Japan Racing JR50

Buying Guide for Japan Racing JR50 Rims

The Japan Racing JR50 rims are among the more striking models in the range, combining a classic deep-dish design with modern manufacturing technology. Through the combination of a step-lip construction and flow-forming technology, this model is primarily aimed at drivers who want to combine a distinctive look with improved driving characteristics.

The JR50 rim is available in various diameters and widths, making it suitable for both custom vehicle projects and sporty daily setups. In this buying guide, you will learn about the characteristics of this model, the available sizes, and what to consider when choosing the right rim configuration.

Design and Features of the Japan Racing JR50 Rims

The design of the Japan Racing JR50 is based on a twin 5-spoke concept, where two spokes are arranged as a pair, creating a powerful, structured look. This results in a balanced ratio between open areas and solid elements, making the rim appear both modern and significantly more prominent.

Unlike classic rim-to-edge constructions, the spokes end before the outer edge of the rim, making way for a pronounced step lip. This stepped edge provides a clear visual separation between the spokes and the rim's lip, giving the JR50 its characteristic deep-dish look, which is highly sought after in the tuning scene.

A key feature of this model is the use of flow-forming technology. In this process, the rim barrel is compressed under pressure, achieving higher strength while reducing weight. Compared to conventional cast rims, the JR50 offers a noticeably better combination of stability and weight, which can positively impact handling and performance.

Depending on the combination of rim width and offset, the visual effect changes significantly. Particularly with wider variants, a pronounced concave structure is created, where the centre of the rim is visibly set inwards, while the outer edge remains emphasised. This combination of concave shape and step lip creates a particularly striking and three-dimensional look.

Available Sizes of the Japan Racing JR50 Rims

The Japan Racing JR50 rims are available in several diameters, covering a wide range of applications from sporty looks to individual vehicle customisation. Sizes available include 18 inches, 19 inches, and 20 inches, making the model suitable for both compact performance vehicles and larger saloons.

Dimensions such as 18 inches are often used in balanced setups where ride comfort and everyday usability are important. Larger variants like 19 inches or 20 inches, on the other hand, provide a much more prominent vehicle appearance and are often chosen for projects where design and overall impact are the priority.

The best size depends on the specific vehicle and the approved wheel and tyre dimensions.

Width of the JR50 Rims

In addition to diameter, rim width also plays a crucial role in selecting the right configuration. The Japan Racing JR50 is available in widths from 8J to 10J, offering ample scope for different vehicle setups.

Rim width influences, among other things, the tyre width that can be fitted and how the rim is positioned in the wheel arch. Narrower variants like 8J or 8.5J are often used in near-standard setups, while wider rims like 9.5J or 10J allow for a much sportier look and are often combined with wider tyres.

A special feature of the JR50 is the combination of rim width and step lip. As the width increases, the shape of the spokes changes significantly. With wider variants, they drop more towards the centre, creating a more pronounced concave look.

This combination of width, concave shape, and step lip makes the JR50 particularly interesting for so-called staggered wheel sets, where wider rims are used on the rear axle to achieve a more striking and wider vehicle appearance.

PCD and Vehicle Compatibility

The Japan Racing JR50 rims are available with a variety of different PCD (Pitch Circle Diameter) variants, allowing them to be used on many different vehicle platforms. Available PCDs include 5x100, 5x105, 5x108, 5x110, 5x112, 5x114.3, 5x115, 5x118, and 5x120.

This selection makes the JR50 rim suitable for both modern compact vehicles and more powerful saloons or custom-built projects. It is always crucial that the rim's PCD exactly matches the technical specifications of the respective vehicle.

A particular advantage of this model is that certain variants are offered as blank rims. In these cases, both the PCD and the centre bore can be individually adapted, allowing the JR50 to be configured for vehicles where standardised solutions are not always available. This enables a particularly precise and clean fitment without additional adjustments, especially for custom-tuned setups.

In addition to the PCD, the centre bore also plays an important role. The Japan Racing JR50 is available with different centre bore diameters depending on the variant, including 66.6 mm, 72.6 mm, and 74.1 mm. In many cases, a larger centre bore is used, which is precisely adapted to the vehicle's hub diameter using spigot rings.

Offset (ET)

In addition to diameter, width, and PCD, the offset (ET) is also important when selecting the right rim. The Japan Racing JR50 is available in an ET range of approximately ET20 to ET51, allowing for a variety of different vehicle configurations.

The offset describes the distance between the wheel centre and the mounting surface of the rim on the wheel hub. A smaller ET value causes the rim to sit further outwards, making the vehicle's track appear wider. A larger ET value, on the other hand, positions the wheel further inside the wheel arch.

Especially with a model like the JR50, which features a pronounced step lip, the choice of ET additionally influences the visual effect in the wheel arch. In combination with the rim width, this allows for targeted determination of how prominent the rim appears on the vehicle – from a balanced, near-standard position to a significantly more striking alignment.

Colours of the JR50 Rims

The Japan Racing JR50 rims are available in selected colour variants, allowing for different visual vehicle configurations. The range includes Black, Bronze, and Silver/Grey, enabling both subtle and more striking setups.

The Black variant is often used on modern vehicles as it offers a clean and timeless look that integrates well with the overall design. Bronze, on the other hand, is often chosen to create deliberate contrasts and give the vehicle a more individual, sporty touch.

Silver/Grey particularly emphasises the rim's structure and highlights the combination of spoke design and step lip. With this model, light reflections on the rim edge further enhance the three-dimensional effect.

The best colour choice primarily depends on the vehicle's design and the desired overall impression.

JR50 Rims with CH Approval

The Japan Racing JR50 rims offered here are supplied with a CH Supplement and a mounting kit. This allows the rims to be fitted to many vehicle models, as documentation is available for numerous applications that can be considered during the MFK (Motor Vehicle Inspection) test.

The mounting kit typically includes the necessary fasteners and spigot rings, ensuring the rims can be professionally mounted on the wheel hub.

As each rim variant can have different dimensions, widths, PCDs, and offsets, it is important to check which JR50 configuration is suitable for the respective vehicle before ordering. The 3D rim configurator can help find suitable variants for your vehicle.

Price and Delivery Time of the JR50 Rims

The price of the Japan Racing JR50 rims can vary depending on the dimensions, width, PCD, and finish. Larger variants such as 19 inches or 20 inches are generally more expensive than smaller versions, as they require more material and are often used on higher-performance vehicles.

Different rim widths or specific configurations can also influence the price. Therefore, it is worthwhile to compare the different JR50 variants and choose the right combination of dimensions and specifications.

Most variants of the JR50 rim have a delivery time of approximately 5 to 14 days, depending on the specific dimensions and finish.

Individual Check Before Ordering

Regardless of whether your vehicle is in standard condition or has modifications, an additional compatibility check before ordering may be advisable.
