Warranty Policy

Effective Date: January 1, 2026

Last Updated: August 21, 2026

This Warranty Policy applies to eligible products purchased directly from GSC Tuning (“GSC Tuning,” “we,” “us,” or “our”) through our official website, online store, or authorized sales channels.

By purchasing, installing, or using any product from GSC Tuning, you acknowledge that you have read, understood, and agreed to this Warranty Policy.

GSC Tuning sells aftermarket automotive products, including but not limited to carbon fiber components, front lips, side skirts, rear spoilers, exhaust systems, coilover suspension, headlights, taillights, brake kits, wheels, steering wheels, ECU software, window film, interior modification parts, custom products, and related automotive accessories.

Because many of our products are aftermarket, vehicle-specific, performance-oriented, custom-made, installation-sensitive, or intended for specialized automotive applications, warranty coverage is limited and subject to the terms below.

1. Warranty Coverage Overview

Unless otherwise stated on the product page, invoice, manufacturer documentation, or written communication from GSC Tuning, eligible products may be covered by a limited warranty against verified manufacturing defects, material defects, or product functional defects under normal intended use.

This Warranty Policy does not cover damage caused by improper installation, incorrect use, misuse, accident, racing, road hazards, modification, negligence, lack of maintenance, normal wear and tear, or conditions outside the product’s intended use.

Warranty coverage is not a satisfaction guarantee, fitment guarantee, installation guarantee, or performance guarantee.

2. Standard Warranty Period

Unless otherwise stated in writing, eligible standard products may carry a limited warranty of up to one (1) year from the original purchase date.

Certain products may have different warranty periods depending on product type, supplier, manufacturer, product page description, or written warranty terms.

If a product page, manufacturer policy, or written product-specific warranty states a different warranty period, that product-specific warranty period may apply.

GSC Tuning reserves the right to determine the applicable warranty period based on the product, brand, supplier, use condition, and applicable documentation.

3. Product-Specific Warranty Terms

3.1 Carbon Fiber and Exterior Body Components

Carbon fiber products, composite products, front lips, side skirts, rear spoilers, diffusers, splitters, hoods, trunks, bumpers, aerodynamic kits, and similar body components may be covered for verified manufacturing or material defects only.

3.2 Lighting, Electronic, and Electrical Products

Headlights, taillights, LED components, electronic modules, LED steering wheels, wiring-related accessories, and other electrical products may be covered for up to one (1) year against verified product defects, unless otherwise stated.

Installation alone does not automatically void the warranty. However, damage caused by installation, adjustment, removal, modification, or use is not covered.

Customers should inspect all products before installation.

Installation of a product may be treated as acceptance that the product was received in acceptable condition.

10. Performance Products and Vehicle Modification Risks

Performance products may alter the operation, reliability, handling, emissions, warranty status, or drivability of a vehicle.

For visible damage, cosmetic issues, missing components, delivery issues, or obvious defects, customers should report the issue within forty-eight (48) hours of delivery and before installation.

For functional issues discovered after installation, customers should stop using the product when safe to do so and contact GSC Tuning as soon as reasonably possible.

Failure to report an issue promptly may result in denial of warranty coverage.
