What is the Unibloc configuration, and how does it differ from Rohana's other RFG1 options?

Unibloc means the wheel is forged from a single piece of aluminum, prioritizing lightweight, motorsport-inspired performance over the multi-piece designs. The RFG1 is also available in Tandem (2-piece), Trinity (3-piece), and Carbon configurations, so Unibloc is the choice for those prioritizing weight savings and simplicity.

What sizes and widths are available?

The RFG1 is offered in diameters from 18" to 24" and widths ranging from 8.5" up to 13", with custom bolt patterns, offsets, and centerlock mounting all available since each wheel is built to order for your specific vehicle.

What finish options can I choose from?

Rohana offers a wide range of standard gloss, satin, and textured finishes (like gloss black, satin black, silver, and graphite) as well as premium finishes at an added cost, including 18K gold, candy red, chrome, high polish, and several other custom color options. A center cap cover and custom engraving are also available as upgrades.

How is each wheel actually manufactured?

Each RFG1 goes through a six-step process: initial design and engineering with Finite Element Analysis specific to your vehicle, lathe shaping of the wheel blank, CNC milling for precision detailing, engraving for a custom appearance, powder coating and clear coat finishing, and final assembly with quality control testing before it ships.

Will this wheel clear my big brake kit?

The RFG1 is designed with brake clearance factored into the engineering phase, and Rohana notes clearance for big brake kits as a standard feature, though it's worth confirming your exact caliper and rotor specs when placing your custom order.

Rohana Forged

Step 1 | Designing / Engineering:
- The design phase is a critical part of producing a forged wheel, laying the groundwork for all subsequent manufacturing steps. This stage requires meticulous attention to multiple factors to guarantee that the resulting product is aesthetically pleasing, effective, and secure. Every design is meticulously engineered to accommodate brake clearances and is subjected to a Finite Element Analysis (FEA) tailored to the specific vehicle.
Step 2 | Lathe:
- In the lathe operation, pre-formed cylindrical aluminum pieces known as wheel blanks are affixed to a lathe machine and spun at a rapid pace. A cutting instrument, directed by the machine, trims away material from the blanks, sculpting them into the intended wheel design. The accuracy of this lathe procedure is vital, as it impacts the wheel’s precision and stability. The outcome is a wheel characterized by exact dimensions, uniform thickness, and a polished finish.
Step 3 | CNC Milling:
- The CNC milling process is governed by a computerized program, employing precise algorithms to meticulously shape the wheel blank according to the detailed specifications provided in the design blueprint. This method boasts high precision and is capable of effortlessly creating wheels with complex and detailed geometries. The outcome of the CNC milling operation is a wheel characterized by its exact dimensions and a smooth surface, prepared for additional processing and finishing touches.
Step 4 | Engraving:
- The engraving step marks the culmination of Rohana’s forged wheel production process. In this phase, specialized tools are employed to inscribe or etch decorative patterns or logos onto the wheel’s surface. This technique imbues the wheel with a distinctive flair, crafting a bespoke appearance that distinguishes it from the rest.
Step 5 | Finishing:
- Following the removal of any residual debris from the engraving stage through sandblasting, the wheel undergoes powder coating and a clear coat is applied. This serves to shield it against corrosion and various environmental influences. Not only does this phase improve the wheel’s aesthetic appeal, but it also prolongs its durability and preserves its quality.
Step 6 | Assembly & Quality Control:
- In the assembly phase, the separate parts of the wheel, including the face, inner barrel, and outer barrel, are assembled and tightly joined to form a unified, finished wheel. Upon completion of the assembly, the wheel undergoes a series of tests and checks to verify that it conforms to the necessary standards and specifications.

Unibloc

The Unibloc option is crafted from a single piece of aluminum, employing a lightweight and performance-focused approach. Manufactured to include only the essentials, it features motorsport-inspired, sleek designs without any unnecessary bulk, making it the ultimate performance wheel.

Additional Information

The Bulletproof Automotive website contains many thousands of products purchased in multiple different currencies. All of the prices are entered manually and accurately at the time of entry. Due to the consistently fluctuating international exchange rates, at times prices may not be able to be honored at their original intended rate. We apologize for any inconvenience this may cause, unfortunately our website is unable to compensate dynamically for what can at times be volatile changes in the cost of items due to currency values fluctuating, changes in prices from suppliers, changes in shipping and import duties, and other factors. Rest assured that any order you place on line will be at zero risk to you in this area. If in the event your order cannot be fulfilled at the original intended website price we will offer you a 100% refund, no questions asked. We will continue to do our best to maintain updated prices and we will always continue to offer our price match guarantees as well to ensure our prices are always the best for you. In short, prices may change without notice. It is always advised to give us a call prior to placing your order online to confirm availability and to confirm current pricing.

Shipping Policy

Items that are in stock in the US, either at Bulletproof’s warehouse or at a supplier’s warehouse, are generally delivered within 7-10 days. Special order items from overseas take considerably longer. As a courtesy Bulletproof offers delivery estimates to our customers which take into consideration manufacturer availability and shipping schedule. These estimates represent our best guess based on previous orders from the manufacturer and do not in any way imply a guaranteed delivery window. Many manufacturers work in a “just in time” inventory system and often take 2-20+ weeks to produce an item once an order is submitted. All deliverable items are then sent to our Japanese warehouse. Bulletproof ships a minimum of one full ocean freight container every month from Japan, oftentimes more than one a month. Ocean freight takes an average of 4 weeks. Typically it breaks down to one week in Japan for paperwork and customs, two weeks by boat and one week in US customs/clearance. Due to the wide number of variables between manufacturer and shipping schedules, delivery estimates are simply just that – estimates. We attempt to estimate conservatively and we usually deliver faster than our estimates suggest. It is not Bulletproof’s policy to guarantee delivery time of any special order item, this is impossible for us to do. By ordering you acknowledge that there is no required delivery ETA and an order may not be canceled or altered due to manufacturing or shipping delays, all ETA’s are provided as a best guess only. Please review the full Terms & Conditions here.

BP Pricing Difference

We do pricing a little differently on our JDM brands and we believe in making things simple and clear. No hidden fees or surcharges. Every price you see includes the shipping cost to our office in Los Angeles, California and all the associated taxes/duties/fees for bringing the products into the US. The only shipping you ever pay is from our facility in the US to your location. Be wary of resellers that don’t include the cost of international shipping in their pricing on JDM parts. While we believe we’ll always have the lowest all-in price on JDM products, we offer a price match guarantee for all authentic parts purchased from authorized dealers as well. For many international customers, it’s much more affordable to ship from the USA than from Japan directly, as the air freight and ocean freight costs are typically much less. However, for customers looking to ship directly from Japan outside of North America, or domestically in Japan, we can provide pricing specifically for that scenario. Please do not hesitate to contact us with any pricing questions or concerns. Please email us at sales@bulletproofautomotive.com with any inquiries.
