Adro Porsche 992.1/992.2 GT3 AT-P Swan Neck Carbon Rear Wing A23A10-1501

The ADRO AT-P Swan Neck Wing A23A10-1501 is a serious aero upgrade for the Porsche 992.1 and 992.2 GT3. 

Rather than being purely cosmetic, its design focuses on increasing rear aerodynamic load while maintaining efficient airflow over the wing. ADRO lists it as compatible with all 992.1 and 992.2 GT3 trims. 

🔧 Core specification

Specification	ADRO A23A10-1501
Vehicle	Porsche 911 GT3 992.1 / 992.2
Wing type	AT-P dual-element Swan Neck
Main material	Prepreg carbon fiber
Uprights	Aluminum, LH + RH
Adjustment	6° of adjustment
Aero development	CFD-optimized
Mounting	Factory/OEM mounting points
SKU	A23A10-1501

ADRO’s supplied package consists of the complete dual-element wing assembly plus a pair of aluminum uprights. 

🧠 Engineering explanation

The important feature isn’t simply the large carbon blade—it’s the swan-neck architecture.

A conventional top-mounted support can disturb airflow approaching the underside of the wing. The ADRO configuration moves the structural support arrangement so that the wing surface can receive cleaner airflow. That matters because the wing’s pressure differential is what generates aerodynamic load.

Think of the system as:

Clean airflow → dual-element wing → pressure differential → rear downforce → greater rear-axle stability

The dual-element configuration is particularly interesting. The main element and secondary element interact aerodynamically, allowing the overall assembly to generate substantial load without requiring one enormous single airfoil.

⚙️ Why the 6° adjustment matters

The six-degree adjustment range gives the driver/team a way to alter the aerodynamic balance.

Lower angle
→ generally less aerodynamic loading
→ lower drag
→ better efficiency on straights

Higher angle
→ generally greater rear aerodynamic loading
→ stronger high-speed rear stability
→ increased aerodynamic drag

The critical point is that maximum downforce isn’t automatically maximum lap-time performance. The correct setting depends on the circuit, speed profile, tires, suspension setup and the rest of the aero package.

🏁 Why it suits the 992 GT3

The 992 GT3 already has an extremely sophisticated factory aerodynamic package. Therefore, an aftermarket wing needs to work as part of the car’s whole aero balance, not simply generate the biggest possible number.

ADRO says the AT-P was CFD-optimized for downforce, drag and stability, while its central “swooping” section is intended to improve efficiency. 

That’s why I’d categorize A23A10-1501 as:

OEM GT3 aero → ADRO aero optimization → track-oriented aerodynamic upgrade

rather than simply calling it a “big wing.”

🆚 A23A10-1501 vs ADRO AT-P2

ADRO also offers an AT-P2, SKU A23A11-1501, for the same 992.1/992.2 GT3 application. 

The A23A10-1501 is therefore the more elaborate AT-P option, with the distinctive dual-element design and six-degree adjustment highlighted by ADRO.

⭐ My technical rating

Category	Rating
Aerodynamic concept	9.5/10
Construction	9.5/10
Adjustability	9/10
Track suitability	9.5/10
Visual impact	10/10
Road practicality	7/10

APR GTC-200 Spec Wing - Toyota/Subaru GR86/BRZ 2022 - Up AS-105985

Part: AS-105985
Application: Toyota GR86 / Subaru BRZ, 2022+
Type: Adjustable carbon-fiber aerodynamic wing

This is a serious track-oriented aero upgrade, not simply a cosmetic spoiler. APR’s GTC-200 uses a 60.5-inch-wide, 10-inch-high airfoil designed to generate meaningful rear downforce while remaining relatively efficient. 

🔬 Technical breakdown

Specification	APR GTC-200
Wing span	60.5 in / ~1,537 mm
Height	10 in / ~254 mm
Airfoil	GTC-200
Main material	Pre-preg carbon-fiber CFRP
Carbon construction	3K, 2x2 twill
Finish	UV-stable clear coat
Pedestals	10 mm 6061 billet aluminium
Adjustment	Variable angle of attack
Mounting	Application-specific billet-aluminium bases
Hardware	Stainless-steel fasteners

APR specifies pre-preg carbon construction using high-temperature autoclave/vacuum-bag manufacturing, which is considerably more sophisticated than a conventional fiberglass or cosmetic carbon spoiler. 

🧠 What the wing actually does

Think of the GR86/BRZ as a front–rear aerodynamic balance system.

At increasing speed:

Air → wing → pressure differential → downforce → rear tyres

The additional vertical load can improve:

• High-speed cornering stability
• Rear-end confidence
• Braking stability
• Throttle application while cornering
• Resistance to high-speed rear-end lightness

The important point is that downforce increases with approximately the square of vehicle speed. So an aero package that feels subtle at road speeds can become dramatically more significant on a circuit.

The GTC-200 is therefore much more relevant to a track-focused GR86/BRZ than to a normal street car.

⚙️ Why the adjustable AOA matters

The wing can be tuned according to the circuit.

Lower AOA →
less drag + less downforce + better straight-line efficiency.

Higher AOA →
more rear aerodynamic load + greater stability + increased drag.

The current 60.5-inch specification also uses a variable-angle airfoil arrangement; APR lists a 14° difference between the center and outer-section angles for this version. 

That makes this more interesting than simply bolting on a huge fixed wing: you’re effectively adding another vehicle-balance tuning parameter.

🏁 GTC-200 vs GTC-300

APR’s GTC-300 is the more extreme aero solution, while the GTC-200 is better matched to the compact/midsize sports-car philosophy of the GR86/BRZ. Current listings show the GTC-300 for the platform at substantially higher prices, reflecting its more serious aero hardware.

For a GR86/BRZ track build, I’d characterize them as:

GTC-200 → fast street / HPDE / club racing
GTC-300 → dedicated high-downforce circuit build

🔥 Overall verdict

APR GTC-200 AS-105985: 9/10 for a track GR86/BRZ

The real strength isn’t just its aggressive appearance. It’s the combination of large span + carbon construction + adjustable aerodynamic geometry + rigid billet pedestals.

For a GR86/BRZ running upgraded tyres + suspension + brakes, the GTC-200 makes considerably more sense because the rest of the chassis can actually exploit the additional rear aerodynamic load.

TOMEI HIGH PERFORMANCE OIL PUMP FOR NISSAN SKYLINE GT-R BNR32 BCNR33 BNR34 RB26DETT 193035

 

TOMEI HIGH PERFORMANCE OIL PUMP FOR NISSAN SKYLINE GT-R BNR32 BCNR33 BNR34 RB26DETT 193035

The TOMEI 193035 is an upgraded high-volume oil pump specifically designed for the Nissan RB26DETT, used in the Skyline GT-R BNR32, BCNR33 and BNR34. 

Its main purpose is to solve one of the RB26’s critical weaknesses: maintaining reliable oil supply and pressure at high engine speed. 

🧠 Technical breakdown

Feature	Stock RB26 pump	TOMEI 193035
Pump gear	Sintered-metal type	SCM435 chromoly
Gear size	Standard	Larger/oversized
Flow @ 6,000 rpm	~42 - 47 L/min	~56 L/min
Oil-pressure adjustment	Limited	External adjustable system
High-RPM capability	Weak point	Substantially improved
Intended use	Standard engine	Performance/high-RPM RB26

TOMEI specifically redesigned the gear and cover. The SCM435 chromoly gear provides substantially greater strength, while the strengthened gear cover is intended to reduce cracking/failure risk. 

🔥 Why the RB26 benefits so much

The RB26DETT can experience lubrication problems when subjected to sustained high RPM, circuit use and heavily modified/high-output configurations. Insufficient oil delivery can cause oil-pressure loss and accelerated bearing wear.

The TOMEI pump increases theoretical flow from approximately 42–47 L/min to 56 L/min at 6,000 rpm—roughly a 19–33% increase, depending on which stock-flow figure is used. 

The important engineering distinction is:

More pump capacity ≠ automatically more useful oil pressure.

The engine’s bearing clearances, oil temperature, oil viscosity, galleries and relief-pressure setting all determine the pressure actually seen by the engine.

⚙️ The clever feature: external pressure adjustment

One particularly useful feature is the external oil-pressure adjustment, allowing the pressure to be adjusted without removing the oil pan. That’s a significant advantage during engine setup and calibration. 

For a serious RB26 build, this makes the pump more than simply a “bigger pump”; it becomes part of the engine’s oil-control system.

🛢️ Don’t overlook the oil pan

TOMEI recommends pairing the pump with a larger-capacity oil pan for performance applications. The reason is straightforward:

High-flow pump + insufficient oil volume + hard cornering = potential oil starvation.

A bigger pump cannot compensate indefinitely for an oil pickup that becomes uncovered during sustained acceleration, braking or cornering. TOMEI therefore recommends increased oil-pan capacity, although the pump remains compatible with the factory pan. 

🏁 Best application

I’d rate the 193035 particularly highly for:

• RB26 street/spirited build: ★★★★☆
• High-RPM engine: ★★★★★
• Circuit RB26: ★★★★★
• Drag/high-power RB26: ★★★★★
• Stock daily-driver RB26: ★★☆☆☆

The key benefit isn’t horsepower. It’s protecting the engine’s lubrication system when the RB26 is being pushed hard.

🔩 Ideal RB26 lubrication package

For a serious build, think of it as a system:

TOMEI 193035 pump → high-capacity/baffled oil pan → controlled oil pressure → reliable pickup → appropriate oil viscosity → healthy bearings/galleries

TOMEI’s current catalogue still lists 193035 as its RB26DETT High Performance Oil Pump; its Japanese price revision effective August 21, 2026 lists the new price at ¥158,000. 

Bottom line: the TOMEI 193035 is one of those RB26 upgrades that doesn’t make the dyno sheet dramatically more impressive, but it can make the engine much more resilient when high RPM and high power are involved. 

For an RB26 being built properly, oil control is foundational—not optional.
