The ADV.1 ADV05C in the Track Spec CS (Competition Spec) Series is a 3-piece forged wheel engineered around one directive: eliminate every gram that does not contribute to performance. The ADV05C is purpose-built around one priority: maximum concave depth. The spoke geometry places the face plane as deep within the barrel as structurally permissible, creating a pronounced shadow well at the center of the wheel that is visible from the front of the vehicle. The CS Series spoke cut-outs are placed to frame this concave chamber without breaking the uninterrupted depth impression. The CS Series designation marks ADV.1's highest-grade 3-piece construction — featuring FEA-optimized spoke geometry with standard integrated spoke cut-outs, forged 6061-T6 center discs paired with independently forged inner and outer barrel sections, titanium hardware as an available upgrade, and aggressive backpad pocketing on the inboard face. Every ADV05C CS Series set is custom-configured to your exact vehicle, fitment, and finish specification, and is hand-assembled at ADV.1's facility in Carson, California.
Recommended fitment process: ADV.1 builds each ADV05C CS Series set to your car's exact spec. Share your make, model, year, brake package, and target stance and our team confirms the optimal diameter, width, offset, and finish combination within 24 hours.
Need a different size or bolt pattern? The ADV05C CS Series is manufactured to order with no inventory constraints — any diameter, width, offset, or PCD can be specified at the time of order.

The CS Series sits at the peak of ADV.1's Track Spec 3-piece programme. Where the SL (Street Luxury) Series prioritizes a solid, heavyweight face aesthetic, the CS Series applies FEA (Finite Element Analysis) to every spoke geometry — identifying precise locations where wall material can be reduced without compromising structural load paths. The result is a spoke profile that is simultaneously stiffer in bending and lighter in absolute mass compared to a visually similar solid-spoke 3-piece. Standard spoke cut-outs, visible through the face openings, reinforce the competition heritage of the design. The ADV05C CS Series pairs this engineering discipline with ADV.1's full bespoke manufacturing infrastructure: any offset, any PCD, any finish, configured to one vehicle at one time.
Every finish is applied in-house at ADV.1's California facility. Color swatches and production-stage photography can be provided before final assembly and crating.
The ADV05C CS Series is engineered as a blank-slate fitment — offset, PCD, and hub bore are part of the order specification, not pre-set catalog values. ADV.1's Competition Spec geometry performs best on the following performance platforms:

The ADV05C CS Series carries no pre-drilled inventory. Every center disc is machined to the customer's specified PCD after forging, so the bolt pattern is a build parameter, not a catalog selection. Supported configurations include:
Lead time for any non-standard bolt-pattern build: 6–10 weeks from confirmed order and deposit.
| Series | Construction | Spoke Style | Best For |
|---|---|---|---|
| CS (Competition Spec) | 3-piece forged | FEA-optimized + spoke cut-outs | Maximum weight reduction, track-focused |
| SL (Street Luxury) | 3-piece forged | Solid polished face | Prestige aesthetic, street-oriented stance |
| M3-2PC | 2-piece forged | Monolithic center disc | Slimmer lip profile, lower overall weight |
| RS | 1-piece forged monoblock | Race-spec solid face | Lightest total mass, circuit use |
The ADV05C CS Series occupies the track-first, bespoke-spec 3-piece position — deepest concave available, maximum custom fitment, competition-grade FEA engineering.
If the ADV05C CS Series does not match your exact vision — different spoke count, different concave depth, alternative barrel profile — Hodoor offers a custom forged wheel manufacturing service. Send any reference image or sketch and we manufacture the wheel in any size, any colour, and any bolt pattern — fully forged from 6061-T6 aluminum to the same quality standards as ADV.1 catalogue production. Lead time is 3–6 weeks with worldwide delivery, and pricing is often competitive with premium European catalogue fitments. Contact us at [email protected] or via WhatsApp +44 7488 818747 for a quote.
What is the ADV.1 ADV05C Track Spec CS Series?
It is the Competition Spec 3-piece forged variant of the ADV05C design — manufactured from 6061-T6 aerospace-grade forged aluminum at ADV.1's facility in Carson, California. The CS designation means FEA-optimized spoke geometry, standard spoke cut-outs for weight reduction, optional titanium hardware, and aggressive backpad pocketing on the inboard face. Every set is custom-built to your exact PCD, offset, diameter, and finish.
What makes the CS Series different from the SL Series?
The CS (Competition Spec) Series adds FEA-guided spoke optimization and standard spoke cut-outs compared to the SL (Street Luxury) Series. This reduces unsprung mass further without sacrificing structural integrity — making the CS Series the preferred choice for track-day programmes, time-attack builds, and owners who prioritize performance over a solid-face aesthetic.
What cars does the ADV05C CS Series fit?
Any high-performance or luxury platform — common fitments include BMW M-series (M3, M4, M5, M8), Mercedes-AMG (C63, E63, GT, G63), Porsche (911, Cayenne, Panamera), Ferrari (458, 488, F8, 812), Lamborghini (Huracán, Aventador, Urus), McLaren (720S, 765LT), Audi RS-series, Chevrolet Corvette, and Rolls-Royce / Bentley. Every set is built to your exact PCD, offset, and brake clearance.
What sizes are available for the ADV05C CS Series?
Diameters from 13" to 24" and widths from 5J to 14.5J in any offset and bolt pattern. There is no pre-made inventory — ADV.1 forges each center disc to your specification after order confirmation. Custom dimensions beyond these ranges can also be accommodated on request.
Can I upgrade to titanium hardware on the ADV05C CS Series?
Yes. The standard hardware is stainless steel, and a titanium upgrade is available as an option at the time of order. Titanium fasteners typically reduce hardware weight by 30–50 grams per wheel — meaningful at the rim's outer circumference where rotational inertia is highest.
How long does delivery take?
Production lead time is 6–10 weeks from deposit payment, as every ADV05C CS Series set is forged, machined, finished, and assembled to your specification with no shelf inventory. Worldwide shipping from California adds 3–10 business days depending on destination. We provide in-progress build photos and ship notification with tracking before crating.
Are the ADV05C CS Series wheels available in center-lock configurations?
Yes. Center-lock builds are supported for Porsche 911 GT3 / GT3 RS / Turbo S, Lamborghini Aventador SVJ, Ferrari 488 Pista, and McLaren 720S / 765LT / Senna. Specify center-lock at the time of order and the hub adapter configuration is included in the build sheet.
The ADV05C CS Series ships regularly to all major performance-car markets worldwide. In Western Europe the strongest demand comes from the Netherlands, Switzerland, and the United Kingdom. In the Gulf, the UAE and Saudi Arabia are consistent markets for custom forged hardware. Mediterranean deliveries cover Cyprus, Turkey, and Greece. Every shipment leaves Hodoor with full export documentation and tracked, insured logistics — with direct liaison between you, our team, and ADV.1's California assembly facility.
