1. General Fitment Information

Product fitment information provided by GSC Tuning is intended for general reference only.

Although we make reasonable efforts to provide accurate product compatibility information, fitment may vary due to vehicle production differences, regional specifications, model-year changes, trim levels, factory options, prior repairs, aftermarket modifications, and installation conditions.

GSC Tuning does not guarantee that every product will fit every vehicle variation unless expressly stated in writing.

2. Customer Responsibility

Before placing an order, the customer is solely responsible for verifying that the product is compatible with the intended vehicle.

Customers should confirm all relevant vehicle information, including but not limited to:

· Vehicle make;

· Trim level;

· Engine type;

· Transmission type;

· Drivetrain;

· Body style;

· Production date;

· Region or market version;

If the customer provides incorrect, incomplete, or misleading vehicle information, GSC Tuning shall not be responsible for incorrect product selection, fitment issues, delays, return shipping costs, restocking fees, installation costs, or related losses.

3. Vehicle Variations

Automotive manufacturers may produce different versions of the same vehicle model depending on market, production date, trim, engine, drivetrain, and factory options.

For example, vehicles may differ between:

· U.S. market and international market versions;

· Rear-wheel drive and all-wheel drive versions;

· Different engine and exhaust configurations.

Such differences may affect compatibility.

Customers are responsible for confirming that the selected product matches their exact vehicle configuration.

4. Aftermarket and Modified Vehicles

Fitment may be affected by existing modifications or non-original parts installed on the vehicle.

These may include, but are not limited to:

· Aftermarket bumpers;

· Aftermarket fenders;

5. Product Images and Descriptions

Product images, renderings, videos, installation photos, and promotional materials are provided for reference only.

Actual product appearance may vary due to:

· Production updates;

· Supplier changes;

· Material differences;

· Lighting conditions;

· Photography angles;

· Screen display settings;

Product images may show optional accessories, painted examples, installed examples, or vehicles with other modifications not included with the product.

Customers should read the product description carefully before purchasing.

6. Minor Adjustment May Be Required

Many aftermarket automotive products may require professional test-fitting, adjustment, alignment, trimming, bracket adjustment, additional hardware, coding, programming, or body shop preparation.

A product is not considered defective solely because it requires:

· Minor adjustment;

· Test-fitting;

· Professional installation;

· Bracket alignment;

· Additional hardware;

· Trimming;

· Drilling;

· Coding;

· Programming;

· Calibration;

· Body shop work.

Aftermarket products may not install exactly the same way as original equipment manufacturer (“OEM”) parts.

7. Carbon Fiber and Exterior Body Components

Carbon fiber, composite, fiberglass, ABS, and exterior styling products may require professional installation and test-fitting.

Customers should test-fit all exterior components before painting, coating, drilling, cutting, wrapping, sanding, or final installation.

GSC Tuning is not responsible for paint costs, wrap costs, coating costs, body shop fees, labor costs, or related expenses if the customer or installer fails to test-fit the product before modification or installation.

Once a product has been painted, drilled, cut, trimmed, wrapped, sanded, modified, or installed, it may no longer be eligible for standard return.

8. Lighting and Electronic Fitment

Headlights, taillights, LED steering wheels, electronic modules, wiring harnesses, and other electrical products may require proper coding, programming, wiring, or compatibility verification.

Fitment or functionality may vary depending on:

· Factory lighting type;

· Vehicle options;

· Control modules;

· Coding;

· Wiring configuration;

· Regional software;

· Existing modifications;

· Previous electrical repairs;

· Vehicle battery condition.

GSC Tuning is not responsible for warning lights, error codes, flickering, coding requirements, programming requirements, water intrusion, or electrical malfunction caused by incorrect installation, wrong vehicle selection, modified wiring, incompatible vehicle systems, or third-party installer error.

9. Performance Product Compatibility

Performance products, including exhaust systems, intake systems, suspension components, brake kits, wheels, ECU-related products, and related upgrades, may interact with other vehicle systems or modifications.

Customers are responsible for ensuring that all components used together are compatible.

GSC Tuning does not guarantee compatibility with:

· Non-GSC aftermarket products;

· Custom fabricated parts;

· Previous modifications;

· Non-OEM software;

· Tuned vehicles;

· Damaged vehicles;

· Poorly maintained vehicles;

· Incorrectly installed components.

10. Wheels, Brakes, and Clearance

Wheel and brake fitment may depend on wheel size, width, offset, tire size, brake caliper size, suspension height, fender clearance, alignment settings, and vehicle modifications.

Customers are responsible for verifying clearance before purchase and before installation.

Rubbing, clearance issues, spacer requirements, rolling fenders, trimming, or alignment changes do not automatically indicate a product defect.

11. No Guarantee Based on Informal Advice

Any fitment assistance, product recommendation, compatibility suggestion, or technical guidance provided by GSC Tuning through email, phone, live chat, text message, social media, or other communication channels is provided as a courtesy only.

Such advice is based on information provided by the customer and information reasonably available at the time.

Fitment advice does not constitute a guarantee of compatibility, successful installation, legal compliance, or performance.

The customer remains responsible for final verification before purchase and installation.

12. Incorrect Product Ordered by Customer

If a customer orders the wrong product, wrong model year, wrong trim, wrong body style, wrong lighting version, wrong bumper version, wrong engine version, or wrong vehicle application, the customer is responsible for all related costs.

These costs may include:

· Original shipping;

· Return shipping;

· Replacement shipping;

· Restocking fees;

· Packaging costs;

· Carrier fees;

· Installation costs;

· Labor costs;

· Any applicable deductions under our Refund Policy.

Incorrect fitment caused by customer error is not considered a product defect.

13. Installer Responsibility

The customer and installer are responsible for verifying fitment before installation.

Installers should not install, modify, drill, cut, paint, wrap, sand, wire, code, program, or alter any product until compatibility and condition have been confirmed.

GSC Tuning is not responsible for installer error, lack of experience, refusal to install, incorrect installation, incorrect adjustment, damage caused during installation, or failure to verify fitment before installation.

15. Final Determination

GSC Tuning reserves the right to make the final determination regarding product compatibility, fitment issues, return eligibility, warranty eligibility, customer error, installation error, and available remedies.
