What material is used and how will it perform over time?

This spoiler is manufactured from premium ABS plastic chosen for its toughness and temperature tolerance.

How easy is installation and what tools or materials are needed?

The spoiler installs using supplied automotive double-sided tape, allowing for a relatively quick, non-drilling attachment when properly aligned. While the kit includes necessary adhesive, professional installation is recommended for perfect alignment and edge sealing. Surface preparation and careful positioning are essential to achieve a secure bond.

• Attaches with double-sided automotive tape — no drilling required.
• Recommended tools: cleaner, isopropyl alcohol, alignment tape, and a heat source for tape activation.
