DDMWorks Backbone Brace for Pontiac Solstice and Saturn Sky – Strengthen Your Ride with Precision Engineering
Unlock the full potential of your Pontiac Solstice or Saturn Sky with the DDMWorks Backbone Brace, the essential upgrade for improving your vehicle’s torsional rigidity and overall performance. Designed to address the inherent weakness in the center section of convertibles, this high-quality aluminum brace provides significant structural improvements for a more responsive, stable, and precise driving experience.
Why the Solstice and Sky need the DDMWorks Backbone Brace: Convertibles, by their very nature, have a weaker center section compared to modern sedans. The section height between the front and back of the door openings is the shortest on the car, creating a vulnerability in the chassis that can lead to unwanted twisting and bending. This is especially true for performance driving, where added power and dynamic forces can exacerbate chassis flexing, impacting handling and driving responsiveness.
The DDMWorks Backbone Brace is engineered to eliminate this weakness. By replacing the flimsy stock stamped steel piece with a rigid, high-strength 6061 aluminum backbone, you significantly improve the vehicle’s torsional rigidity, transforming the way your car handles corners, acceleration, and braking. The difference is immediate—your car will feel solid, responsive, and more planted on the road, even during aggressive driving.
Key Features:
Increased Torsional Rigidity: The DDMWorks Backbone Brace stiffens the "U" channel under your car, resulting in a 30% improvement over the stock setup. This upgrade helps the suspension work more efficiently, reducing unwanted twisting and flexing during spirited driving.
Enhanced Handling: After installation, you'll immediately notice how the car responds quicker to steering inputs, with faster reactions and a more solid feel through corners. This improves the driving experience, making the car feel more like an expensive performance vehicle.
No Harsh Ride: Despite its added stiffness, the Backbone Brace does not make the ride harsher than stock. Instead, it provides a more stable platform for your suspension to perform at its best, giving you a smooth, controlled ride.
Made from Premium 6061 Aluminum: Strong, lightweight, and durable, this material is ideal for increasing your car’s strength without adding unnecessary weight.
Variety of Options: Choose between the Base 1/4", Performance 3/8", and Race/Track 1/2" versions. The Race/Track version features cut-outs, allowing it to weigh the same as the 3/8" Performance version but with added stiffness, perfect for those pushing their car to the limit on the track.
Easy Installation: The kit comes with all necessary hardware for installation, including optional longer bolts for the 3/8" and 1/2" versions. Installation torque specs are 13-15 ft-lbs for a secure and proper fit.
