Seller's description

Specifications

Upgrade your 1:12 Losi NASCAR with this newly redesigned undertray system, now supporting multiple configuration options for scale builds, performance tuning, and even dual‑battery speed‑run setups. This precision‑printed tray adds a clean, finished look to the chassis while providing flexible mounting points for batteries and accessories.

The surface features a carbon‑texture appearance for a premium look. While it resembles carbon fiber, no real carbon is used — the effect is visual only. Every part is printed exclusively in PETG HF, chosen for its superior strength, impact resistance, and durability compared to PLA or standard PETG.

THREE SUPPORTED CONFIGURATIONS

Standard Configuration (Stock Nerf Bars)
⭐ Uses the factory Losi NASCAR side nerf bars
⭐ Fully compatible with the printed roll cages available in my shop
⭐ Ideal for scale realism and general running
⭐ Photos show pink upper connectors for demonstration only

Outboard Battery Configuration
🔧 Moves your battery fully to the left and as low as possible
🔧 Removes the stock nerf bar on one side
🔧 Relocates the factory Velcro strap
🔧 Improves weight bias for cornering
🔧 Roll cage compatibility: not supported in this configuration
🔧 Photos show yellow connectors for demonstration only

Dual Outboard Battery Configuration
⚡ Allows mounting batteries on both sides
⚡ Useful for speed‑run or high‑power builds needing extra capacity
⚡ Requires removal of both stock nerf bars
⚡ Roll cage compatibility: not supported in this configuration

WHAT’S INCLUDED
📦 1x Undertray (black PETG HF with carbon‑texture appearance)
📦 4x Upper Side Rail Brackets
📦 4x Upper Battery Hold‑Down Brackets
📦 2x Battery Hold‑Down Tension Blocks
📦 4x M3 x 10mm Countersunk Mounting Screws

Note: Listing photos show pink and yellow printed parts for clarity only. Actual product ships in all‑black PETG HF.

INSTALLATION NOTES
🛠 Attaches directly to the Losi chassis side rails
🛠 Uses included M3 hardware
🛠 No cutting or permanent modifications required
🛠 Choose the configuration that best suits your build style

MATERIAL INFORMATION
🧵 Printed ONLY in PETG HF for maximum strength and shock resistance
🧵 Carbon‑fiber appearance is texture only — no real carbon fiber is used

IMPORTANT NOTES
⚠️ RC car, chassis, body shell, and roll cage shown in photos are for display only
⚠️ Roll cage compatibility applies only to the standard configuration
⚠️ Adding this undertray will disqualify your car from the “Box Stock” class at most tracks. However, it can be removed in just a few minutes, allowing you to return to legal Box Stock configuration quickly and easily.
