The Yokohama World Time Attack Challenge returns to Sydney Motorsport Park on 4-5 September 2026, and for most competitors aerodynamics will decide where they finish. This guide breaks down the APR Performance wing range — GTC-200, GT-250, GTC-300, GT-1000 and the flagship GT-2000 — plus the splitters, canards and aero kits that make a wing work properly.
WTAC 2026 — Is Your Aero Ready?
Two days of the fastest time attack racing on the planet, chasing the one perfect lap around the 3.93km GP circuit. Whether you are building for WTAC, prepping for club-level time attack, or simply want your track day car to be more stable at speed, aero is no longer optional. Downforce improves corner speed, braking stability and traction without adding weight or mechanical complexity to the chassis. The question is not whether you need aero, but which components deliver real results versus those that are purely cosmetic.
APR Performance has been at the centre of competitive aero for over two decades. Their wings, splitters, canards and aero kits are found on time attack cars, WTAC competitors and track-focused street builds around the world. Every product is designed using Computational Fluid Dynamics (CFD), manufactured from pre-preg carbon fibre and autoclave-cured for maximum strength at minimum weight. This is not dress-up carbon — it is functional aerodynamics backed by engineering data.
Why Aerodynamics Matter at WTAC-Level Speeds
At the speeds WTAC cars carry through corners — often well above 150km/h — aerodynamic forces become the dominant factor in grip. Mechanical grip from tyres and suspension reaches its limits, and beyond that point downforce is the only way to push harder. A well-designed rear wing can generate hundreds of kilograms of downforce at speed, effectively pressing the car into the track surface and allowing the tyres to work harder without losing traction.
But downforce is only useful if the aero balance is correct. Too much rear downforce without front grip creates understeer. A rear wing without a front splitter shifts the balance rearward and can make the car unpredictable under braking. This is why a complete aero package — wing, splitter and side management — is always more effective than bolting on a single component in isolation.
APR Performance designs their products with this principle in mind. The wing range spans from the compact GTC-200 for lighter platforms, through the GT-250 and GTC-300 for serious track builds, up to the dual-element GT-1000 and GT-2000. Each is designed to work as part of a balanced aerodynamic system alongside APR's front splitters, canards and side skirts.
APR Performance Wing Guide — Which One Is Right for Your Build?
GTC-200 — Entry-Level Track Aero
The GTC-200 is APR's most compact wing, optimised for lighter and smaller platforms. With a 60.5-inch span and 7-inch height, it delivers meaningful rear downforce without overwhelming the car's balance on platforms like the Mazda MX-5. The 3D airfoil design is CFD-tested and manufactured from pre-preg carbon fibre with aircraft-grade 6061 billet aluminium pedestals.
Best for: Mazda MX-5 (NA, NB, NC), lighter track cars, and builds where a proportional wing size matters for both aesthetics and aero balance.
GT-250 — The Track Day Favourite
The GT-250 is APR's most popular wing for track-focused builds. Available in 61-inch and 67-inch spans, it uses a 2D airfoil profile that generates uniform downforce across the entire width of the wing with minimal drag. The 2D design means the airfoil shape is consistent from end to end, making it predictable and easy to tune with angle adjustments.
The GT-250 is also available in a swan neck configuration, where the mounting pedestals attach from above the wing plane rather than below. This keeps the underside of the airfoil clean and undisturbed, maximising the effective downforce area. The swan neck version is particularly effective on the Honda Civic Type R FL5, where it mounts to the factory spoiler location and transforms the car's high-speed stability.
Best for: Honda Civic Type R (FK8, FL5), Nissan 350Z, Subaru WRX/STI, and most mid-level track builds. A go-to choice for WTAC Clubsprint and Tuner Class competitors who need proven, adjustable downforce without the complexity of a GT-1000.
GTC-300 — Maximum Attack
The GTC-300 is the largest wing in APR's adjustable range, available in 61-inch and 67-inch spans with a 13-inch height. It uses a 3D airfoil profile — meaning the wing shape varies across its span to optimise airflow and generate higher peak downforce than the 2D GT-250. This comes with slightly more drag, but for cars chasing outright lap time the additional rear grip is worth it.
The GTC-300 is the choice for serious time attack builds where every tenth counts. It delivers aggressive downforce that keeps the rear planted through high-speed corners and under heavy braking. On the Honda Civic Type R FK8 it bolts directly to the factory spoiler mounting holes with no drilling required.
Best for: Honda Civic Type R (FK8, FL5), Nissan 370Z, Mazda MX-5 (NA/NB), and dedicated time attack or circuit racing builds chasing maximum rear downforce.
GT-1000 — Pro-Level Downforce
The GT-1000 is a dual-element wing designed for serious competition builds that need significant aerodynamic load beyond what single-element wings can deliver. It is commonly seen on fast time attack cars competing at national and international level, and it provides a substantial step up in downforce from the GTC-300. If you are building a dedicated track car and need chassis-mounted aero that delivers at speed, the GT-1000 is a proven choice.
Best for: Pro-Am and Open Class time attack builds, dedicated circuit racing cars, and vehicles with the mechanical grip, suspension and chassis preparation to exploit high downforce levels.
GT-2000 — The Flagship, Maximum Downforce
The GT-2000 is the newest and most advanced wing in APR's lineup — the flagship of the entire range. It is a dual-element wing featuring two 10-inch chord foils that create an aggressive pressure differential, generating the highest downforce output of any APR product. With a 78-inch span and an adjustable angle of attack ranging from 14° to 22°, the GT-2000 delivers an 8:1 downforce-to-drag ratio, making it one of the most efficient high-downforce wings available anywhere.
The GT-2000 is a chassis-mount wing — it must be mounted to the vehicle's roll cage or chassis structure, not the boot lid. The downforce levels it generates would deform even a factory steel boot lid, so custom fabricated pedestals and a proper chassis mounting system are required. This is not a bolt-on product; it is an engineering commitment that requires fabrication and planning, and installation by a professional fabricator is strongly recommended.
Best for: The absolute pointy end of time attack and motorsport. WTAC Pro Class and Open Class competitors chasing outright lap records, unlimited class competition cars, and any build where maximum aerodynamic performance is the priority.

Beyond the Wing — Completing the Aero Package
A rear wing is only one part of the equation. APR Performance manufactures a complete range of aero components designed to work together and deliver balanced downforce across the entire car.
Front Splitters and Air Dams
APR's carbon fibre front splitters create a high-pressure zone above the splitter plane and a low-pressure zone beneath it, reducing front-end lift and increasing front tyre grip. This is critical for balancing the rear downforce from a wing — without front aero, the car will push into understeer at speed. APR offers vehicle-specific splitters for the Subaru WRX/STI, Honda Civic Type R and other popular platforms, each designed to cover the full area beneath the front bumper for maximum effectiveness.
Canards
Carbon fibre canards mount to the front bumper and generate localised front downforce while also directing airflow around the front guards. They are a simple, bolt-on way to fine-tune front aero balance without a full splitter, and they work well as a complement to a splitter on cars where maximum front grip is needed. APR offers vehicle-specific canards for the Subaru WRX/STI with UV-resistant clear coat for long-term durability.
Side Skirts and Rear Bumper Skirts
Side and rear bumper skirts manage airflow along the sides and rear of the vehicle, preventing turbulent air from wrapping underneath the car and disrupting the low-pressure zone created by the splitter and diffuser. APR's carbon fibre rear bumper skirts for the R35 GT-R are a prime example — designed to reduce rear-end lift and improve stability at high speed.
Complete Aero Kits
For a fully integrated approach, APR offers complete aero kits that bundle the front air dam, side rocker extensions and rear bumper skirts into a single package. The Subaru WRX/STI aero kit is a popular choice for track-prepped cars that want balanced aero improvement across the entire vehicle without mixing and matching individual components.
Preparing Your Car for WTAC 2026
If you are building a car for WTAC 2026 — or preparing for any time attack event in Australia — aero should be part of your plan from the start, not an afterthought bolted on the week before the event.
Early in the year: Decide on your aero package and order early. APR wings are made to order, so allow time for manufacturing, shipping, fitting and alignment before your first test day. If you are running a wing for the first time, plan at least one full test session to dial in the angle of attack and assess the balance.
Mid-year: Test and tune. Get the car on track with the aero fitted and assess the handling balance. Adjust wing angle, check front-to-rear aero balance, and ensure the splitter and any canards are securely mounted and not contacting the ground under compression.
August: Final preparation. Inspect all aero mounting points for fatigue or loosening. Check carbon fibre surfaces for stone damage or delamination. Confirm compliance with your WTAC class regulations — wing dimensions, mounting locations and materials may be regulated depending on your class.
4-5 September: WTAC 2026 at Sydney Motorsport Park. Chase the one perfect lap.
Wings, splitters and canards carry significant aerodynamic load, so fitting and mounting by a professional workshop or fabricator is recommended.
FAQ
What is the difference between a 2D and 3D airfoil wing?
A 2D airfoil (like the GT-250) has a consistent cross-section across its entire span — the wing shape is the same from end to end. This produces uniform, predictable downforce with lower drag. A 3D airfoil (like the GTC-300) varies in shape across the span, which can generate higher peak downforce but with slightly more drag. For most track builds a 2D airfoil offers the best balance of downforce and efficiency; for outright lap time at higher speeds, a 3D airfoil delivers more total rear grip.
Do I need a front splitter if I'm running a rear wing?
Strongly recommended, yes. A rear wing generates significant rear downforce, which shifts the aero balance rearward. Without corresponding front downforce from a splitter or air dam, the car will develop understeer at speed as the rear is pushed down harder than the front. Balanced aero — front and rear working together — is always more effective than a wing on its own.
Are APR wings legal for WTAC competition?
APR wings are used by WTAC competitors across multiple classes. However, each WTAC class has specific rules regarding wing dimensions, mounting locations and materials. Check the current WTAC technical regulations for your class before ordering to ensure your chosen wing complies. For Clubsprint and Tuner Class, the GT-250 and GTC-300 are commonly used within regulations.
What is a swan neck wing mount?
A swan neck mount attaches to the wing from above rather than below. This keeps the underside of the airfoil — where the low-pressure zone generates downforce — completely unobstructed by pedestal mounts. The result is cleaner airflow and improved aerodynamic efficiency. APR's GT-250 swan neck variant is available for the Honda Civic Type R FL5.
Can a GT-2000 be mounted to the boot lid?
No. The GT-2000 is a chassis-mount wing and must be mounted to the roll cage or chassis structure using custom fabricated pedestals. The downforce it generates would deform a factory boot lid.
