Why Choose Carbon Fiber Side Skirts?
Carbon fiber is one of the most popular materials in the automotive world, and for good reason. When it comes to side skirts, opting for carbon fiber offers several benefits:
1. Weight Reduction and Performance
One of the main reasons carbon fiber is favored in performance vehicles is its lightweight nature. Compared to stock plastic or fiberglass side skirts, carbon fiber significantly reduces weight, which helps in:
- Better acceleration
- Improved fuel efficiency
- Enhanced overall handling
2. Durability and Strength
Carbon fiber is known for its high tensile strength, meaning it can withstand more stress without cracking or breaking. Unlike polyurethane or fiberglass, which can be brittle or prone to damage, carbon fiber provides:
- Longer lifespan
- Resistance to environmental factors
- Higher impact resistance
3. Aesthetic Appeal
Let’s be honest—carbon fiber just looks amazing! The glossy, high-tech weave pattern gives your BMW E90 a sporty, aggressive look that stands out. Whether you’re on the streets or at a car meet, carbon fiber side skirts add that premium touch.
Compatibility with the 2007 BMW E90
Before purchasing carbon fiber side skirts, it’s important to ensure compatibility with your specific BMW 3-Series model.
Exact Fitment for E90 Models
The E90 refers to the sedan version of the BMW 3-Series from 2006 to 2011. Side skirts designed for this model will fit perfectly without the need for major modifications.
Differences Between E90, E92, and E93 Side Skirts
- E90 (Sedan) – Has a specific side skirt length and mounting points.
- E92 (Coupe) – Slightly different dimensions; E92 skirts may not fit an E90 properly.
- E93 (Convertible) – Similar to the E92 but may have slight fitment differences due to chassis reinforcements.
Always double-check compatibility before purchasing to avoid fitment issues.
