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.
QuickChange Strut Brace Video
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.

Integrated Monoball 3 Point Strut Brace - Rennline has designed a new 3-point strut brace specifically to work with the new Rennline front monoballs and create an integrated front suspension system unavailable anywhere else on the market. The new 3-point strut brace bolts directly to the tops of the front monoballs, locking exceptional rigidity into your front suspension and dramatically reducing camber changes in hard cornering and braking. Unlike other 3-point strut braces which anchor to flimsy trunk sheet metal, the diagonal bar of the Rennline brace bolts to the mounting studs used to attach the brake booster, which is one of the strongest locations on the front of a 911. For 911's with power brakes, the Rennline intergrated monoball strut brace is truly a bolt-in system, requiring no drilling. Installation of these strut braces will not change your alignment settings. Both upper and lower bars are fully adjustable, allowing you to set desired pre-load, and manufactured out of aircraft-quality aluminum and TIG welded stainless steel brackets. The complete assembly weighs only 2.6 pounds.

Rennline now offers these mounts for those dedicated to building the ultimate classic 911. These strut tower braces are of similar design to the units we have been offering for years, but take them to a new level of strength and effectiveness.
These braces are precision cut and bent in house, then dimple dyed for the ultimate in strength and rigidity. Once welded to the strut tower, they will not only provide an ideal place for mounting a strut tower brace to but they will increase the strength and rigidity of the entire tower.
The package is rounded out with one of our fully adjustable, spherical end strut bars to bolt between the brackets. Combined, this setup will provide the ultimate in stiffness and performance, ensuring optimal suspension geometry and steering feel under the most stressful of conditions.

Strut Brace
Chassis stiffening devices such as a strut brace adapt to the OEM suspension turrets on Porsche models and help to reduce chassis flex, aiming for more consistent steering feel and response on the road or track.
At Design911, we supply a wide range of strut brace options for Porsche models, from discreet road setups to track-focused hardware, so you can match the installation to how your car is used.
Why do Porsche Strut Brace matter?
A strut brace ties the suspension towers together to resist flex as loads pass through the chassis. On Porsche models this can help the front or rear of the car feel more tied together, especially when combined with other suspension work. Many owners choose a brace as a finishing touch once dampers, bushes and geometry have been refreshed, or when preparing a Porsche for more enthusiastic road or occasional track use.
- Support a more tied-together feel across the front or rear of the car when loaded
- Complement other suspension upgrades and geometry work
- Provide an additional tuning option for fast-road or track-focused builds
- Add a purposeful, motorsport-style look to the engine bay or luggage area

When should you review or replace your Porsche strut brace?
Checking strut brace installations periodically helps you confirm that fixings remain tight, clearances are still correct and the brace continues to suit how your Porsche is used. Although a brace is generally an upgrade rather than a wear part, it still needs to be installed and maintained correctly.
- You are refining a suspension upgrade and want more consistent front- or rear-end feel
- The car is used enthusiastically on twisty roads or for occasional track days
- You notice interference, rattles or contact marks around an existing brace
- You are carrying out wider suspension work and want the chassis setup to feel cohesive
If any of these apply, it is a good time to review your strut brace options and ensure anything fitted is in good condition and correctly installed so your Porsche stays dependable and enjoyable to drive.
