SYMS RAM AIR BOX SYSTEM FOR TOYOTA GR86 ZN8 SUBARU BRZ ZD8 Y2000EG037
Here are some benefits and advantages you can expect (or hope) when installing the SYMS Ram Air Box System (Y2000EG037) on a Toyota GR86 ZN8 / Subaru BRZ ZD8:
What the SYMS Ram Air Box System is
Before going into benefits, here’s what this system claims to do (from product descriptions):
- It replaces the factory airbox and resonator assembly with a carbon fiber airbox + a redesigned duct/air path that maximizes intake duct size within limited space.
- It aims to introduce “ram air” — i.e. taking advantage of the vehicle’s forward motion to force higher-pressure (denser) air into the intake system.
- It is designed to be compatible with the factory ECU tuning (i.e. no mandatory retune) within the correction/flexibility range of the stock ECU.
- It uses carbon (or carbon composite) to combine performance benefits with aesthetic/weight advantages.
Given that, here are the advantages (and caveats) you might see.
Potential Benefits & Advantages
- Increased Airflow / Improved Volumetric Efficiency
- Because the ducting and internal geometry are optimized to reduce airflow restrictions, more air can reach the engine more efficiently.
- The “ram air” effect (at higher speeds) could help slightly increase the density (mass) of intake air, giving a small “boost” effect.
- With more air (if matched with proper fueling), the engine can produce more torque and power, especially in the upper RPM band.
- Better Throttle Response / Reduced Lag
- Because the intake path is more direct / less restrictive, the throttle (and engine) can respond more quickly to changes in load, especially at higher engine speeds.
- Less “intake lag” or delay between throttle input and air arriving in the combustion chambers.
- Aesthetic & Weight Advantages
- The use of carbon fiber material gives a premium look under the hood (carbon weave) which appeals to enthusiasts.
- Carbon fiber (or composite) is typically lighter than stock materials (plastic or metal), so there may be a small weight savings (though likely minor in the broader weight budget).
- Maintains Stock ECU / No Mandatory Retune
- One of its selling points is that it is usable within the correction range of the factory ECU (i.e., you may not need to reprogram or remap to take advantage).
- This means installation is more “bolt-on” friendly and you don’t necessarily have to risk messing with your stock engine calibration.
- Better Sound / Induction Noise
- Many aftermarket intake/ram air systems change the aural character of the engine (more intake “growl” or induction sound). While this is more subjective, it is a benefit some owners seek.
- Because resonators (or factory sound-damping parts) may be replaced or altered, you might hear more of the intake noise. (Note: this is also a potential drawback in noise-sensitive settings.)
Caveats, Limitations & What to Watch Out For
It’s important to temper expectations. Here are things to be cautious about:
- Modest Power Gains: While the claims suggest improvements, the actual horsepower/torque gains are often modest on a normally aspirated (non-forced induction) engine. Many intake upgrades yield small gains (few percent) unless the rest of the system (camshaft, exhaust, tuning) is also upgraded.
- Heat Soak / Intake Temperature: If the airbox is not sufficiently isolated from engine heat or if the ducting allows hot under-hood air ingress, performance could suffer due to warmer intake air. Some “cold air / ram air” designs struggle when the engine bay is hot.
- Speed-Dependent Benefit: The “ram air” effect is more effective at higher speeds. At lower speeds (city driving), the effect is minimal.
- Filter & Maintenance: Aftermarket systems may require more frequent cleaning or servicing of filters.
- Fitment & Packaging Constraints: Because the engine bay space is tight, routing, clearance, and making sure there’s no interference with other parts are critical.
- Warranty / Emissions Compliance: In some jurisdictions, aftermarket intake modifications may affect emissions legality or warranty status (depending on local regulations).
- ECU Limits: Even though it claims compatibility with the stock ECU, the stock engine control unit has limits on how much additional airflow/fuel it can adjust before requiring a reflash or supporting modifications (fuel injectors, etc.).
- Noise / Drone: Some setups may introduce undesirable induction noise or drone under certain RPM loads.
Summary
In summary, installing the SYMS Ram Air Box System (Y2000EG037) on a GR86 / BRZ can give you:
- Better airflow and possibly improved volumetric efficiency
- Slight boost (ram-air effect) at speed
- Quicker throttle response
- Cleaner, premium look with carbon fiber
- Maintainability with stock ECU (no required tune)
- Enhanced induction sound
However, don’t expect huge power leaps without complementary upgrades, and be mindful of intake temperature, fitment, and regulatory/warranty considerations.

GREDDY X VOLTEX REAR WING CENTER MOUNT CARBON FOR TOYOTA 86 ZN8 SUBARU BRZ ZD8 17010238
Here are the likely benefits — and trade-offs to watch out for — of installing the GREDDY × VOLTEX Rear Wing Center Mount Carbon (part no. 17010238) on a Toyota 86 / Subaru BRZ (ZN8 / ZD8):
Benefits:
- Increased downforce / improved stability at high speed
The wing is designed to “increase the downforce and chassis stability under higher speeds.”
Downforce at the rear helps push the rear tires into the road, improving grip when cornering, reducing oversteer tendencies, and giving you more confidence in fast turns. - Adjustable wing angle
The wing comes with a three-position adjustable angle to let you tune for the balance between downforce and drag.
This flexibility is useful to adapt to different driving conditions (e.g. street vs track). - Lightweight carbon construction & premium looks
The wing is made of wet carbon fiber (twill weave) for the blade, with clear coating.
Carbon helps keep weight lower compared to heavier materials (steel/aluminum/spoilers) and gives a more aggressive, race-inspired aesthetic. - Center mount configuration
The center mounting style gives a cleaner look (less obstruction on the trunk deck) and potentially more symmetric force distribution, compared to side mounts. Some sellers mention the wing “blends in well with the body” and is less visually obtrusive than “larger rear race wings.” - Complements an aero kit
As part of the GREDDY × VOLTEX aero kit family for the GR86 / BRZ, it integrates with front lips, side skirts, rear under spoiler, etc., for a balanced aerodynamic package.
Trade-offs & Considerations / Limitations
- Drag penalty / top speed tradeoff
More downforce almost always comes with more aerodynamic drag. On long straights or high speeds, the wing can reduce top speed or acceleration. You’ll need to balance wing angle to get usable benefit without too much drag. - Effectiveness threshold
The aerodynamic benefits will only become significant at higher speeds (e.g. track or highway speeds). At low speeds (city driving), you might not notice much difference. - Installation complexity & structural load
The wing requires drilling into the trunk or mounting points. Improper installation can cause stress, leaks, trunk damage, or structural fatigue.
Also, the mounting must be rigid to transmit loads safely. - Added weight (albeit small)
Even carbon wings add some weight (brackets, bolts, reinforcements). Though minimal, the center of mass shift matters in a lightweight car like the 86/BRZ. - Cost / ROI
It is a premium part, so the cost is high. The performance gain (especially for street use) may not fully justify the cost.
BLITZ ZZ-R DSC PLUS COILOVER SUSPENSION SET FOR HONDA CIVIC TYPE R FL5 K20C 98395
Here are some advantages of the BLITZ ZZ-R Spec DSC Plus Coilover Set (part number 98395) for the Honda Civic Type R FL5 (K20C), based on its specs and features.
✔️ Key Advantages
- Electronically adjustable damping (DSC Plus)
- You can adjust how hard or soft each damper is from inside the car, which allows you to tune ride comfort vs handling responsiveness without needing to touch the shocks themselves.
- Up to 96 steps of damping force adjustment. More granularity means finer control.
- Has different modes (Standard, Advanced, etc.), plus “Full Auto” / map-based control, which adapts damping based on speed, G-forces, etc. That means it can be more comfortable during normal driving but stiffer when you push hard.
- Full-length adjustability
- The coilovers allow adjusting the full length of the shock (i.e. ride height) independent of spring length or preload. This helps you lower the car without sacrificing travel or causing weird changes in handling.
- Ride height range is substantial, especially up front: e.g. front: about −57 mm to 0 mm from stock. This lets you dial in a sporty stance without over-lowering.
- Stiffer springs & better control
- Spring rates are higher than stock, e.g. front ≈ 12.0 kgf/mm, rear ≈ 10.0 kgf/mm. This helps reduce body roll, improve cornering stability, and give more direct feedback.
- The upper mounts are reinforced / improved: adjustable pillow (pillowball) type up front, reinforced rubber in the rear. Better mounts help maintain alignment under load and improve feel.
- Components quality & durability
- Use of materials like high-tensile springs, improved corrosion resistance (coating, special treatments) for parts like cylinder case.
- Full-length adjustability means you can maintain travel and ride quality even after lowering; reduces risk of bottoming out or hitting bump stops prematurely.
- Better performance both on road and track
- The combination of adjustable damping, stiff springs, and adjustable ride height makes this set suitable for dual use: daily driving, spirited mountain or road-twisties, plus occasional track use. You can tune the suspension for comfort or for track, depending on the situation.
- Improved stability, better control under braking, cornering, and in varied load / speed conditions thanks to the DSC Plus and sensor inputs (G-sensor, vehicle speed etc.).

VW GOLF MK6 R SCORPION CATALYST BACK EXHAUST WITH RESONATOR SKU: FMSVW038
VW GOLF MK6 R SCORPION CATALYST BACK EXHAUST WITH RESONATOR SKU: FMSVW038
Here are some of the advantages (and a few trade‐offs) of the Scorpion Cat-Back Exhaust SVW038 (Resonated / Catalyst Back) on the VW Golf MK6 R, especially compared to stock / other exhaust options.
What the Scorpion SVW038 System Offers
From its specs / descriptions:
- Pipe diameter: 3″ (76 mm) stainless steel, mandrel bent.
- Resonated version (so has a centre silencer / chamber) to reduce harsh noise / drone in cruising / mid-RPM.
- Polished twin 100 mm Daytona tailpipes.
- Retains active exhaust valves.
- Legal / road-usable more than non-resonated or decat systems (especially in some jurisdictions) because of the resonator and likely keeping the OEM catalyst or using an approved component in the “cat-back” portion.
Advantages vs Stock / Other Exhaust Setups
Here are what people generally gain, and what this Scorpion system gives you, compared to stock or lesser exhausts:
|
Benefit |
Explanation / How SVW038 Delivers |
|
Improved Exhaust Flow / Reduced Back-Pressure |
The larger diameter and smoother mandrel bends allow exhaust gases to exit more freely, reducing restriction vs OEM piping. This helps turbo response, especially under heavier load. |
|
Better Sound / Tone |
More aggressive, sporty exhaust note, especially under load or high revs. The resonated version balances this with reduced drone and less harshness at highway cruising. |
|
Aesthetic Upgrades |
Polished twin Daytona tips look nicer; stainless steel gives durability and better finish vs possibly more basic OEM mufflers. |
|
Weight Reduction |
Aftermarket cat-back systems are often lighter than OEM due to thinner, more optimized materials and simpler construction. This helps with overall weight (especially rotating mass) and handling. The Scorpion descriptions mention some weight savings. |
|
Retention of Road Legality / Comfort |
Since this is a resonated, catalyst-back system, it tends to stay within acceptable sound limits, retains catalytic conversion, and is more likely to pass inspections / emissions tests. Also better for daily driving because less noise, less annoyance. |
|
Flexibility |
The Scorpion offers versions (resonated vs non-resonated) giving a choice depending on how loud you want it. Also works well with OEM or other aftermarket downpipes / cats. |

ORC SE CLUTCH ORC-1000F-SE TRIPLE FOR TOYOTA SUPRA ORC-1000F-TT0101-SE
Here are the technical advantages (and trade-offs) of the ORC SE Series Triple (ORC-1000F-TT0101-SE) clutch for the Toyota Supra (2JZ-GTE / JZA80).
Key Technical Advantages
- High Torque Capacity
The ORC 1000F series is built to take very high torque loads. The SE version doesn’t reduce this capability significantly, so you get a clutch suitable for serious power. For example, the metal/triple 1000F variants are rated around 980 Nm (≈100 kgf·m). - Triple Disc Design
Having three friction discs increases the total friction area. More area means you can clamp more torque without slipping, allow for higher power, better durability under heavy load, and better heat dissipation (since more surface is sharing the load and heat). Helpful when riding boost, doing drag launches, drifting, etc. - “SE” (Smart Engage / Cushioning) Mechanism
The SE version incorporates a pressure plate with cushioning. What this does:
- Expands the half-clutch engagement range, which means smoother modulation of clutch bite—less abrupt launching, less jerky in stop‐start or drifting transitions.
- Reduces drivetrain shock when engaging, shifting, etc., thereby protecting gearbox/differential components, driveshafts. This mechanism reduces impact torque (when the clutch fully re-engages) by a meaningful percentage compared to standard rigid performance clutches.
- Street + Track Versatility
Because of the smooth engagement and high capacity, this clutch can work well both for high-power track or drift uses and for occasional street usage without making the car unbearable in traffic. Many hardcore clutches are usable only at full load or in racing conditions. The SE aims to be more user-friendly. - Included Hardware / Complete Kit
The kit includes release bearing (B type), sleeve bearings, and flywheel bolts. So setup is more plug-and-play (assuming correct fitment) without needing to source extra parts. - Push Mechanism
It uses a push type mechanism (i.e. a push-style release bearing). Depending on Supra’s setup (the JZA80 manual transmission), push vs pull can affect leverage, throw, pedal travel, etc. Push systems can be simpler to package.
