I've looked at a lot of wheels over the years. Cast, flow-formed, forged. Japanese, German, Italian, American. Track wheels, street wheels, wheels that look great but weigh a tonne. And after all of it, I keep coming back to the same answer when someone asks me which wheel is objectively the best for a JDM performance build: Rays Volk Racing TE37. It's not even a close conversation.

The TE37 has been in continuous production since 1996. Nearly thirty years. The design has barely changed because it didn't need to. It was right the first time. A six-spoke monoblock forged aluminium wheel that became the benchmark against which every other JDM performance wheel is measured. Understanding why means understanding what makes a wheel genuinely good versus merely looking good.

The Engineering Behind the Spokes

The TE37's six-spoke design is not aesthetic. It's structural. Each spoke follows a specific geometry that distributes load efficiently between the hub and the rim. The spokes taper — thicker at the hub where stress concentrates, narrower toward the barrel. This distributes material where it's needed and removes it where it isn't, which is how you make something strong and light simultaneously.

The manufacturing process is 3D cold-forging. Rays starts with a billet of 6061-T6 aluminium alloy and forges it under enormous pressure into the near-final shape. The forging process aligns the aluminium's grain structure along the stress lines of the spoke geometry, producing a wheel that is denser and stronger than casting allows. Machining then removes material and creates precise geometry. The result is a wheel that is simultaneously lighter than a comparable cast wheel and significantly stronger.

A typical TE37 in a common size like 17x9 weighs around 6.7-7.2kg depending on offset. A quality cast wheel in the same size might weigh 9-10kg. Each wheel you save 2-3kg of unsprung rotational mass. Multiply by four wheels and the difference in handling, acceleration, and braking is substantial and measurable.

The Variants

Rays has produced numerous TE37 variants over the decades. The TE37 SL (Super Lap) is the track-focused version with a lighter construction aimed at circuit racing. The TE37 Ultra is the current production version with an updated spoke profile and improved weight reduction. The TE37 Saga is specifically designed for high-offset applications on modern wide-body cars.

For classic JDM builds, the original TE37 in silver or the bronze anodised finish remains the definitive choice. On a white or black car, bronze TE37s are one of the most timeless wheel combinations in the scene. On red or orange cars, silver TE37s. These aren't fashion choices — they've been proven correct by decades of builds.

The CE28N: The TE37's Sharper Brother

No Rays wheel guide is complete without mentioning the CE28N. If the TE37 is the balanced choice, the CE28N is the track-focused alternative. Eight spokes, lighter than the TE37 in equivalent sizes, with a design optimised specifically for circuit duty. Honda enthusiasts in particular love the CE28N for Type R applications — the eight-spoke design sits visually correctly in Honda wheel arches in a way that's harder to achieve with the TE37.

The RE30 rounds out the trio. Five spokes, even lighter than the CE28N in some sizes, originally developed for endurance racing applications. The RE30 is rarely seen because it's expensive and relatively uncommon, but it's possibly the finest wheel Rays makes from a pure engineering standpoint.

Genuine vs Fake

The most important thing to know about TE37s: the counterfeit market is enormous. Fake TE37s exist at every price point and they're sometimes convincingly labelled. A genuine Rays TE37 is marked on the inner barrel with the Rays QC stamp, has a serial number, and can be verified through Rays' authentication system. The spoke profile on genuine wheels has a specific chamfer and finish that's difficult to replicate cheaply.

Buying through authorised distributors is the safest approach. Price is also an indicator — genuine TE37s are not inexpensive. A real set in popular sizes costs $1,200-2,000 USD new. Anything significantly below that is almost certainly not genuine.

At Grovexo we only stock genuine Rays products, and we can help verify the authenticity of any Rays wheel you're considering. Don't compromise on wheels. The TE37 earned its reputation over thirty years of real racing. That reputation is worth paying for.
