The Concept One CSM-5 is a five-spoke monoblock wheel from the CSM Custom Series — the sport-concave model in a lineup defined by its clean spoke count and machined lip finish. Built in the United States from 6061-T6 aerospace-grade aluminum, the CSM-5 delivers a concave spoke face, multiple available widths, and a premium single-piece construction suited to performance coupes, sports cars, and luxury-sport SUVs. Single-piece construction eliminates the hardware joints and lead times of a multi-piece build, keeping the CSM-5 accessible across a broad range of common PCD patterns and widths.
Recommended fitment note: The CSM-5 is available in concave and standard profiles. Share your make, model, year, and brake package and our team will advise on optimal diameter, width, and offset within 24 hours.
Need a different size or bolt pattern? The CSM-5 is available in any common PCD and in widths from 5J to 14.5J. We also offer an AI Wheel Design Service if you want a custom spoke pattern or finish concept designed before committing to an order. Contact [email protected] and we will source the right fitment for you.
Construction note: The CSM-5's single-piece architecture machined from forged-grade 6061-T6 aluminum delivers a premium lip finish without the assembly hardware of a split three-piece design. The spoke faces are concave-profiled to deepen the appearance of the barrel, while the machined outer lip — available in chrome, brushed, or painted finishes — gives the wheel a two-texture look consistent across the CSM series. For builds requiring custom barrel depth beyond what the monoblock format allows, the Concept One CF series provides a full three-piece alternative in matching spoke configurations.
All finish work is applied at Concept One's US production facility. Finish swatch photos available on request.
The CSM-5 five-spoke monoblock has been fitted to a wide range of performance and luxury platforms:

The CSM-5 is produced in standard and custom bolt patterns:
| Model / Series | Construction | Design | Best For |
|---|---|---|---|
| CSM-5 | 1-piece monoblock | Five-spoke, concave face | Performance coupes, Porsche/Mustang/BMW builds |
| CS-55 | 1-piece monoblock | Five-spoke directional | Sport sedans — concave and deep concave profiles |
| CS-6 | 1-piece monoblock | Six-spoke clean geometry | All-around luxury and sport fitments |
| CSM-001 | 1-piece monoblock | Multi-spoke machined lip | Luxury SUVs — maximum spoke density |
| CF Series (CF-001 to CF-007) | 3-Piece Forged | Custom spoke designs | Show builds — custom depth and hardware |
| RS-55 Executive Edition | 3-Piece Forged | Classic five-spoke | Premium builds — step-lip and deep-lip |
The CSM-5 sits in the CSM Custom Series monoblock tier — a sport-concave five-spoke design optimised for performance coupe platforms where spoke count and concave depth matter more than three-piece customisation.
If the CSM-5 is not the right match — a different spoke geometry, more extreme concave depth, or a fully bespoke design — Hodoor offers a custom forged wheel manufacturing service. Send us any reference image or design sketch and we manufacture the wheel in any size, colour, and bolt pattern — fully forged from 6061-T6 aluminum. You can also use our AI Wheel Design Service to visualise your concept before production begins. Contact [email protected] or WhatsApp +44 7488 818747.
What is the Concept One CSM-5?
The CSM-5 is a five-spoke monoblock wheel from the Concept One CSM Custom Series — a sport-concave design produced in the United States from 6061-T6 aerospace-grade aluminum. It has been fitted to Porsche 911, Ford Mustang, BMW M3/M4, and Chevrolet Camaro platforms and is available in 18" to 24" diameters with standard and concave profiles.
Is the CSM-5 forged or cast?
The CSM-5 is a cast-and-machined monoblock produced from forged-grade 6061-T6 aluminum. The single-piece format eliminates hardware joints, simplifies installation, and delivers a premium brushed-and-machined finish. For a fully forged 3-piece build with custom barrel depth, Concept One's CF series is the appropriate choice.
What spoke design does the CSM-5 have?
The CSM-5 features a five-spoke concave face design — the "5" in CSM-5 refers to the five-spoke layout. The spoke faces are concave-profiled to create a deep visual dish effect, and the outer lip is machined to a bright finish that contrasts with the painted or brushed spoke surfaces.
What cars does the CSM-5 fit?
The CSM-5 supports any 5-lug vehicle with standard bolt patterns in 5×112, 5×114.3, 5×120, and 5×130. Featured fitments include Porsche 911, Ford Mustang, BMW M3/M4, Chevrolet Camaro, Audi RS4/RS5, and Nissan GT-R. Custom PCDs available on request.
What finishes are available for the CSM-5?
Standard offerings include Matte Black, Gloss Black with Machined Lip, Matte Gunmetal, Brushed Silver, and Silver Machined with Chrome Lip. Custom finishes and two-tone combinations are available on request — contact [email protected] for swatches.
How long does delivery take?
Stocked configurations ship within 3–7 business days. Custom offset, PCD, or finish requests take 3–6 weeks. International shipping adds 3–10 business days. Fully insured and tracked door-to-door delivery included.
The Concept One CSM-5 ships regularly to performance and enthusiast markets across Europe, the Middle East, and Asia-Pacific. Strong demand in Western Europe comes from the Netherlands, Switzerland, and the United Kingdom, where Porsche and BMW ownership is high and five-spoke monoblock designs are a popular fitment. In the Gulf, the UAE and Saudi Arabia are consistent markets for US-forged wheels on Mustang and GT-R platforms. Mediterranean deliveries cover Cyprus, Turkey, and Greece. Every shipment leaves Hodoor with full export documentation and tracked, insured logistics.
