The Concept One CS-55 reframes what a five-spoke monoblock should look like. Where most single-piece designs flatten out at the rim, the CS-55 carries its spoke geometry deep into the barrel — available in standard, concave, and deep concave profiles so the same model fits everything from a subtle OEM-plus stance to a full show-build with maximum dish. The spoke faces are brushed for a two-texture contrast against the machined chrome lip, giving the wheel a premium hand-finished appearance without the lead time or cost of a fully bespoke multi-piece build. Each CS-55 is produced in the United States from forged-grade 6061-T6 aluminum, dimensioned to clear most factory brake setups in 20" and 22" diameters straight from the production run.
Recommended fitment note: The CS-55's concave and deep concave profiles create a pronounced dish that may require fender rolling or a mild pull on very aggressive offsets. Share your make, model, year, and brake package details and our team will advise the safest ET range for your build.
Need a different size or bolt pattern? Concept One manufactures custom orders on request — different diameters, widths, offsets, and bolt patterns outside the standard range can be specified at time of order. We also offer an AI Wheel Design Service if you want a custom concave spoke design inspired by the CS-55. Contact us at [email protected] and we will source the right fitment for you.
Construction detail: The CS-55 is machined from a single aluminum casting that is reinforced in key stress zones — spoke roots, window edges, and mounting face — while leaving material removed from low-load areas to keep the rotational mass competitive. The result is a wheel that handles road impact, not just looks, at the weight class you expect from a quality American forged design.
All finish work is applied at Concept One's US production facility. Sample swatches and color verification photos are available before production on custom-finish orders.
The CS-55's clean five-spoke geometry translates across a wide range of platforms. The directional design works particularly well on European sport sedans and luxury coupes, where the brushed-and-chrome two-tone scheme complements factory silver and dark exterior colors. Common fitments include:

The CS-55 is regularly ordered in bolt patterns beyond the standard 5x112 and 5x114.3 offerings. Common custom PCD requests include:
Custom bolt-pattern builds add 1–3 weeks to standard lead times. Contact us at [email protected] for a custom PCD quote.
| Model | Construction | Design | Best For |
|---|---|---|---|
| CS-55 | 1-piece monoblock | Five-spoke directional, brushed face | Sport sedans and luxury coupes — aggressive yet refined |
| CS-6 | 1-piece monoblock | Six-spoke modern design | Wider vehicle range, balanced spoke count |
| CSM-001 | 1-piece monoblock | Multi-spoke with machined lip | Maximum spoke density, luxury-SUV aesthetic |
| CSM-002 | 1-piece monoblock | Multi-spoke twin-split design | Twin-spoke drama on performance platforms |
| CF-006S | 3-piece forged | Custom six-spoke with step lip | Show builds, custom offsets, deepest concave |

The CS-55 sits in the Custom Series monoblock tier — five-spoke directional design, concave and deep concave profiles, brushed-and-chrome two-tone finish standard.
If the CS-55 profile isn't quite right for your build — different spoke count, a more extreme concave, or a fully bespoke spoke pattern — Hodoor offers a custom forged wheel manufacturing service. Send us any reference image or design concept, and we produce the wheel in any size, any colour, and any bolt pattern — fully forged from 6061-T6 aluminum to the same structural standards. Production takes 3–6 weeks with worldwide delivery. Contact us at [email protected] or via WhatsApp +44 7488 818747 for a quote.
What is the Concept One CS-55?
The CS-55 is a one-piece monoblock wheel from Concept One's Custom Series, built around a five-spoke directional design with brushed spoke faces and a machined chrome lip. It is available in standard, concave, and deep concave profiles in 20" and 22" diameters, with custom sizes on request. Made in the United States from 6061-T6 aluminum.
Is the CS-55 forged or cast?
The CS-55 is a cast-and-machined monoblock produced from forged-grade 6061-T6 aluminum. It is a one-piece construction — the spoke faces are machined and brushed after casting for the signature two-texture finish. For a fully forged three-piece build, Concept One's CF series (CF-006S, CF-001SX, CF-002SX, etc.) is the appropriate choice.
What cars does the CS-55 fit?
The CS-55 is a versatile fitment suited to European sport sedans (BMW, Mercedes-Benz, Audi), American performance platforms (Cadillac, Dodge, Ford Mustang), and Japanese luxury vehicles (Lexus, Infiniti). It has been installed on BMW 6 Series, Maserati Ghibli, and Infiniti Q50 builds, among many others. Bolt patterns 5x112 and 5x114.3 are standard; other PCDs are available on request.
What concave profiles are available?
In 20" diameter: Standard, Concave, and Deep Concave. In 22" diameter: Concave and Deep Concave. Profile determines how far the spoke face sits behind the outer lip — Deep Concave gives the most aggressive stepped appearance and is the most popular for show-oriented builds.
What finishes are available on the CS-55?
Standard production finishes include Matte Gunmetal with Brushed Chrome Lip and Silver Machined with Chrome Lip. Custom finishes — Gloss Black, Matte Black, Brushed Titanium, and custom two-tone combinations — are available on request with 1–2 week additional lead time for finish work.
How long does delivery take?
Standard production sizes (20×9, 20×10, 20×11, 22×9, 22×10.5) typically ship within 2–4 weeks. Custom sizes or custom finishes add 2–4 weeks to that. International shipping after dispatch is 3–10 business days depending on destination.
The CS-55 ships regularly to enthusiast markets across Europe, the Middle East, and Asia-Pacific. In Western Europe, strong demand comes from the Netherlands, Switzerland, and the United Kingdom, where the five-spoke directional design pairs naturally with the European sedan culture. In the Gulf, the UAE and Saudi Arabia are active markets for the CS-55's chrome-lip configuration. Mediterranean orders cover Cyprus, Turkey, and Greece. Every shipment leaves Hodoor with full export documentation and tracked, insured logistics.
