Lightweight, Triangulated Option
Our lightweight strut braces are available in a choice of single bar and triangulated styles. These strut braces are an excellent and economic solution for reducing strut tower flex.
Our more sophisticated QuickChange Strut Brace System may be of interest if you seeking additional features.
Triangulation bests the single bar braces by increasing rigidity. Traditional braces tie strut towers together force them to move in parallel, sharing the cornering force of the loaded tire over both towers to reduce flex. Triangulation locks the towers rigidly in place to maintain camber settings – even through high G corners.
• Strengthens strut towers to minimize chassis flex
• Easy bolt-on installation
• 1978 to 1989 cars require one hole to be drilled for the triangulated brace
• Cars prior to 1978 already have the hole in place
Made from sturdy aluminum tubing our braces are tapered and terminated with quality rod-end fittings for precise alignment, adjustability and rigidity. Adjustable pre-load allows you to dial in a bit of extra camber if desired. All required mounting hardware is included.
Fit and finish make these braces as attractive as they are functional.

Expandable, quick removal and installation.
Our unique QuickChange™ strut-brace system is available in two configurations and is expandable to grow with your needs. Quick release pins let you remove or reconfigure in minutes.
Expandable – Start with a single-bar strut tower brace and later scale up with triangulation or even a full-blown 935 X brace, the system is completely upgradable. Grow or reconfigure your brace to match your changing needs for chassis rigidity, storage capacity, and budget.
Quick Release – Tubes are secured with quick release pins, each held in place by a detent ball. Quick Release pins allow fast, tool-less removal for service access or expanded stowage capacity.
Build Quality – Truly awesome appearance matches the functionality. Oversized aluminum tubing has a beefy, stout appearance yet remains lightweight and has a purposeful frosted anodize finish. CNC machined billet aluminum clevis ends are anodized a tasteful burgundy color.
Easy Bolt-in Installation – All configurations are completely bolt-in, no welding required. 1978-1989 cars drill one hole for triangulation option. 1966-1977 already have the hole.

Four Configurations
Start with any configuration, all can be fully upgraded by simply adding components. No throwaways! And all are quickly and easily removed when necessary with the quick-release pins.
Single Bar – The foundation of the system, the single bar connects the strut towers together for reduced flex.
Triangulated– Triangulation locks the towers even more rigidly in place to maintain camber settings – even through high G corners.
935 X Brace – Inspired by the chassis braces used on 935 race cars, the X brace increases chassis torsional rigidity. Completely bolt on, it attaches to the camber plates and the front corners of the trunk.
935 X Triangulated – The most rigid brace available, this configuration adds the triangulated member to the 935 X brace and is the complete QuickChange X Brace solution.

Porsche Motorsport Strut Braces | Design911 High-Performance Chassis Reinforcement
Strut braces are a vital upgrade for any Porsche involved in motorsport, spirited road driving, or performance tuning. They reinforce the vehicle’s suspension structure, maintaining precise chassis alignment under heavy cornering, braking, and acceleration. Whether fitted to a classic 911 or a modern Cayman GT4, these precision-engineered components enhance rigidity, stability, and steering response.
At Design911, we supply a premium range of strut braces and chassis reinforcement bars designed for strength, lightness, and exact fitment. Manufactured from high-grade aluminium, carbon fibre, and steel alloys, each brace offers exceptional torsional stiffness without unnecessary weight gain. Ideal for track-day setups, motorsport preparation, or performance restoration, our collection ensures your Porsche handles exactly as intended.
What Do Strut Braces Do?
Strut braces link the suspension towers together to reduce chassis flex, ensuring consistent handling characteristics even under high load.
Core Functions:
• Increase chassis stiffness and reduce body roll.
• Maintain precise suspension geometry during cornering.
• Improve steering accuracy and feedback.
• Reduce stress and movement in upper suspension mounts.
• Enhance overall driving stability and predictability.
By reinforcing the front or rear suspension structure, strut braces create a more connected, confident, and performance-focused driving experience — both on road and track.
Why Do Strut Braces Fail or Degrade?
Over time and through aggressive driving, strut braces can lose effectiveness due to fatigue, corrosion, or damage from improper installation or accidents.
Common Causes of Failure Include:
• Metal fatigue from repeated torsional loads.
• Corrosion or cracking in alloy or steel construction.
• Worn joints or mounting hardware causing flex or noise.
• Impact damage from track incidents or suspension movement.
• Substandard aftermarket materials lacking proper reinforcement.
When a strut brace fails or weakens, suspension alignment suffers — leading to reduced handling precision, unpredictable cornering, and compromised safety.
Why Replace or Upgrade Your Porsche Strut Brace?
Upgrading to a modern performance-spec strut brace ensures your Porsche maintains its optimal chassis integrity and handling balance.
Key Benefits:
• Restores and enhances chassis rigidity.
• Improves cornering stability and steering response.
• Prevents tower flex and suspension misalignment.
• Available in lightweight aluminium, carbon fibre, and reinforced steel.
• Precision-engineered for Porsche 911, Cayman, Boxster, and 718 models.
• Essential for motorsport, track-day, or high-performance road setups.
Design911’s Porsche strut brace range combines engineering accuracy, lightweight construction, and motorsport-proven performance — ensuring the best driving dynamics and long-term reliability.
