The Snapshot: High-Performance Hardware Meets Modular Customization
Pokornyi Engineering isn't just a store; it’s a technical hub for the global sim racing community. Specializing in ultra-realistic, professional-grade steering wheels—from the TGR-H Hypercar to the LMP PRO V2—they provide the "blueprints" and the "bricks" for enthusiasts to build their own elite racing rigs.
While their digital design files gave users the plan, the physical components (PCBs, CNC-cut carbon fiber, and LED modules) required a more structured shopping experience. Instead of forcing customers to hunt for individual screws and plates across multiple pages, Pokornyi Engineering sought to provide a "one-stop" assembly kit. By implementing a guided, modular bundling strategy, they transformed a complex technical parts list into an engaging, user-friendly project builder.
The Starting Line: Context & Opportunity
As a leader in the DIY sim racing niche, Pokornyi Engineering faced a unique e-commerce challenge: Technical Friction.
A professional steering wheel build requires dozens of specific parts—buttons, backplates, connector mounts, and stickers. For a customer, the risk of forgetting a single M12 connector or a specific PCB could stall a weeks-long project. For the brand, selling these as isolated line items led to lower order values and a fragmented customer journey.
The opportunity was to create a "GTB PRO DIY Kit" experience. By transitioning from a parts-catalog model to a kit-based architecture, Pokornyi Engineering could ensure customers had everything they needed for a successful build while significantly increasing the revenue generated per session.
The Solution & Execution: The "Build Your Own Box" Framework
Using the Kefi Commerce suite, Pokornyi Engineering launched a sophisticated Build Your Own Box (BYOB) experience tailored to the precision needs of engineers and gamers alike.
1. The Interactive DIY Kit Builder
Pokornyi implemented a structured, multi-step bundle builder for their flagship kits. This allowed users to:
- Select the Core: Start with the primary PCB and Controller boards.
- Customize Aesthetics: Choose specific front panel decals, button stickers, and LED "brows."
- Add Structural Components: Pick the exact CNC-cut aluminum mounts and carbon fiber plates required for the specific wheel model.

2. Frictionless Technical Selection
The bundle was designed to eliminate "choice paralysis." By grouping compatible parts into a single flow, the store acted as a digital consultant, guiding the user through a logical assembly sequence. This ensured that every "Build Your Own" box was technically complete and ready for assembly upon arrival.
Implementation Highlights:
- Project-Based Bundling: Bundles were curated around specific steering wheel models (like the GTB PRO), making the upsell feel like a helpful service rather than a sales pitch.
- Visual Validation: Using Kefi’s sleek interface, customers could see their kit coming together, mirroring the satisfaction of the physical build process.
- Incentivized Completeness: Encouraging users to "complete the set" helped move smaller accessories and spare parts that might otherwise be overlooked.
The Outcome: $25k in Dedicated Growth
The move toward modular, project-based bundling delivered high-impact results within a 60-day window:
- Significant Revenue Contribution: The "Build Your Own" strategy generated $25,117 in new bundle revenue, proving that sim racers prefer curated kits over individual part hunting.
- Consistent Order Velocity: With 1,592 orders processed, the system demonstrated its ability to handle steady, high-intent traffic without technical overhead.
- Enhanced Brand Authority: By providing a guided kit-building experience, Pokornyi Engineering solidified its reputation as a premium, user-centric provider of DIY hardware.
The data is clear: by giving customers the tools to build their own experience, Pokornyi Engineering didn't just sell parts—they sold a completed project, maximizing both customer satisfaction and store profitability.
