Polyurethane

Polyurethane (PU) is a flexible thermoplastic polymer increasingly favored for bumpers, lips, and lower body components that are prone to impact. Unlike rigid materials, polyurethane can absorb shocks and return to its original shape, reducing the risk of cracking or permanent deformation.

This makes it exceptionally well-suited for daily-driven AMG GT 63 S models navigating urban environments with speed bumps, curbs, and tight parking spaces. It also exhibits excellent resistance to weathering, UV rays, and chemical exposure. While it may not offer the same high-gloss finish as fiberglass or carbon fiber out of the mold, it accepts paint well and maintains integrity over time.

ABS Plastic

Acrylonitrile Butadiene Styrene (ABS) plastic is a popular material in OEM-style body kits due to its excellent balance of durability, thermal stability, and affordability. It is impact-resistant, easy to mold, and compatible with standard automotive paints and adhesives.

ABS maintains its shape across a wide temperature range, resisting warping in both hot summers and cold winters. It is commonly used in factory-installed aerodynamic kits and is a reliable choice for replacement parts. While not as lightweight or rigid as carbon fiber, ABS offers superior toughness compared to fiberglass and is less expensive than polyurethane or carbon fiber variants.

Aluminum

Aluminum is primarily used in structural or semi-structural components of high-performance body kits, such as hood vents, fender flares, or support brackets. Its high strength-to-weight ratio makes it ideal for reducing overall vehicle mass without sacrificing durability.

Naturally corrosion-resistant due to its oxide layer, aluminum performs exceptionally well in wet and salty environments, making it a smart choice for all-weather reliability. It can be polished, painted, or anodized for aesthetic versatility. While not typically used for full body panels due to forming complexity and cost, aluminum adds functional strength to key areas of the AMG GT 63 S’s exterior.
