Most shops bolt radar components wherever they fit and call it a stealth install. At Saint Nordic Custom Autoworks in Spring Lake Park, we do something different. Every custom radar installation we build starts with a 3D scan of your vehicle, moves through CAD modeling and custom component design, and ends with FDM-printed, acrylic-finished mounts that are built specifically for your car. The result isn't close to factory — it is factory.
Why Stealth Installation Matters
A radar detector sitting on your windshield announces itself to everyone around you — law enforcement included. Many states have RDD (radar detector detector) equipment that can identify a detector's electronic emissions from outside the vehicle. And in Minnesota, windshield-mounted accessories can be cited under the state's obstruction law with fines up to $300.
A truly stealth system changes the equation entirely. Antennas live inside your bumpers. Transponders mount in grille openings and other vehicle-dependent locations that provide the necessary field of view without being visible. Wiring routes behind door sills and through factory harness paths. The display can be integrated into a custom-fabricated enclosure finished with smoked acrylic — completely hidden in plain sight, blending into your interior as if it was always there. Someone looking at your vehicle from any angle, including law enforcement running RDD equipment, sees nothing out of the ordinary.
But stealth installation done right requires more than hiding components wherever they happen to fit. It requires components that are built for your specific vehicle — and that's exactly what separates what we do at Saint Nordic from every other shop in the Twin Cities.
Our Process — From Scan to Street
Every stealth radar installation at Saint Nordic goes through the same process. No universal brackets. No foam tape and zip ties. No improvised solutions. Here's exactly how we build these systems.
We begin by 3D scanning the specific mounting areas of your vehicle — bumper cavities, grille openings, and any interior location where a display enclosure needs to integrate. This isn't measuring with a tape. It's capturing the exact geometry of your vehicle's surfaces in three-dimensional space — every curve, every draft angle, every mounting boss — with millimeter-level accuracy. The scan becomes the foundation everything else is built from.
The 3D scan is imported into CAD software where we design the mounting components for this specific vehicle and this specific system. We're designing brackets, housings, and mounts that account for the radar antenna's coverage angle, the laser transponder's required field of view, the available clearance behind the bumper, and the structural mounting points available in that specific location. Every component is modeled to fit perfectly — not approximately.
The CAD models are printed using FDM (Fused Deposition Modeling) — the same additive manufacturing process used in aerospace and automotive prototyping. We print in materials selected for the environment each component will live in: heat-resistant for engine bay and bumper locations, flexible where vibration tolerance is needed, rigid where structural mounting is required. The printed components fit the vehicle exactly as designed because they were designed from that vehicle's exact geometry.
Printed component mounts are finished with acrylic coatings that eliminate the visible layer lines of FDM printing and produce a smooth, factory-quality surface. Color-matched to your vehicle's surfaces as appropriate, the finished components are visually indistinguishable from OEM plastic trim. The R9W display — which lives permanently in the cabin — can be integrated into a custom-fabricated stealth enclosure finished with smoked acrylic. The display sits behind the smoked panel, completely hidden when off and perfectly legible when active. From the driver's seat it reads cleanly. From outside the vehicle it's invisible. This is the same approach we take to every component of the build — if it can be made to disappear, we make it disappear.
Custom mounts in hand, we install the complete system — routing wiring through factory harness paths, mounting antennas and transponders in their designed positions, integrating the controller in a hidden location, and calibrating the system for your specific vehicle's geometry. We verify detection angles, confirm all components are communicating correctly, and tune the system before you leave the shop. The installation is complete when it performs exactly as it should — not before.
The geometry of a radar antenna's mounting position directly affects detection range and angular coverage. A component installed at the wrong angle or in a location that creates signal obstruction performs significantly below its rated capability. Our custom-designed mounts position every component at the optimal angle for maximum performance — not wherever it happened to fit. You get the full capability of the system because the installation was engineered to deliver it.
The System — Uniden R9W
The platform we build these stealth installations around is the Uniden R9W — the most capable custom-installed radar and laser defense system available. The R9W was designed from the ground up for professional installation, with modular components that adapt to a wide range of vehicle configurations. Paired with our custom-fabricated mounting system, it delivers the full performance of the R9W with a completely invisible footprint.
Quad Blackfin® DSPs, dedicated front and rear radar antennas, up to 6 laser transponders (3 front, 2–3 rear depending on vehicle application), Wi-Fi OTA updates, GPS, Bluetooth, and R/TACH app integration. Every component hidden inside your vehicle with custom-fabricated mounts designed specifically for your build.
Laser jamming devices are illegal in Minnesota under MN Statute 169.14. If laser transponders are included in your R9W installation, they will leave our facility with the laser functionality disabled. We will not enable or activate laser jamming capability on any vehicle that will be operated in Minnesota. Radar detection remains legal for passenger vehicles in Minnesota. It is your responsibility to know and comply with the laws of your state and any state you travel through.
This Is Not Available Everywhere
The combination of 3D scanning, custom CAD design, FDM printing, and acrylic finishing applied to a radar installation is not something most shops can offer — or have any interest in figuring out. It requires investment in equipment, software, materials, and the expertise to use all of them at a level that produces a factory-quality result.
At Saint Nordic, this capability exists because we built it. The same technology and workflow we apply to radar installations is the same foundation we use for other custom fabrication work in the shop. When you bring a vehicle to us for an R9W installation, you're getting a build that was engineered specifically for that vehicle — not adapted from something that worked on someone else's car.
No two R9W installations we do are identical — because no two vehicles are identical. The scan, the CAD model, the printed components, and the installation plan are all specific to your vehicle. If you want to discuss what an R9W build looks like for your specific car, truck, or SUV, call us at 763-260-1491 or stop by the shop at 7703 Central Ave NE, Spring Lake Park.
