The Porsche 911 GT3 RS (992) is engineered for the track. Lightweight construction, active aerodynamics, and an uncompromising suspension setup make it one of the most radical street-legal GT cars in its class. Every detail serves one purpose: maximum performance.
For TIKT Performance, this exceptional foundation marks the starting point for the next stage of development. With our custom-engineered carbon fiber aerodynamic components, we build on the distinctive design language of the GT3 RS, taking its lines a step further while combining functional design with the highest standards of manufacturing precision.
Our ambition: to create an evolution that doesn’t feel like an aftermarket addition, but like an integral part of the vehicle itself. Engineered down to the finest detail. No compromises in materials, craftsmanship, or fitment.
14-piece construction. Full carbon. Measurably more front downforce in direct comparison with commercially available competition kits.
The front splitter is the aerodynamic centerpiece of every serious GT3 RS kit. We redesigned it from the ground up: 14 individual full-carbon segments, precisely joined together, with a completely smooth, enclosed underbody that channels the airflow cleanly toward the diffuser. All mounting points are recessed — no bolt heads disrupting the airflow and no visual interruptions on the component that defines the character of the car at first glance.
The result is measurable in direct comparison: noticeably more front downforce than commercially available competition kits in this class. More pressure on the front axle means greater stability under braking, greater precision at turn-in and more confidence through fast direction changes — exactly where the standard RS otherwise begins to feel light first.
Our steel-cable bracing completes the setup: uncompromisingly rigid under downward load for maximum transfer of aerodynamic forces into the body, while offering controlled upward flexibility — so curbs and pit-lane entrances are no longer a risk.
Multi-stage configuration. Full carbon. The part of the kit that ultimately pins down the front axle.
The canards intercept the airflow exactly where it would otherwise pass unused around the outer edge of the bumper and alongside the front wheel. Each wing element generates its own tip vortex, serving two purposes simultaneously: it pushes the front end down and shields the wheel arch from lateral pressure build-up.
The elements are staggered because a single large surface separates airflow earlier than several smaller ones. Their height and angle are positioned relative to one another so that each operates in the clean airflow of the element above — more downforce with a smaller increase in drag.
Manufactured entirely from full carbon and developed together with the splitter as a single system, rather than added as an accessory. The transition to the bumper edge is seamless, with no gaps and no silicone bead.
Full carbon. Designed around the floor fences. Visually indistinguishable from the factory design — except for the material.
The side skirts are not merely a visual add-on, but a functional aerodynamic component. They are deliberately positioned slightly higher so that the factory floor fences remain fully exposed and can perform their intended function: lateral airflow separation, clean underbody airflow through the center, and uninterrupted suction toward the diffuser.
Construction: continuous full carbon with an aerodynamically optimized profile, precisely aligned with the load paths of the RS. The design and finish are matched so precisely to the factory body lines that the transition between the OEM component and the TIKT Performance part visually disappears.
Those who don’t know a kit has been fitted will see a perfectly integrated factory car. Those who do will recognize the most aggressive detail on the vehicle.
Exposed instead of obstructed. The edge that determines the suction beneath the underbody.
The floor fences of the 992 GT3 RS are a serious aerodynamic component from the factory: they separate the airflow beneath the vehicle from the turbulence along the sides of the car. If this edge is obstructed by a side skirt extending too far downward, the underbody loses precisely the pressure differential that feeds the diffuser.
That is why our side skirt is deliberately raised, while the underbody edge is continuously reproduced in carbon. The fences remain exposed, airflow separation stays at the sides, and suction remains centralized.
A decision against the visually simpler solution — and in favor of the aerodynamically correct one.
Full carbon, one-piece. Significantly longer than conventional aftermarket diffusers. Flow-optimized to the maximum.
The diffuser is the largest untapped aerodynamic lever on the 992 GT3 RS. We have pushed it to its full potential: significantly longer than any other aftermarket diffuser known to us, manufactured from a single piece of full carbon — with no joints, no weak points, and no loss of strength at the most heavily loaded edges.
More diffuser surface area means greater suction beneath the underbody. More suction means more rear downforce. More rear downforce means a car that can get back on the throttle earlier and more progressively when exiting a corner. The angle of attack, channel geometry and separation edge are precisely tuned to prevent pressure loss and unwanted turbulence.
More efficiency per square centimeter is currently not possible in this vehicle class.
Full-carbon shell. CNC-machined, weight-optimized aluminum core. One of the most underrated aerodynamic upgrades for the rear wheels.
Aerodiscs aerodynamically enclose the rotating rear wheel on its outer side. What may look like a cosmetic modification is actually a classic Le Mans trick: an open wheel creates massive turbulence and pressure build-up as air flows past it — the tire effectively acts like a rotating air brake within the surrounding airflow.
The result: calmer airflow around the rear of the car, cleaner airflow toward the diffuser and rear wing, and significantly reduced parasitic aerodynamic drag at the rear wheel — delivering a measurable gain in efficiency at higher speeds.
Construction: full-carbon outer shell for rigidity and appearance, with a CNC-machined, weight-optimized aluminum core for dimensional accuracy, proper balance and secure mounting to the factory wheel. No flimsy plastic cover. A genuine engineered component.
Full carbon. Enlarged. Aerodynamically honest.
Endplates are where a rear wing proves whether it is truly engineered for performance. They prevent pressure equalization between the underside of the wing (low pressure) and the upper surface (high pressure) at the outer edges — exactly where smaller endplates allow a significant portion of the generated downforce to be lost.
Our endplates are enlarged and manufactured entirely from full carbon. The result: greater effective wing performance at the same angle of attack — more rear downforce without a disproportionate increase in aerodynamic drag. More performance in reserve when the track demands it.
The design is seamlessly integrated into the lines of the factory rear wing. No add-on brace aesthetic, but an endplate that looks as if Porsche itself had delivered it this way — only larger, sharper and more uncompromising.
Full carbon with integrated vortex generators. Aerodynamically optimized. Millimeter-perfect fit.
The rear window cover is more than just a visual component. Made entirely from carbon fiber, it performs two aerodynamic functions simultaneously: smooth, undisturbed airflow over the roof toward the rear wing — and controlled vortex generation through integrated vortex generators.
Vortex generators create controlled micro-vortices that add kinetic energy to the boundary layer. It may sound academic, but on the track it makes a real difference: the airflow remains attached to the rear section for longer instead of separating uncontrollably. The result is cleaner airflow over the main wing surface — more usable aerodynamic load at the wing and greater rear-end stability at Vmax.
Fitment: precisely matched to the factory contour down to the millimeter. No visible gaps, no height offset, no adhesive bulges.
Full carbon. The most stable car during load changes is always the one with a fin.
The Shark Fin is directly inspired by Le Mans and LMP regulations — and it is not there for visual reasons. A vertical fin along the roofline acts at high speeds like an aerodynamic stabilizing rudder that counteracts yaw movement.
Specifically, when the vehicle is hit by a crosswind, makes a rapid lane change, or tends to rotate under hard braking from 280+ km/h, the fin generates a restoring lateral force on the leeward side. The car stays more stable and linear in its path, steering corrections become smaller, and the driver remains calmer — and faster.
Construction: Full carbon, one-piece, precisely matched to the geometry of the factory roofline. On the racetrack, it provides an advantage in safety and performance. On the Autobahn, it makes a statement.
