APR GTC-200 Adjustable Carbon Fiber Rear Wing for 02-06 RSX

APR GTC-200 Adjustable Carbon Fiber Rear Wing (APR-AS-105920) - 2002-2006 Acura RSX

A real wing transforms how a light K20 chassis like the DC5 RSX behaves at speed, and the APR GTC-200 is the efficiency standout of APR's wing range to do it. Its CFD-developed cambered airfoil hits an 11:1 downforce-to-drag ratio, meaning it generates serious rear downforce for very little drag penalty. It's a mid-sized, fully adjustable wing, sized right for a car like the RSX that carries corner speed and doesn't need the extreme load of a massive wing to transform how it drives.

What A Wing Actually Does

Worth explaining, since it's the whole reason to fit one.

At speed, a car generates lift, air moving over the body lightens it, and a light rear end feels nervous and loses traction exactly when you're cornering hard. A wing reverses that at the back of the car: it's effectively an upside-down airplane wing, generating downforce that presses the rear tires into the road.

More vertical load on the rear tires means more grip, which translates into higher cornering speeds, more stability under braking, and a car that's planted and predictable rather than loose. On a chassis as light and responsive as the RSX, that added rear grip is genuinely transformative on track.

11:1 Downforce-To-Drag, The Efficiency Leader

This is the GTC-200's headline, and it's the best ratio in APR's wing range.

The CFD-developed, cambered airfoil achieves an 11:1 downforce-to-drag ratio, which is exceptional, it makes a lot of downforce while adding very little drag. For comparison, APR's GT-250 runs 7.6:1 and the larger GTC-300 runs 8.8:1, so the GTC-200 actually sheds the least drag per unit of downforce of the three.

That efficiency is exactly what a lighter car like the RSX wants. You get the rear grip without a big top-speed penalty, which is the ideal balance for a car that's about carrying corner speed rather than brute straight-line power. The cambered airfoil creates a strong pressure differential across the wing while keeping airflow attached at speed, which is where that efficiency comes from.

Adjustable To Any Track

This is what makes a real wing worth it over a fixed one.

The GTC-200 has a fully adjustable angle of attack from 0° to 15°. Dial in more angle for a tight, technical track where you want maximum downforce and cornering grip; back it off for a fast circuit where you want minimum drag and more straight-line speed. One wing adapts to different tracks and lets you set the rear balance to match your front aero.

The wing also mounts on adjustable 10mm 6061 billet aluminum risers, variable from 7" in height, so you can fine-tune the wing's height and position for optimal airflow and downforce distribution. A variable chord depth (7.5"-9.5") further tunes how much wing is working. It's a genuinely adjustable aero tool, not a one-setting part.

Pre-Preg Carbon, Built To Not Flex

Wing rigidity matters more than people realize.

The GTC-200 is pre-preg woven carbon fiber, autoclave-cured in billet aluminum molds, which gives it the strength-to-weight and the stiffness to not flex under aero load. A wing that flexes at speed changes its angle as it loads up, making its downforce inconsistent right when you're relying on it. This holds its shape, so the aero stays predictable, and the carbon construction keeps it light at the back of the car.

Where The GTC-200 Fits In The Range

Honest framing against APR's other wings, since they're worth cross-shopping.

The GTC-200 is the mid-sized, most efficient option, ideal for lighter track and time-attack cars like the RSX that want strong downforce without excessive drag. Step up to the larger GTC-300 if you're running a heavier or higher-power car that needs more total downforce capacity. For the RSX specifically, the GTC-200's size and efficiency are the sweet spot, enough downforce to transform the car, without more drag than a light chassis needs.

Fitment Note

One thing to know about the install on the RSX.

This uses APR's vehicle-specific carbon fiber bottom plates for a secure mount, and the mounting bases cover the factory spoiler/wing holes. So if your trunk has the factory wing holes, this wing's bases hide them, which is clean if you're removing a factory wing, just worth knowing before install.

An optional gurney flap (½" pre-preg carbon, tape-on) is available to add further downforce and reduce flow separation when you want the wing at its most aggressive.
