BC Forged RS43 15-23" Monoblock Forged Wheels

The BC Forged RS43 15-23" is a 1-Piece Forged Monoblock Wheel from the BC Forged RS Series, combining a clean multi-spoke design with lightweight-focused construction, deep concavity and highly customizable vehicle fitment.

The RS43 features a refined multi-spoke design with slim, evenly distributed spokes extending from the center toward the outer rim. The open spoke arrangement gives the wheel a technical and performance-oriented appearance while maintaining a clean look that works across a wide range of vehicle styles.

The wheel is manufactured from 6061-T6 Forged Aluminum, providing a strong and lightweight foundation for a performance wheel. BC Forged also lists the RS43 with JWL and VIA double certification, supporting its use on performance-focused road applications.

The RS43 offers an unusually broad range of sizes, with configurations from 15 through 23 inches for the JPM application. Width selection is also extensive, ranging from compact fitments to 13.0J on supported diameters. This allows the RS43 to be configured for standard applications, staggered setups and aggressive wide-body builds.

One of the defining characteristics of the RS43 is its Deep Concave Profile. The spokes flow inward toward the center of the wheel, creating greater visual depth and a more aggressive three-dimensional appearance.

The RS43 is custom built to order, allowing wheel specifications to be tailored to the individual vehicle. Available configurations include custom PCD, offset and vehicle-specific center bore, while multiple concavity profiles allow the wheel face to be matched to the selected fitment.

The wide range of available widths makes the RS43 particularly suitable for staggered and wide-body applications. The model has also been used in high-performance configurations such as an S2000 running 18x10.5 front and 18x11.5 rear wheels, as well as a Porsche Cayman using 19x9.5 front and 19x11.5 rear specifications.

The open multi-spoke design provides good visibility of the braking system and supports big brake applications. BC Forged specifications also list the RS43 as TPMS compatible, making it suitable for modern performance vehicles that retain factory tire-pressure monitoring systems.

For more demanding driving applications, optional anti-slip knurled bead seats can be specified to help improve tire stability under heavy acceleration, braking and cornering. Additional options include diamond-cut face finishing and center-lock configurations where applicable.

The broad diameter range gives the RS43 considerable flexibility. 15-inch configurations can suit compact and classic performance applications, while 18 and 19 inches provide a balanced performance proportion. Larger 20-23-inch configurations create a more substantial and aggressive appearance for modern performance cars and luxury vehicles.

With its combination of 1-Piece Forged Monoblock construction, 6061-T6 aluminum, multi-spoke styling, deep concavity, broad sizing and custom fitment, the BC Forged RS43 is suitable for sports cars, performance sedans, European performance vehicles, supercars and wide-body builds.

Wheel specifications should always be selected according to the individual vehicle. Wheel diameter, width, offset, PCD, center bore, brake clearance and tire specification should be confirmed before ordering.

For enthusiasts looking for a custom-built forged monoblock wheel with a clean multi-spoke design and aggressive concavity, the BC Forged RS43 offers a strong combination of lightweight-focused engineering, flexible sizing and vehicle-specific fitment.
