Lightweight carbon fiber strut brace for the compatible vehicles

The Seibon SB23HDCVR-R is a hand-laid 3K 2x2 twill weave carbon fiber over a fiberglass skeleton strut brace built specifically for the compatible vehicles. The UV-resistant gloss clear coat is factory-applied and ready to install. At up to 50% lighter than the OEM steel equivalent, it reduces unsprung weight for measurable gains in acceleration, braking balance, and cornering response.

Key Features

  • Chassis Rigidity: Ties the strut towers together to reduce chassis flex under hard cornering, improving steering precision and front-end feel.
  • Carbon Fiber Construction: Combines high tensile strength with minimal weight, adding structural benefit without meaningful mass.
  • Gloss Clear Coat: UV-resistant factory finish makes the brace a show piece in the engine bay.
  • Direct Bolt-On: Mounts to the OEM strut tower bolt locations using the existing hardware.
  • No Cutting or Drilling: Complete bolt-on installation using factory mounting points.
  • Seibon Fitment Guarantee: Test-fit and verified against the target vehicle.

Frequently Asked Questions

Is this a performance upgrade or mainly cosmetic?

Both. Carbon fiber strut braces provide measurable chassis rigidity benefits under hard cornering by reducing strut tower flex. They also look exceptional in the engine bay.

Does installation require any modification?

No. The brace bolts directly to the factory strut tower mounting points using the existing hardware.

Will this clear a cold air intake or aftermarket intake?

Fitment is designed for the OEM engine bay layout. Aftermarket intakes may affect clearance. Pre-fit before final installation.

What is the warranty?

Seibon provides a fitment guarantee and a 6-month limited clear coat warranty. Under the Magnuson-Moss Warranty Act, this product does not void your vehicle's factory warranty.

How much does it weigh?

Carbon fiber strut braces are significantly lighter than comparable steel braces, typically under 3 lbs depending on the application.

Can I install this at home?

Yes. A strut brace is one of the simplest bolt-on upgrades. Basic hand tools and a torque wrench are all that is needed.

Does this affect daily drivability?

No negative effects. Increased chassis rigidity typically improves steering feel and response with no drawbacks for street driving.

Is the carbon fiber strong enough for structural use?

Yes. Carbon fiber has an exceptional tensile strength-to-weight ratio, making it well-suited for chassis bracing applications. Seibon's construction is trusted by professional racing teams.
