The iconic RAYS Engineering Volk Racing TE37 wheel is celebrating its 30th birthday in 2026.
From pancakes to pets, it does seem that everything has its own commemorative day now. But this latest addition to the calendar is one petrolheads can genuinely get behind, as March 7 has officially been declared TE37 Day.
Recognised by the Japan Anniversary Association, the date now stands as the annual celebration of one of the most iconic aftermarket wheels ever produced. A fitting tribute considering the Volk Racing TE37 itself turns 30 this year, having first debuted back in 1996.
And of course, to mark the milestone, RAYS Engineering has rolled out a set of special TE37 30th Anniversary editions. Available in the signature bronze or white, these commemorative models gain a series of subtle but meaningful highlights, including the return of heritage spoke decals (black on bronze, blue on white) to precision-machined spoke logos that highlight the forged construction. Each wheel is further stamped with a dedicated 30th Anniversary marking on the outer lip, serving as a permanent reminder of its legacy.
These commemorative rollers will be offered in three of the brand’s most recognisable modern formats: the TE37 Saga S-plus for five-lug applications, the compact TE37 Sonic for four-lug cars, and the TE37ultra Large P.C.D. for larger performance machines.
Naturally too, it wouldn’t be a proper Japanese anniversary celebration without a strong merchandising push. Alongside the wheels themselves, Rays has prepared a range of commemorative goods including TE37 pin badges created in collaboration with LEEN, key tags and anniversary T-shirts. In true Japanese fashion, the lineup even extends to collectible acrylic display stands and — somewhat charmingly — a small rubber duck wearing a racing helmet.
Forged from a single piece of aircraft-grade aluminium, the TE37’s name is rooted in its engineering ethos. “TE” stands for Touring Evolution, while the “37” refers to its astonishingly low weight of roughly 3.7 kg for the original 15-inch wheel. A figure that was virtually unheard of for a road-going wheel when it debuted.
The TE37 lineup expanded rapidly soon after launch. By 1997, a 16-inch version arrived as performance cars began shifting toward larger diameters. A lighter competition-focused model followed in 1998, and by 1999 a reinforced rally-oriented version had joined the range. In 2001, a Large P.C.D. variant opened the door for SUVs and pickups to adopt the six-spoke icon.
From there, the TE37 family steadily evolved with deeper lips, lighter refinements, track-oriented versions and even multi-piece interpretations, now numbering well over 30 variants. Yet despite all that evolution, the core design has remained largely unchanged, and its simple six-spoke form is now one of the most recognisable wheel silhouettes in the automotive world.
