BC Forged RS42 Wheels
BC Forged RS42 — Forged Monoblock Performance Wheel
The BC Forged RS42 is a precision-engineered forged monoblock wheel, machined from a single billet of 6061-T6 aerospace-grade forged aluminum at BC Forged's dedicated 463,000 sq ft manufacturing facility in Taiwan. The RS42 features a bold multi-spoke design with a deep-set face and clean spoke geometry, combining an aggressive fitment profile with the structural rigidity inherent to single-piece forged construction. As part of BC Forged's RS Monoblock series — the brand's flagship one-piece forged lineup — the RS42 is engineered for drivers who demand both aesthetic impact and genuine performance engineering from their forged wheel.

Technical Specifications
- Manufacturing: CNC-machined forged monoblock — single billet, no welds, no joints
- Material: 6061-T6 aerospace-grade forged aluminum
- Design: Multi-spoke monoblock with deep-set face and aggressive spoke geometry
- Available Widths: 5.0J – 13.0J depending on diameter
- Weight advantage: Forged monoblock construction removes mass at both the spoke and barrel; a set of RS42 wheels is typically 20–30% lighter than a flow-formed or cast equivalent in the same diameter
- Finish options: Matte black, gloss black, brushed clear, brushed dark, brushed titanium, satin gunmetal, polished, custom colors and two-tone configurations
- Center cap: BC Forged branded forged aluminum cap, color-matched on request
- Hardware: Titanium bolt hardware available as upgrade
- Country of manufacture: Taiwan — BC Forged's 463,000 sq ft dedicated forging and finishing facility
- Build lead time: 6–10 weeks from confirmed order (made to order)
BC Forged controls every stage of production — from raw aluminum billet through forging press, CNC machining, and final finish — entirely within their own facility. This vertical integration ensures consistent metallurgical quality and dimensional accuracy across every wheel in a set.
Finish & Color Options
- Brushed: Brushed Clear, Brushed Dark, Brushed Titanium, Brushed Gold, Brushed Bronze
- Gloss: Gloss Black, Gloss White, Gloss Anthracite, custom gloss colors
- Matte: Matte Black, Matte Gunmetal, Matte Bronze, Matte Titanium, Matte Anthracite
- Satin: Satin Black, Satin Brushed Clear, Satin Royal Gold
- Premium upgrades: Two-tone center and barrel, polished spoke faces, exposed forged grain, custom color matching to factory or wrap codes
All finishes are applied and quality-checked at BC Forged's Taiwan facility before shipping. Color verification photos are provided before crating on request.
Manufacturing Process — Built in BC Forged's 463,000 sq ft Facility
BC Forged operates a fully integrated forging-to-finishing facility in Taiwan. The RS42 begins as a raw 6061-T6 aluminum billet: forged under several thousand tons of press force, then precision-machined on multi-axis CNC lathes and mills to final geometry. Spoke pocketing and back-pad relief cuts reduce weight without compromising structural integrity. Each wheel is individually inspected and balanced before being cleared for finishing and shipping. The facility handles its own anodizing, painting, powder coat, and polishing in-house — no outsourced finishing steps.

Frequently Asked Questions
What is the BC Forged RS42?
The RS42 is a single-piece forged monoblock wheel from BC Forged's RS Monoblock series — machined from 6061-T6 aerospace-grade forged aluminum at BC Forged's 463,000 sq ft Taiwan facility. It combines a multi-spoke architecture with deep concave face geometry and is produced entirely to-order in any size and finish.
What cars does the RS42 fit?
Any modern performance or luxury vehicle — common fitments include BMW M-series, Audi RS, Porsche, Mercedes-AMG, Toyota GR, Nissan GT-R, and Lexus performance platforms. Every set is built to your exact PCD, offset, and brake clearance.
What sizes does the RS42 come in?
BC Forged produces the RS42 in diameters from 15" to 24" and widths from 5.0J to 13.0J depending on diameter. Any offset and virtually any PCD are available since the wheel is made to order.
Is the BC Forged RS42 a forged wheel?
Yes — the RS42 is a true forged monoblock. BC Forged forges each wheel from raw 6061-T6 aluminum billet in their own press facility, then CNC-machines it to final geometry. It is not cast, flow-formed, or rotary-forged.
How long does delivery take?
Lead time is typically 6–10 weeks from confirmed order, as each RS42 set is produced to your specification. Worldwide shipping adds 3–10 business days depending on destination. Hodoor handles all export documentation and provides tracking from the moment the set ships.
Can I get the RS42 in a custom color or two-tone finish?
Yes. Brushed, gloss, matte, satin, polished, and two-tone center-and-barrel combinations are all standard options. BC Forged can also match factory paint codes or vehicle wrap codes — include the code with your order inquiry.

Wheel Care
- Clean with a pH-neutral wheel cleaner and a soft microfiber brush. Avoid alkaline or acid-based cleaners — they can damage brushed and satin finishes.
- Rinse with cool water before applying any product, and never spray onto hot rotors or hot wheel surfaces — let the brakes cool before washing.
- Apply a dedicated wheel sealant or ceramic coating every 3–4 months to protect against brake-dust etching and UV fading.
- Torque lug bolts to the vehicle manufacturer's specification and re-check after the first 50–100 km of driving.
- Inspect for kerb damage after any contact — forged wheels are impact-resistant, but any strike should be assessed by a wheel specialist before continued use.
