What is a Strut Tower Bar?
A strut tower bar, also known as a strut brace or strut bar, is a component that connects the tops of the strut towers in a vehicle’s suspension. It helps to reduce chassis flex and improve handling by providing additional support and rigidity.
Why Should You Get a Strut Tower Bar?
- Improved Handling: Reduces chassis flex, providing better stability and cornering performance.
- Enhanced Stability: Helps maintain alignment and suspension geometry during aggressive driving.
- Reduced Body Roll: Provides additional support, reducing body roll during cornering.
- Aesthetic Appeal: Adds a performance-oriented look to the engine bay.
How Does a Strut Tower Bar Work?
Strut tower bars connect the tops of the strut towers, creating a more rigid structure and reducing flex. By providing additional support, they help maintain suspension geometry and improve handling. Key benefits include:
- Increased Rigidity: Reduces flex in the chassis, improving stability and handling.
- Maintained Alignment: Helps keep the suspension components aligned, providing more consistent performance.
- Improved Cornering: Reduces body roll and improves grip during cornering.
