If you have read our Mugen article, NISMO is the useful contrast. Mugen has never had a capital relationship with Honda. NISMO has always been owned by Nissan.
People treat the two as equivalent because both are the “performance brand” of a Japanese manufacturer. Structurally they could hardly be more different.
The Short Version
- Founded September 1984 in Omori, Tokyo, by merging Nissan’s works motorsport division with its customer Sports Kit operation.
- A wholly owned Nissan subsidiary from 1984 to 2022.
- Merged with Autech on 1 April 2022 to form Nissan Motorsports & Customizing Co., Ltd. NISMO now exists as a brand within that company, not as a company itself.
- The LM GT4 is a forged one-piece wheel, 5×114.3, sold through a deliberately short list of retailers — one of which is RAYS.
- NISMO parts go through the Nissan dealer network. Unlike Mugen, they really are factory-channel parts.
What Was Created in 1984
NISMO was not started from nothing. In September 1984 Nissan brought together three things: its works racing division, the Sports Kit section that had been selling and supporting parts to customers out of the advertising department, and the Special Car Testing Division at the Oppama plant. Yasuharu Namba was the founding president.
That combination explains what NISMO has always been: a racing operation that also sells parts, inside the manufacturer rather than alongside it.
What Changed in 2022
On 21 February 2022 Nissan announced that Nissan Motorsports International would integrate with Autech Japan. The merger completed on 1 April 2022, creating Nissan Motorsports & Customizing Co., Ltd. — capital ¥480 million, roughly 600 employees, headquartered in Chigasaki.
The practical answer to “is NISMO still NISMO?” is yes. The brand was deliberately retained. What changed is the legal entity behind it: NISMO stopped being a company and became a brand and division inside a larger one, alongside Autech.
For a parts buyer this changes nothing you would notice. For anyone reading company records it changes what you are looking at.
The Racing Record
Group C from 1985 — the March 85G-Nissan won the WEC Japan round at Fuji that October.
Le Mans: the R90CP took fifth overall in 1990; the R33-based GT-R LM finished tenth in 1995; the R390 GT1 took third overall in 1998, which remains Nissan’s best result. The GT-R LM Nismo LMP1 ran in 2015.
Super GT: the R34 GT-R was campaigned from 1999 to 2003, winning drivers’ and teams’ titles in both its first and last seasons. The current GT-R GT500 has taken seven wins from nine races in a title year.
Formula E from the 2018/19 season — the first Japanese manufacturer in the series — with Sébastien Buemi winning the New York E-Prix in the debut season.
The LM GT4
The wheel most people mean when they say “NISMO wheels.” Forged, one-piece aluminium alloy, 5×114.3.
| Wheel | Size | Offset | Weight | Application |
|---|---|---|---|---|
| LM GT4 18″ | 18×9.0J | +22 | 8.9 kg | BNR32 |
| LM GT4 18″ | 18×9.5J | +12 | 9.3 kg | BCNR33 / BNR34 |
| LM GT4 18″ | 18×10.5J | +15 | 9.6 kg | tuner size |
| LM GT4 EVO 19″ | 19×9.0J to 19×10.5J | +39 to +25 | 9.3–10.1 kg | — |
On who makes it. NISMO’s own catalogue lists a short set of authorised retailers: the NISMO Omori Factory, the NISMO Performance Center, NISMO distributors — and RAYS Co., Ltd.
RAYS is a wheel manufacturer, and its presence on a list of authorised retailers for a forged wheel is a strong signal. But the catalogue page says retailer, not manufacturer. We are treating RAYS as very likely the maker and telling you exactly what the page does and does not say.
What This Means When You Are Buying
NISMO parts are genuine factory-channel parts. They go through Nissan dealers and Nissan parts sites. That is a different situation from Mugen, where Honda directs you to a separate manufacturer.
The short retailer list matters. A wheel that did not come through the Omori Factory, the Performance Center, a listed distributor or RAYS came from somewhere else. That is worth a question on a used set.
The 2022 merger is not a quality line. Nothing about the parts changed. If a seller implies pre-merger NISMO is somehow more authentic, that is a story, not a fact.
What We Could Not Verify
- Whether RAYS is the sole manufacturer of the LM GT4, or one of several. The catalogue lists RAYS as a retailer.
- The weight-saving figure for the LM GT4S on the Note Aura. A number circulates; we did not see it on an official page.
- The exact legal entity name at incorporation in 1984 beyond Nissan Motorsports International Co., Ltd.

Finding NISMO Wheels
Genuine LM GT4 sets come loose from cars in Japan and mostly stay here. Tell us the chassis and the size through the Request page — and if you are looking at a set someone else is selling, send us photographs of the back.
