Staggered 18" 2-Piece Forged Wheels for 2020 Toyota GR Supra | Gloss Black & Red

Engineering Notes

Wheel diameter is part of the engineering brief rather than an afterthought. Staying at 18 inches leaves additional tire sidewall compared with a larger rim, while the existing project notes specifically connect the smaller format with lower rotational mass.

Two-piece construction gives the face a very different character from a clean monoblock. Hardware remains deliberately visible around the center, and the separate outer section provides the depth needed to make an 18-inch wheel look purposeful rather than visually small.

Front sizing is 18×9 ET32; rear sizing moves to 18×10 ET40. Only one inch separates the widths, which keeps the stagger controlled while still giving the rear more substance. Finished weight remains 11.8 kg at all four positions despite the dimensional difference.

Web-spoke geometry brings a dense network of lines into a relatively compact face. Gloss black suppresses some of that visual activity, while red accents break the dark surface at selected points. Big-brake clearance was already included in the existing engineering brief, so spoke position also has to serve a functional purpose behind the styling.

From Design to Delivery

• 100% CMM dimensional inspection
• Dynamic balancing
• 2-piece assembly torque check
•  Gloss finish QC

Result

Compact diameter gives the Supra a more competition-influenced proportion, but exposed hardware stops the wheel from appearing visually plain. Mechanical detail remains visible around the perimeter, while the web center adds density where a simple five-spoke design would feel much quieter.

Red works because it is restrained. Small accents interrupt the black face without competing with the spoke architecture, leaving the wheel looking technical rather than simply two-tone.

Eighteen inches was chosen to keep the wheel-and-tire package performance focused rather than simply making the rim larger. More tire sidewall remains visible around the forged face, while exposed assembly hardware gives the compact wheel a distinctly mechanical appearance. Gloss-black web spokes carry most of the visual detail, with red accents used sparingly to sharpen selected areas. Each finished wheel is recorded at 11.8 kg.

1. Why does this GR Supra use 18-inch forged wheels?

Smaller diameter leaves more visible tire sidewall, and the existing project notes also associate the 18-inch format with lower rotational mass.

2. What are the front and rear sizes?

Front wheels are 18×9; rear wheels measure 18×10.

3. How much does each wheel weigh?

All four wheels are listed at 11.8 kg.

4. Is this a genuine 2-piece forged wheel?

Yes. The specification lists 2-piece forged construction with visible assembly hardware.

5. Does the wheel allow space for upgraded brakes?

Existing Engineering Notes state that big-brake clearance was included in the design.

6. Why are the red details kept limited?

Restrained color placement keeps the web-spoke geometry dominant and prevents the compact 18-inch face from becoming visually crowded.

7. Can another Supra use a wider rear wheel?

Yes. Brake clearance, tire choice and required stance should be reviewed before changing the rear width or offset.
