with 225/45 R18 and 245/45 R18 tyres. Brembo cars have 19x8 front and 19x8.5 rear with 225/40 R19 and 245/40 R19. Offsets are ET33 or ET35 on the BK1 and ET30 to ET34 on the facelift.
Yes. Both use 5x114.3 and very similar widths and offsets. Hubcap Haven lists the facelift wheels at ET32 against ET33 to ET35 for the earlier car.
Factory 350Z wheels share the 5x114.3 pattern and clear the Genesis Brembos, but Threepiece recommends 10–25 mm spacers and notes the centre bore differs slightly.
19x9.5 front with 225/40 R19 or 245/35 R19 and 19x10.5 rear with 255/35 R19 or 275/35 R19, at ET22 to ET37, as run by the Track and R-Spec cars in Threepiece's guide.
