The Kia Stinger has always been the sleeper of the segment — a genuinely quick, well-balanced GT that most people underestimate until they see the twin-turbo badge or hear the exhaust note. What it has never had much of is presence out back. Vicrez’s Centa VR2 Rear Diffuser (SKU vz104135) for 2020–2024 Stinger models is built to fix exactly that, adding a real diffuser profile under the rear bumper without touching the car’s factory exhaust or bumper geometry.
Key Takeaways
- Purpose-built fitment. Vicrez engineers the Centa VR2 from the Stinger’s own 3D scan CAD data and CNC-cuts every unit, so it lines up with the factory bumper without trimming or forcing.
- Functional, not just cosmetic. The five-fin diffuser profile is designed to manage airflow off the rear underbody, working toward reduced drag and added rear downforce rather than just looking the part.
- Made in the USA. Durable ABS plastic construction with a gloss black finish as the base look, built to handle daily-driver use.
- Fully customizable. Eight color edge-trim options and finishes ranging from matte black to gloss and forged carbon fiber vinyl let buyers match their own Stinger’s color and style.
A Rear End That Finally Matches the Rest of the Car
Stock, the Stinger’s rear bumper is clean but plain — there’s a lot of unused visual real estate between the quad exhaust tips. The Centa VR2 fills that space with a five-blade diffuser insert finished in gloss black, with an optional color edge trim (Vicrez offers black, blue, green, orange, purple, red, white, or yellow) that traces the outline of each fin. On a car finished in a bold color like the red Stinger GT shown here, a matching red edge trim ties the whole rear fascia together instead of just bolting on a generic black add-on.
The design also works around the factory quad-tip exhaust rather than against it, so there’s no cutting, trimming, or exhaust-tip swap required to get a finished, factory-style look.
Engineered Fitment, Not a Universal Bolt-On
Vicrez builds its aero parts from actual 3D scan geometry of the vehicle, then CNC-machines each piece to that CAD data. For a diffuser, that distinction matters more than it might seem — a universal or loosely-fitted diffuser tends to leave visible gaps at the bumper line or need trimming to sit flush. The Centa VR2 is cut specifically for the Stinger’s rear bumper contour, and it ships with the hardware needed for installation.
Vicrez’s own installation notes are straightforward on this point: the process is simple enough for an experienced DIYer, but professional installation is recommended for anyone not comfortable working underneath the rear bumper, and test-fitting before any paint or vinyl work is applied is worth the extra step.
Built to Spec, Not Just Off the Shelf
The base Centa VR2 ships in matte black ABS plastic, but the ordering options are where this part gets interesting for anyone building a specific look. Beyond the eight color edge-trim choices, the surface finish itself can be upgraded to gloss black vinyl, matte black vinyl, dry or gloss carbon fiber vinyl, satin black, carbon flash metallic, forged carbon fiber, satin black ice, or urban camo — effectively letting a buyer spec the diffuser to match a wrap, a wheel finish, or an existing carbon fiber trim package elsewhere on the car.
Featured Product
Pricing starts at $292.66 for the standard matte black finish with no color edge trim; color edge trim adds $44.99, and premium vinyl finishes range from about $119 to roughly $199 depending on the material.
The Bottom Line
For a Stinger owner who already likes the car’s performance but wants the rear end to look as serious as the drivetrain feels, the Centa VR2 is a bolt-on way to get there — CAD-matched fitment, a genuine diffuser shape instead of a flat cosmetic panel, and enough finish options to match almost any build.
