Two very different cars share one name and one fitment. The Z30 Soarer — sold as the Lexus SC300 and SC400 — is a 1990s grand tourer that became a drift and street icon. The SC430 that replaced it is a folding-hardtop convertible aimed at an entirely different buyer.
Both are 5×114.3 with a 60.1 mm bore and M12x1.5 studs. Both run a square setup with no factory stagger. And both sit at high offsets that leave a great deal of room to work with.
Section 1: OEM Wheel Specifications
| Model | Chassis Code | Years | Bolt Pattern | Hub Bore | Thread | OEM Wheel / Tyre |
|---|---|---|---|---|---|---|
| Soarer 2.5 Twin Turbo | JZZ30 | 1991-2001 | 5×114.3 | 60.1 mm | M12x1.5 | 7Jx16 ET50 / 225/55R16 |
| Soarer 3.0 / SC300 | JZZ31 | 1991-2001 | 5×114.3 | 60.1 mm | M12x1.5 | 7Jx16 ET50 / 225/55R16 6.5Jx15 ET50 / 215/60R15 |
| Soarer 4.0 / SC400 | UZZ31 / UZZ32 | 1991-2001 | 5×114.3 | 60.1 mm | M12x1.5 | 7Jx16 ET50 / 225/55R16 6.5Jx15 ET50 / 215/60R15 |
| SC430 | UZZ40 | 2001-2010 | 5×114.3 | 60.1 mm | M12x1.5 | 8Jx18 ET45 / 245/40R18 |
Front and rear wheels are identical on every model listed. The 4.0-litre UZZ32 was the Active Suspension car, which shares the standard fitment.

Section 3: The Z30 Soarer — Wide Body, Narrow Wheel
The Z30 is a physically large coupe. It is 1,790 mm wide, and it left the factory on a 7-inch rim at ET50. That combination produces one of the largest arch gaps of any car in this series, and it is exactly why the Soarer became such a canvas.
Realistic fitments:
- 18×9 ET30 / 18×9.5 ET25 — a clean upgrade. Fills the arch, no body work on a standard-height car.
- 19×9.5 ET22 / 19×10.5 ET15 — the modern staggered look. Fender roll and camber at the rear.
- 18×10 ET0 and beyond with over-fenders — the drift and street-style route. The JZZ30 in particular is heavily represented here.
Because the factory offset is so high, the Soarer tolerates enormous fitment changes before it needs cutting. That is the same property that made the Chaser JZX100 a drift favourite, and the two cars share a great deal mechanically.

Section 4: The SC430 Is a Different Proposition
The SC430 arrived with an 8Jx18 ET45 as standard — an inch more rim, two inches more diameter and five millimetres less offset than the Z30. It is a much more finished factory fitment, and consequently there is less obvious room to improve.
What works on an SC430:
- 19×8.5 ET35 / 19×9.5 ET35 — the natural step up. Roughly 10 mm more poke per side.
- 20×9 ET30 / 20×10 ET25 — the executive-convertible look. Watch tyre availability at 20 inches with a low profile.
- 18×8 ET45 — a straight factory-equivalent replacement.
The SC430 is a heavy car with a folding metal roof; it weighs around 1,750 kg. Wheel weight and load rating are real considerations, not styling footnotes. Look for the JWL and VIA stamps on any used Japanese wheel.
Section 5: What Fits From Elsewhere
The 60.1 mm Toyota bore gives the SC and Soarer access to the widest fitment pool in the Japanese market:
- Supra, Chaser, MR2, Celica, Lexus IS, LS400 — all direct fits. See our Supra guide.
- Nissan wheels (66.1 mm) — fit with a 66.1–60.1 hub-centric ring. This is why Silvia and Skyline wheels turn up on so many Soarers.
- Evo and RX-7 FD wheels (67.1 mm) — fit with rings.
- Honda wheels (64.1 mm) — fit with rings, though Honda offsets are generally too high to suit.
Remember the direction of the rule: a larger bore can be reduced with a ring; a smaller bore cannot be enlarged. Toyota’s 60.1 mm is the smallest common Japanese bore, which means Toyota hubs accept almost everything and Toyota wheels fit almost nothing else.

Buying Wheels for Your SC or Soarer
Square setup, one bolt pattern, one bore, generous arches. The SC and Soarer are among the least demanding cars in this series — the only real decision is how far past the factory offset you want to go.
