KCLAB'S RIG

The base architecture is straightforward: aluminum extrusion, angle brackets, and CNC mounting plates. That is part of the appeal. Extrusion gives excellent value for money, but the difference between an ordinary frame and a refined one is in the finishing work, the mounting logic, and the tolerances of the custom pieces that tie everything together.

This build uses 40160 profile in anodized sandblasted silver rather than the more common black finish. It is less forgiving, but it gives the rig a cleaner industrial character. Karl also helped machine a number of custom parts, which made it possible to solve fitment and integration problems properly instead of working around them.

The wheelbase is a Simucube 3 Pro. There are lower-cost systems that get very close in outright performance, but this was a deliberate choice for refinement, consistency, and ownership confidence. On the pedal side, the Simucube Active Brake is one of the pieces that genuinely changes how the car feels to drive, especially once you start relying on brake feedback rather than visual cues alone.

The rig also runs several wheel options, including a modified Porsche road-car style wheel, a VPG Cup, and a custom RB16 V2. The DDU is a silver CNC-housed display built by a hobbyist maker around a 7.8-inch VCSCORE panel, mounted on a custom bracket designed to work cleanly with the extension shaft and motion clearances.

The motion platform uses Wufen Tech electric actuators. Beyond a certain point, motion systems tend to flatten out in value, so this was one area where the budget was kept focused rather than chased for the sake of bigger numbers. The more interesting part is what sits underneath it.

Most isolation products are too soft for a rig like this once motion loads and transducers enter the picture, so this setup uses custom constrained-layer isolators built around rubber, butyl, and stainless layers housed in CNC aluminum. The result is a rig that can move aggressively without sending the same energy through the room.

The seat is a Ferrari 296-inspired track shell paired with Sabelt sim belts and Qubic Systems belt tensioners. The monitor package is a triple Kuycon P32K setup chosen not only for resolution and refresh rate, but because it fits the silver language of the rest of the build surprisingly well.

From the custom carpet to the button boxes, CNC LED flag light, titanium fasteners, aluminum keyboard tray, and hidden cable-management compartment, the philosophy stays the same: keep the rig visually clean, mechanically honest, and coherent from every angle. None of those parts changes lap time on its own, but together they are what make the cockpit feel complete.
