Japan Racing SL04

Buying Guide for Japan Racing SL04 Rims

The Japan Racing SL04 rims belong to the so-called Super Light Series and are specially developed for drivers who, in addition to appearance, also value low weight and precise handling and are looking for a combination of functional motorsport design and everyday usability. Through the combination of classic design and modern manufacturing technology, this model is primarily aimed at performance-oriented vehicle configurations.

The SL04 rim is available in various diameters and widths and is suitable for both sporty road vehicles and performance-oriented conversions. 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 SL04 Rims

The design of the Japan Racing SL04 is based on a classic 6-spoke concept, which is oriented towards functional motorsport rims. The clearly shaped spokes extend directly to the outer edge of the rim, creating a rim-to-edge construction, which makes the rim appear visually larger while creating an open, technical look.

In contrast to many purely visually oriented tuning rims, the focus of the SL04 rim is clearly on performance. The open design can help to make the brake system more visible and at the same time support airflow in the brake area, additionally offering benefits in cooling the brake system, which is particularly relevant for sporty driving or track use.

A key feature of this model is the use of flow-forming technology. In this manufacturing process, the rim ring is compacted under pressure, which allows for high material strength to be achieved while simultaneously reducing weight. This reduces unsprung mass, which can have a positive effect on acceleration, braking performance, and driving dynamics.

Depending on the combination of rim width and offset, the SL04 can have different profile shapes. While narrower variants appear rather flat, wider versions have a more pronounced, technically oriented concave shape, which further emphasises the sporty character of the vehicle.

Available Sizes of the Japan Racing SL04 Rims

The Japan Racing SL04 rims are available in several diameters, covering a compact but clearly performance-oriented range of applications. Sizes available are 15 inches, 18 inches, and 19 inches, making the model suitable for both lighter vehicle configurations and sportier road vehicles.

Smaller diameters such as 15 inches are often used on lighter vehicles or in setups where low weight and direct handling characteristics are paramount. Larger variants such as 18 inches or 19 inches, on the other hand, offer more presence and are often used on vehicles where a sporty appearance is desired in addition to driving dynamics.

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

Width of the SL04 Rims

In addition to diameter, rim width also plays an important role in selecting the right configuration. The Japan Racing SL04 is available in widths from 7J to 10J, offering sufficient scope for various sporty vehicle setups.

Narrower variants such as 7J or 8J are often suitable for near-standard configurations and allow for a balanced combination of driving comfort, stability, and low weight. Wider rims such as 8.5J, 9J, 9.5J, or 10J, on the other hand, are often used on sportier vehicles or for performance-oriented conversions.

As the width increases, the visual impact of the rim also changes. Particularly with wider variants, the Japan Racing SL04 develops a more pronounced, technically oriented concave shape, making the rim appear significantly deeper and further enhancing the sporty character of the vehicle.

PCD and Vehicle Compatibility

The Japan Racing SL04 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 4x100, 4x108, 4x110, 4x114.3, 5x100, 5x105, 5x108, 5x110, 5x112, 5x114.3, 5x115, 5x118, and 5x120.

This selection makes the SL04 rim suitable for both compact vehicles and sporty saloons or performance-oriented vehicle configurations. It is always crucial that the rim's PCD exactly matches the technical specifications of the respective vehicle.

In addition to the PCD, the Center Bore (hub bore) also plays an important role. The Japan Racing SL04 is available with different center bore diameters depending on the variant, including 66.6 mm, 72.6 mm, and 74.1 mm. In most cases, a larger center 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) also plays an important role in selecting the right rim. The Japan Racing SL04 is available in an ET range of approximately ET15 to ET51, allowing for different vehicle setups.

The offset describes the distance between the wheel's centre line and the mounting surface of the rim on the wheel hub. A smaller ET number causes the rim to sit further outwards, while a larger ET number positions the wheel further inside the wheel arch.

Choosing the correct ET is crucial to ensure sufficient clearance from the brake system, suspension, and bodywork. At the same time, the offset also influences the wheel's position within the wheel arch and thus the visual appearance of the vehicle.

Colours of the Japan Racing SL04 Rims

The Japan Racing SL04 rims are available in several colour variants, offering suitable options for both classic and more eye-catching vehicle configurations. The range includes Black, Bronze, Gold, Multicolor, and Silver/Grey, among others.

Darker variants such as Black or Bronze are often chosen for sporty vehicles as they create a contrasting and dynamic look, emphasising the performance-oriented character of the rim. Lighter colours such as Silver or Silver/Grey, on the other hand, more strongly highlight the rim's shape and make the 6-spoke design particularly clear.

More striking variants such as Gold or Multicolor are also frequently used in the tuning and motorsport scene when a stronger visual contrast is desired. The best colour choice primarily depends on the vehicle's design and the desired visual effect.

To get a better impression of the different colour variants, it can be helpful to look at real vehicle images. In our Vehicle Gallery, you will find numerous examples of how different SL04 rims look on various vehicles.

SL04 Rims with CH Approval

The Japan Racing SL04 rims offered here are supplied with a CH Approval and a fitting kit. This allows the rims to be fitted to many vehicle models, as corresponding documentation is available for numerous applications, which can be considered during the MFK (Motor Vehicle Inspection) test.

The fitting kit typically includes the necessary fastening elements and spigot rings, so that the rims can be professionally mounted on the wheel hub.

Since each rim variant can have different dimensions, widths, PCDs, and offsets, it should be checked before ordering which SL04 configuration is suitable for the respective vehicle. The 3D Rim Configurator can help you find suitable variants for your vehicle.

Price and Delivery Time of the SL04 Rims

The price of the Japan Racing SL04 rims can vary depending on the dimension, width, PCD, and finish. Larger variants such as SL04 18-inch or SL04 19-inch rims are generally more expensive than smaller versions, as they require more material and are often used on higher-performance vehicles.

Different rim widths or special finishes can also influence the price. Therefore, it is worthwhile to compare the different SL04 configurations and choose the right combination of dimensions and features.

Most variants of the SL04 rim have a delivery time of approximately 5 to 14 days, depending on the specific dimension 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.

If there are any uncertainties regarding ET, width, PCD, or MFK-relevant aspects, an individual check can be carried out in direct coordination with our team.

You can contact us quickly via WhatsApp and send us your vehicle model and the desired SL04 rim configuration. This allows technical and legal questions to be clarified before ordering, making the purchasing decision more transparent and secure.
