Strut Brace (Strut Tower Bar)
A strut brace is a bar that connects the tops of the suspension strut towers to reduce body flex during cornering.
What is Strut Brace (Strut Tower Bar)?
It is usually fitted under the bonnet between the front strut towers. Rear versions also exist. Its effect is greatest on older or more flexible bodies. Some performance models have a strut brace fitted from the factory.
How it works
Tying the towers together reduces movement between them under load, keeping suspension geometry more stable.
Why it matters for your car
Some braces block access to engine parts or the battery. Its effect on a modern stiff body may be hard to feel.
