Installation Precautions (For Installers)

Degreasing Work

Also refer to the separate “Degreasing Procedure” sheet.

• When performing degreasing, use a clean cloth and use white gasoline, isopropyl alcohol (IPA), or “Silicone Off” handled by TACTI Co., Ltd., to degrease thoroughly. Do not use silicone-off products other than the specified one.
• Do not use body coating base agents, parts cleaners, brake cleaner, or other solvents for degreasing. Inadequate degreasing will cause lifting and peeling.

Double‑sided Tape

• If degreasing is insufficient, the double‑sided tape will peel off even if it is applied.
• Once the double‑sided tape is applied and then peeled off, its adhesive strength will decrease and it cannot be reused.
• The adhesive performance of the double‑sided tape supplied with this product is significantly reduced at ambient temperatures of 20 °C or lower. If the temperature is too low, the tape may peel.
• Press the double‑sided tape firmly with a pressure of at least 49 N (5 kgf, enough to make the vehicle shake lightly). Insufficient pressure will cause peeling.
• For 24 hours after installing this product, do not allow car washing, water (including wiping with water), or rain to contact the product. Failure to observe this may cause lifting or peeling.

Painting Work for Unpainted Product

• Before painting this product, undercoat treatment is required. Always start with surfacer (primer) painting.
• When painting this product, mask all double‑sided tape areas completely.
• When drying, fix the product in a way that prevents deformation. High drying temperatures may cause deformation or cracking; therefore, dry at 70 °C or lower.

After Installation

• After installation, check that this product does not interfere with the vehicle body.
• If you disconnected the negative terminal of the battery during work, be sure to perform system setting and confirmation after completing the work.

Precautions

⚠️ Attention

The installation of this product will change the feel of the trunk lid opening and closing operation.
The installation of this product will reduce the amount of pop-up of the trunk lid when the trunk lid is opened, making it difficult to recognize the appearance of the trunk lid.
Please make sure that the trunk lid is closed before driving.
Carbon products are structurally designed so that the shading of the carbon mesh, irregular gaps, and undulation of the fibers may be visible. These are due to the characteristics of real carbon. Please understand this in advance.
To protect the product from scratches, deformation, and damage, please pay attention to the following.
Do not hold the spoiler when opening and closing the trunk lid.
Do not operate the trunk lid suddenly when opening or closing it.
For cleaning, use plenty of water to lift sand and dust, and wash it off gently with a soft sponge or the like.
Do not scrub hard in parts.
To prevent damage, please do not use a car wash machine.

The 2022 ZD8 Subaru BRZ has two small changes that are not seen on the 2022 ZN8 Toyota GR86. That is the front aluminum uprights (which reduce unsprung weight) and the rear swaybar mounting method. Both of these changes are good, but fairly minor overall.

Three other changes to the second generation are as follows:

• Increased rear motion ratio
• Increased rear track width
• Chassis stiffening

An increase in rear motion ratio on the second generation cars (due to a slight change in rear spring/shock mounting points) means that with identical springs, the newer car will have a slightly stiffer wheel rate, or spring rate at the wheels, compared to the first generation.

For example, a 300 lbs/in rear spring on the first generation car equates to about 173 lbs/in in wheel rate. On the second generation car, that same spring would mean about 183 lbs/in in wheel rate. A small difference that means a slight increase in the tendency to oversteer.

Meanwhile, the slight increase in rear track width reduces rear weight transfer in a corner and reduces overall weight transfer. This means slightly more rear grip and less oversteer. An analysis of the total lateral load transfer distribution (TLLTD) of each car indicates that these two changes do essentially balance out in terms of oversteer and understeer.

A key change to the second generation car is the stiffer chassis structure itself. This can be felt from the driver’s seat but is difficult to quantify. Reducing chassis flex has the effect of an overall increase in spring rate and the car will feel slightly firmer with the same spring rates.

An important consideration is that a car with a stiffer chassis structure (second generation) will be more sensitive to suspension changes than one a softer chassis structure (first generation). This means that while poorly chosen spring rates on an earlier car is not a complete disaster, a properly designed suspension is necessary for the later cars to maintain a good handling balance and performance.

Toyota Techstream is diagnostic software that allows you to diagnose and troubleshoot issues with Toyota and some Subaru vehicles. It reads and clears diagnostic trouble codes (DTCs) that are stored in the vehicle's on-board computer. It also provides access to various functions and systems in the vehicle, such as the engine control system, transmission system, and ABS (anti-lock brake system), so that technicians can perform tests and make adjustments as needed.

To read codes with Toyota Techstream, you will need to connect a ODB-II to USB cable to the vehicle's ODB-II port. The technician will then start the Techstream software and follow the prompts to access the diagnostic functions of the vehicle. Once the diagnostic functions are accessed, the technician can retrieve the stored DTCs and use them to diagnose and fix the issue with the vehicle.

Subaru SSM4 is Toyota's equivalent of Techstream, their dealer tool to read, set and manipulate values in the ECU, but there isn't much difference of the capabilities.

| EDA | Purpose | |:---|:---| | VSC | Vehicle Stability Control, often known generically as ESC or Electronic Stability Control). This program identifies understeer (running wide, needing more and more lock to turn) and oversteer (back slipping out). It then corrects the car’s course by braking individual wheels, and in extreme cases, also reducing throttle to avoid making things worse. Subaru called VSC by the generic term of ESC. | | TRC | Engine Traction Control. If you have both rear wheels spinning this system figures out you’re going nowhere and reduces the throttle. The 86/BRZ refers to this as TRC, or Traction Control, although it is a distinct programme from brake traction control (below). In 86-speak, TRC stands for “Traction Control System”. No, I don’t know why. Subaru call it TCS, or Traction Control System. | | B-TRC / Brake-LSD (name from MY17 onwards) | Brake Traction Control. If one drive wheel spins up faster than the other this system detects that spin and brakes the spinning wheel which sends torque (“drive”) to the other wheel, so you can keep moving forwards. There is no official acronym for this system because it is not mentioned anywhere, but nevertheless it exists. For the purposes of this guide it’ll be known as B-TRC, because it is traction control operated via brakes as opposed to traction control by modulation of the throttle. This system is also known as an ‘LSD mode’, or limited-slip differential mode. That’s technically true but massively confusing because it’s not an LSD, it just acts a like one in some respects, and most 86/BRZs have a true, mechanical limited-slip differential in the form of a Torsen unit on the rear axle. Subaru’s term is TCS Limited Slip Device. Except it’s not a device, it’s just software. I did mention the names were confusing. | | ABS | Anti-lock brakes. Detects that a wheel is about to lock and momentarily reduces brake pressure on that wheel to prevent the wheel locking up. Both Subaru and Toyota agree on this name. | | EBD & EBA | Electronic Brakeforce Distribution. Cars are naturally designed to brake the front wheels more than the rear for safety reasons. Unfortunately, this means there is unused braking capacity on the rear wheels. EBD distributes braking force between all four wheels for maximum braking efficiency. Plain ABS just stops a wheel locking. There’s also EBA, Electronic Brake Assist and this helps you apply the brakes hard in an emergency by detecting how quickly your foot moved from accelerator to brake and if you don’t push the pedal all the way to the floor, it’ll help you. Both Subaru and Toyota agree on this name. |

Decoding the Rays Wheels SKU is useful since it allows us to synthetically re-create SKU numbers that may (or may not) have existed in the past, in lieu of an authoritative source of historical SKU numbers, so we can search for these numbers on eBay or elsewhere, where we may find rare wheels that others may not have found.

The information encoded within the SKU number contains details of the wheels’s model, generation, wheel size, and color.

Each letter in the SKU designates a code:

| Code | Description | | :--- | :---------- | | model | Model in the Volk Racing model line | | size | Wheel width by height | | offset | Wheel offset | | PCD | Wheel PCD or bolt pattern | | color | Wheel color |

The Applied Model (also called a Chassis Code) is a 7-digit code number that is used by Subaru to identify a car’s specification, but unlike the Chassis Number or VIN, this does not uniquely identify an individual car. Almost all Subaru cars have the Applied Model stamped on a metal plate that can be found riveted to the top of the near-side strut tower, although some cars have the plate in one of the front door frames.

The information encoded within the Applied Model number contains details of the vehicle’s model, body type, engine type, gearbox, trim-level and period of production.

Each letter in the applied model designates a code:

| Code | Description | | :--- | :---------- | | series | Model in the Subaru lineup, e.g. Impreza, Legacy, Forrester | | body style | body style describes coupe, sedan, wagon, hatchback | | engine | engine type | | model year | the production year and month | | # of doors | number of doors | | trim | specific equipment package and accessories | | transmission | transmission type, e.g. manual or automatic and number of speeds |

Series Code

The Series code is the first letter, it tells you which model in the Subaru lineup it belongs to:

| Code | Model | | :--- | :---- | | A | Leone/Loyale | B | Legacy | | C | SVX | | G | Impreza, XV, Outback Sport | | F | Domingo | | K | Justy/Rex/Vivio/Sambar (Before 1998) | | N | Trezia | | R | Pleo, R1, R2, Stella | | S | Forester | | T | Sambar (After 1998) | | V | WRX | | W | Tribeca/Ascent | | Y | Exiga | | Z | BRZ |

Thus, the Impreza WRX starts with 'G'.

Body Style code

The second letter is the Body style code, it'll tell you if the vehicle is a sedan, coupe, wagon, etc.

| Code | Body style | | :--- | :--------- | | A, C, E, V | sedan | | M | coupe | | F | 5-door wagon | | H, R | 5-door hatchback |

Applied Model Code

The Applied model is the first-two letters combined, it is what people commonly refer to when trying to casually designate their vehicle:

| Years | Code | Model | | :---- | :--- | :------------ | | 1992 - 2000 | GC | sedan | | 1992 - 2000 | GM | coupe | | 1992 - 2000 | GF | wagon | | 2001 - 2007 | GD | sedan | | 2001 - 2007 | GG | wagon | | 2007 - 2014 | GH | WRX hatchback | | 2007 - 2014 | GR | WRX STI hatchback | | 2007 - 2014 | GE | WRX sedan | | 2007 - 2014 | GV | WRX STI sedan | | 2015 - 2021 | VA | WRX & WRX STI sedan |

Engine code

The 3rd-letter in the applied model code. For the WRX STI platform, the EJ207 was mostly commonly used in Japan, while the US got the EJ257.

| Code | Description | | :--- | :---------- | | 8, B | EJ207 2.0ℓ turbo WRX STi in all late WRX STi models (GC8, GDB) Turbo is a IHI VF28 or IHI VF29 (STi V.6 Type R & Type RA) | | A | EJ205 2.0ℓ turbo WRX in all 1999-2005 models | | 6, F | EJ257 - 2.5ℓ turbo in USDM WRX STi IHI VF48 |

Model Year

The 4th letter in the code, the model year is the date of production, often times these start the year prior to the marketed year. This is because production of a vehicle starts early, and sales follow.

A is the first year of the generation, B the second, etc. When the model changes generation, (e.g. Mean Eye to Bugeye), this letter is reset back to 'A'.

• A "Mean Eye" GC8 first year has a A, thus GC8A, which is 1992.
• A "Mean Eye" GC8 second year has a B, thus GC8B, which is 1993, etc.
• A "Bug Eye" GDB second year has a A, thus GDBA, which is 2000.
• A "Bug Eye" GDB second year has a B, thus GDBB, which is 2001, etc.

Number of Doors

The 5th letter is the number of doors on the vehicle. Simply put, the coupe has a code of 2, sedan 4, and wagon & hatch 5.

Trim Code

The 6th-letter is the trim code, which tells you which marketing package, equipment and accessories are included in the vehicle. This list is incomplete, if you know any others, please let us know.

| Code | Name | | :--- | :-------- | | 7 | type RA | | 8 | WRX | | D | STI Type R & Type RA | | E | STI |

Transmission Code

The 7th-letter is the transmission code, tells you if its a manual or automatic.

| Code | Transmission type | | :--- | :---------------- | | D | 5MT | | 4, P | E-4AT | | H | 6MT |

Examples

In the examples below, I didn't include the number of doors, trim, or transmission codes. Putting this all together, we can see a list of significant applied models:
