APR Performance GT vs GTC Wings: How to Choose
APR GT vs GTC Wings: How to Choose the Right APR Performance Wing
If you've spent any time shopping APR Performance, you've run into the same wall most buyers hit: the lineup splits into two series — GT and GTC — with model numbers like GT-250, GTC-300, and GTC-500 that don't tell you much on their own. Most product pages list specs and let you guess at the rest. This guide cuts through the noise. Here's exactly how the two series differ, what the numbers mean, and how to pick the right wing platform for your car and the way you actually drive it.
The Quick Answer
APR Performance builds its rear wings around two distinct airfoil philosophies. The GT Series uses a 2D airfoil — the cross-section stays uniform across the entire span, which lets the wing produce consistent downforce from end to end. The GTC Series uses a 3D airfoil with cambered surfaces that vary through the span, tuned for a higher downforce-to-drag ratio. Beyond the airfoil, the model numbers (200, 250, 300, 500, 1000) roughly correspond to how much downforce the wing can produce and what size of car it's designed for. Bigger numbers, bigger cars, more downforce.
If you're chasing peak downforce for a track or time-attack build, the GT Series is engineered for that. If you want a balanced wing that looks proportional on a street car and doesn't punish your top speed, the GTC Series is usually the better fit. The rest of this guide explains why.
GT Series: 2D Airfoil, Built for Peak Downforce
The GT Series is APR's purpose-built track lineup. The 2D airfoil shape means the cross-section of the wing stays the same from one tip to the other, which lets it generate consistent downforce across its full span. That sounds simple, but it matters — a uniformly profiled wing avoids the local performance dropoffs that happen when an airfoil tapers, and it gives chassis tuners predictable behavior at high angles of attack. The tradeoff is some efficiency loss compared to a 3D profile, which is why the GT Series tends to live on dedicated track cars where peak downforce matters more than top speed.
GT-250
The GT-250 is the mainstream GT-Series wing — single element, available in 61" and 67" spans, and built for compact and midsize performance cars. It runs a 0–15° angle-of-attack adjustment range and a 7.6:1 downforce-to-drag ratio, which means it produces strong absolute downforce in exchange for a modest drag penalty. Gurney flaps come pre-installed, which is one of the reasons it's become the wing of choice for time-attack regulars on platforms like the BMW M2, GR Corolla, and FL5 Civic Type R.
APR also offers a swan neck variant of the GT-250, which mounts the wing from above instead of from below. The swan neck design keeps the underside of the airfoil clean — that's the high-pressure side that does most of the actual aerodynamic work — and reduces the flow separation that bottom-mount pedestals create. It's the more aggressive option both visually and aerodynamically. The GT-250 wing for the BMW G42 M240i and G87 M2 is a good example of how the same wing platform gets adapted to a specific chassis with the right mounting hardware.
GT-1000
The GT-1000 is the top of the GT Series and a fundamentally different tool. It's a dual-element wing — a primary airfoil with a secondary blade above it — and it's engineered to produce up to 1,650 lbf of downforce at 160 mph. The secondary airfoil has an angle-of-attack range of 10–52°, and APR specifies that it doesn't stall even at 52°, which gives serious teams a wide tuning window for circuit-specific setups. It's universal fitment, requires chassis-mounted pedestals (you cannot trunk-mount a GT-1000 — the loads will deform a factory trunk lid), and is targeted squarely at widebody time-attack and pro-level track cars where peak downforce trumps everything else.
GTC Series: 3D Airfoil, Sized to the Car
The GTC Series is the broader, more versatile lineup, and where most street and weekend-track cars land. The 3D airfoil profile has cambered surfaces with curvature that varies through the span — APR's term is "optimized 3D" — and it's tuned for a higher downforce-to-drag ratio than the GT Series. In practical terms, a GTC wing produces less peak downforce than a comparable GT wing but loses less top speed in the process, which is why it dominates high-speed touring and street-driven track car applications.
The 200 / 300 / 500 numbers loosely scale with intended car size and downforce capability.
GTC-200
The GTC-200 is the smallest in the series — roughly 60.5" wide and 10" tall — and it's intended for compact and midsize cars where a larger wing would look out of place. It runs an 11:1 downforce-to-drag ratio, which is the highest in APR's catalog, making it one of the most efficient wings in the lineup pound-for-pound. There's also a low-profile "Drag" variant at 5" tall, designed for hatchbacks, lift-backs, and top-speed builds where you want some downforce without the drag of a full-height wing.
GTC-300
The GTC-300 steps up to 61" or 67" spans, with up to 13" of overall height and a more aggressive airfoil. It's the catch-all for mid-to-large performance cars and serious track builds — the platform you'll see on E46 M3s, S2000s, Mitsubishi Evos, and pretty much every chassis where the GTC-200 looks small. Most of APR's hero builds at SEMA and Time Attack events run a GTC-300 in some form.
GTC-500
The GTC-500 is the largest wing in APR's catalog at up to 74" wide. It's built around the same 3D airfoil philosophy as the rest of the GTC line but scaled for full-size sports cars, GT racing chassis, and high-speed touring applications. You'll typically see it on platforms like the C7 and C8 Corvette, where the car has both the width to support the span and the speed to use the downforce. The GTC-500 wing for the C8 Z06 is a good example of how the wing's chassis-mount geometry gets purpose-built for each platform.
How to Choose Between GT and GTC
Once you understand the airfoil difference, picking between the two series usually comes down to four practical questions.
How big is your car?
Wing span needs to roughly match track width — both for the wing to look right and for it to actually work in clean air. Compact cars like the Civic Type R, BRZ, or S2000 live in the GTC-200 or 61" GT-250 range. Midsize sports cars like the M2, M4, or A90 Supra work well with the 67" GT-250 or the GTC-300. Full-size GT cars and Corvettes need the GTC-500 to look proportional and to actually use the additional span.
Track tool or street build?
If the car will see real track time and you're chasing lap times, the GT Series is the more focused choice — particularly the GT-250 with swan neck pedestals. If the car splits time between canyons, the autobahn, and the occasional track day, the GTC Series gives you usable downforce with a smaller drag penalty and looks more cohesive on a street car.
Single element or dual?
Single-element wings — every GT-250 and every GTC — are sufficient for the vast majority of builds, including serious club-level track cars. Dual-element wings like the GT-1000 are specialized tools. They produce extreme downforce, they require chassis fabrication for the mounting (trunk lids will deform under load), and they're overkill for any street car. If you're asking the question, you almost certainly want a single-element wing.
Standard pedestals or swan neck?
Standard bottom-mount pedestals support the wing from below, which means the mounts sit directly in the high-pressure side of the airfoil and create some flow separation. Swan neck pedestals mount from above, keeping the underside clean and letting the wing run a higher angle of attack before stalling. Swan necks cost more, look more aggressive, and produce slightly more usable downforce — but standard mounts are perfectly capable for street and entry-level track use.

Where to Start
For most buyers, the decision tree is simple. Smaller chassis, mixed-use car, want efficiency and proportion — GTC Series sized to your platform. Smaller chassis, dedicated track car, willing to give up some top speed for grip — GT-250, with swan neck if budget allows. Larger chassis like a Corvette or full-size GT — GTC-500. Pro-level track or time-attack build with chassis fabrication on the table — GT-1000.
Once you've narrowed the series, the next step is finding the wing that's been validated for your specific platform. The mounting hardware, fitment plates, and bracket geometry are all chassis-specific, even when the airfoil itself is shared across applications. You can browse the full lineup on our APR Performance collection page, filter to your car, and compare options. If you're not sure which size or mount style fits your build, our team can help you walk through it — fitment on aero parts is worth getting right the first time.
