FAQ
Frequently asked questions
Answers about the GR8LI6HT brand, GR86 / BRZ fitment, mats, ambient, underglow, the app, and delivery.
What is GR8LI6HT?
GR8LI6HT is a small Czech brand focused on in-house accessories and electronics for car people. The store is operated by EIGHTYSIX FORGE s.r.o.
Where can I buy products?
In the GR8LI6HT shop — open Shop, pick a product, and add it to the cart.
Do mats and ambient fit both GR86 and BRZ?
Yes. Second-gen Toyota GR86 (ZN8) and Subaru BRZ (ZD8) share the platform — our floor mats and footwell ambient are cut for both (2022+, LHD).
Are mats and ambient LHD only?
Yes. We currently offer left-hand drive (LHD) only for second-gen GR86 / BRZ.
Do you offer first-gen or RHD?
No. First generation (ZN6 / ZC6) and right-hand drive (RHD) are not in the lineup.
What style are the floor mats?
JDM checkerboard design mats in two colorways: grey-black with a taxi (orange-yellow) flame, and red-black with a blue flame.
Are they rubber all-weather mats?
No — these are interior design mats with precise OEM-anchor fitment, not TPE / WeatherTech-style liners.
How is the flame on the mats made?
The flame is handmade in Czechia — created by us. Colorway details are on the product page.
Does ambient lighting have an app?
No. Ambient is passive Plug & Play with no BLE and no app. One kit supports three colors (magenta, red, blue) — you set the color once by cutting a selector wire. Install via the A-pillar only, between an OEM connector.
Do I need to tear down the dashboard for ambient?
No. Only the A-pillar comes off. It plugs into original connectors — no harness cutting and no irreversible changes. It locks into the OEM mount on the passenger side.
How does ambient react to interior lamps? Any standby draw?
When the interior (DOM) lamps are on, ambient switches to white to match the cabin. At rest it draws zero current.
Are underglow neons road-legal?
No. They are not homologated for public roads in the Czech Republic or the EU. For Show Mode, motorsport, or off-road use only.
What is RGBCWWW and how are neons controlled?
RGBCWWW means full RGB plus cool and warm white (CW / WW). Control is over Bluetooth (BLE) in the GR8LI6HT app — modes, colors, effects, and brightness.
Does the app work on Android and iOS?
Android APK is available now. An iOS version is on the way.
Is neon install hard? Do they work with smart alternators?
Install is intentionally simple: LED strip orientation and wiring order do not matter — you configure everything in the app. The kit works on older cars with classic charging and newer ones with a smart alternator (ECU-controlled / variable charging voltage).
Do neons support welcome / bye animations and DOM reaction?
Yes. You can set welcome and bye animations on power-up and shutdown. DOM (interior lamp) reaction is also configurable in the app.
How do I pick neon kit size S / M / L?
By vehicle length. Exact mapping is still being dialed in — if you are unsure, email info@gr8li6ht.com and we will help.
When will my order arrive?
Each product shows availability (in stock / made to order / beta). Once Storefront Checkout is live, typical CZ delivery is 2–5 business days after dispatch.
Can I return items?
Yes — within 14 days for consumer distance sales if the goods are undamaged. See Returns & claims and the Withdrawal form.
Where are install guides?
In the Install guides section. A dedicated step-by-step ambient manual for GR86 / BRZ is also available in Czech.
