The Short Version
- D9R is XD9, renewed. WORK’s own catalogue gives the internal part codes: XD9 is
EMT-D9, D9R isEMT-D9R. The R suffix marks a model renewal, and the same pattern gave us T7R from XT7. - XD9 is out of production. If you want one it is a used purchase.
- “CR Ultimate” is not a WORK model. It is an English translation of CR 極 (Kiwami), used by a US distributor. WORK’s own lineup has no such name.
- There is a newer wheel almost no English source has covered: CR 至極 (Shigoku), launched 1 December 2025. Kiwami is now the previous-generation CR face, still sold on purpose alongside it.
- And one for the sourcing nerds: the domain most English articles cite as WORK’s official site is not WORK. Details below.
Start With the Part Numbers
Model lineage arguments usually go in circles because everyone is describing the same wheels differently. The way out is to stop looking at the marketing name and look at the code WORK prints in its own catalogue.
XD9 is EMT-D9. D9R is EMT-D9R. That is not a coincidence and it is not our inference — it is on the page. D9R is the model change of XD9, with the same deep-rim concept and noticeably thinner, more tightly drawn spokes. The identical convention produced T7R as the renewal of XT7.
Once you see that, the whole Emotion naming system stops being mysterious. The X-prefixed models (XT7, XD9, and the eight-spoke XC8 that sat between XD9 and the 11R) are the first-generation Emotion wheels from the mid-2000s. The R-suffixed models are their renewals. What we could not find is any WORK statement explaining what the letter X itself stands for, so we are not going to tell you.
Where the Emotion Line Came From
WORK’s own developer has given the history in a Japanese interview, and it is more interesting than the catalogue suggests. The wheel that became the Emotion started as an unnamed F3 racing wheel. When WORK commercialised it they wanted a name reflecting 感動 — emotional impact — but an internal product from fifteen years earlier already used something too close, and the trademark position pushed them to “EMOTION” instead.
CR marks the cast, mass-produced street version released alongside the forged racing wheels. We can confirm that lineage from the interview. We could not confirm what the two letters literally abbreviate, so treat any confident expansion you read elsewhere as someone guessing.
極 (Kiwami) means the ultimate, or the perfected thing. WORK’s developer calls CR Kiwami 文字通り極めた商品 — literally the product that mastered the CR concept. It introduced WORK’s flow-forming process and a true concave face.
The Three Wheels, Compared
| XD9 | D9R | CR Kiwami | |
|---|---|---|---|
| Status | Discontinued | Current | Current |
| Construction | One-piece cast, flow-formed rim | One-piece cast, flow-formed rim | One-piece cast, flow-formed rim |
| Face | Deep rim, not concave | Deep rim, thinner and tighter spokes | True concave, twin five-spoke |
| Diameters | 17, 18 | 17, 18, 19 | 15, 16, 17, 18, 19 |
| Widths | 17: 7.0–9.5J · 18: 7.5–10.0J | 17: 7.0J · 18: 7.5–10.5J · 19: 8.5–10.5J | 15: 5.0J and 8.0J · 18: 7.5–10.5J |
| Standard PCD | 4H-100, 5H-100, 5H-114.3 by width | 5H-114.3 mainly, 5H-100 on some 18in widths | 15/16in: 4H-100 · 17/18in: 5H-100 and 5H-114.3 · 19in: 5H-114.3 |
| Offsets | +18 to +53 (17in), +18 to +45 (18in) | +12 to +53 by width | +5 to +45 (15in), +12 to +53 (18in) |
| Rim profile | Reverse (18in), normal (17in) | Reverse (18/19in), normal (17in) | Concave face rather than a reverse-rim split |
Which One for Which Car
The PCD table answers this more honestly than any styling argument.
CR Kiwami is the only one of the three available down to 15 and 16 inches with a standard 4H-100 fitment. That makes it the pick for older and smaller Japanese chassis — older Civics and Integras, compact front-drive platforms, the 4×100 world generally — as well as for the usual 17 to 19 inch five-lug crowd.
D9R is five-lug territory. It is centred on 5H-114.3 with some 5H-100, and WORK’s own big-caliper fitment guide lists it against modern JDM performance cars: Supra A90, GR Yaris, RC F and GS F, Mark X, Crown, 86 and BRZ, WRX STI, Evo X, S14 and S15, R32 to R34. We found no confirmed 4×100 offering for D9R, so it is not the wheel for a small four-lug car.
XD9 is a period piece now. Its own fitment guide targets the R32–R34 GT-R, S13–S15, DC5 Integra, FC and FD RX-7, Evo 5–9 and the GC8 Impreza era. If you are building a period-correct car from that generation, it is the correct wheel and it is only available used.
The New One: CR Shigoku
On 1 December 2025 WORK launched CR 至極 (Shigoku), shown at Tokyo Auto Salon in January 2026. It is the first new CR face design in about fifteen years, and it reframes how CR Kiwami should be described.
WORK’s own booth messaging spells the name out: 至極 means “beyond the ultimate” — explicitly positioned as the step past 極. The wheel keeps the twin five-spoke concave family but adds CNC machining to the sides and backs of the spokes, with WORK citing roughly 500 to 700 grams saved per wheel and a load rating raised from 700 kg to 720 kg. Finishes are Armed Titanium, Glow Gunmetal and Ice White, and unlike Kiwami there is no custom-colour programme.
The important point for a buyer: WORK has said it is not discontinuing Kiwami. The two are sold alongside each other because they are different faces — Kiwami’s concave is softer and more gradual, Shigoku’s is sharper and straighter, with undercuts at the nut holes and at the rim-flange joint. This is a choice, not a replacement.
Made to Order, and What That Means for You
The Emotion line is built to order. WORK states plainly that made-to-order production takes longer than off-the-shelf stock. We could not find a specific published lead time in weeks from a page we were able to read, so treat any precise figure you see quoted as unverified.
Practically, this is why used Emotion wheels hold value and why a good used set in a size you actually want is worth moving on. It is also why colour matters more than usual: the custom-order Colorism palette for Kiwami — blue, red, mint, green, pink, orange, yellow — means a used set in an unusual colour was a deliberate order by someone, and it may be the only set in that combination you will see.
On Counterfeits
WORK’s developer has said directly that cheap imitations of CR Kiwami and ZR10 circulate online. WORK also maintains a counterfeit-warning notice on its own site. We were unable to render the full text of that notice — the page is script-driven and did not return readable content to us — so we can tell you it exists and what it concerns, but we are not going to quote text we did not read.
Our general method for checking a WORK wheel is in Real or Fake WORK Wheels, and the cross-brand version is in Spotting a Fake JDM Wheel.
A Sourcing Note Worth Making Public
While researching this we checked the domain that a great deal of English-language WORK content cites as the manufacturer’s site. It is not. That domain belongs to a retailer — a WORK Pro Shop, which is an authorised dealer — and describes itself as such on its own pages. WORK Company Limited’s own site is a different domain.
This is not a criticism of the retailer, whose technical pages are good. It matters because a specification read off a dealer page is a dealer’s summary, and a specification read off the manufacturer’s catalogue PDF is the manufacturer’s own document. Where we could get the second, we used it, and we have said above where we could not.
What We Could Not Verify
- What the letters CR literally abbreviate. The lineage is confirmed; the acronym is not.
- The exact date XD9 went out of production. It is absent from WORK’s current lineup and treated as superseded, but we could not read a dated production-end notice.
- The full text of WORK’s counterfeit notice.
- A specific published made-to-order lead time.
- Whether WORK itself offers a structural rim or disc rebuild service. Repair parts — centre caps, stickers, valve stems — are listed; a rebuild service is not confirmed.
- JWL and VIA marking confirmed on the CR Kiwami, XD9 and D9R product pages by name. WORK is a JAWA member and marks its Japanese-market wheels as standard practice, but we could not open the model-specific pages to confirm it model by model.
- CR Kiwami’s full width, offset and PCD table at 16, 17 and 19 inches, and whether any single size is offered in multiple face depths. Only the 15 and 18 inch data was available to us, and from a distributor rather than a Japanese spec sheet.
- CR Shigoku’s per-size specification table.
