BBi StreetCup harness bar.
with standard powder coat colours.



BBi StreetCup Harness bar for the 992 Carrera is designed to fit perfectly within the vehicle. Unique to BBi Harness bars, the main hoop is contoured to the headliner and runs close to B pillars. This improves rear view visibility and matches the interior geometry. All the X sections are symmetrical for visual balance. The forward harness bar mounts attach to the chassis and the rear points bolt to the shock tower. The horizontal bars on the rear section are set a perfect height for race harnesses.

Utilizing 3D scanning, precision manufacturing and fixturing and stringent QC - this is a bolt-in product. The 4-piece design allows for easier installation with reduced interior disassembly.

As always, StreetCup harness bars are custom coated per order and we are able to match many OE colours. Please allow for turn-around time for bespoke powder coating. Usual turnaround is 1 week for common colours.

Constructed using 50+ layers of aerospace-grade dry carbon fiber and an AI-optimized uni-directional fiber layup, this roll cage achieves a groundbreaking balance of ultra-lightweight strength — weighing just 12.8 kg versus the manufacturer-standard 14.2 kg equivalent. The result is the strongest, safest, and most precisely engineered roll cage available for modern Porsche GT models.

What Makes the SilverRocket Carbon Roll Cage Unique?

1. Seamless Carbon Fiber Weave Texture
Unlike conventional roll cages with visible joining seams, SilverRocket’s proprietary carbon manufacturing process creates a flawless, continuous weave, even across complex curved surfaces — a first in the industry.

2. TÜV Tested & FIA 253 Certified
Tested by TÜV SÜD, this roll cage exceeds FIA 2023 Safety Requirements (Appendix J – Article 253) by 4.4x, withstanding a crushing 23,656 kg (52,152 lbs) — surpassing global racing standards by a significant margin.

3. Fully Symmetrical Structure for LHD & RHD Vehicles
Engineered for true global compatibility, the SilverRocket roll cage provides identical protection for both left-hand and right-hand drive models, ensuring uncompromised safety for every driver.

4. Enhanced Rear Visibility & Usability
The lowered curved rear structure ensures zero rear vision obstruction, while the enlarged central tunnel allows easy access to the rear seat — perfect for drivers using the area for storage during track days.

5. AI-Optimized Uni-Directional Layup
Using advanced AI topology mapping, SilverRocket precisely aligns every carbon fiber layer for maximum load-bearing strength while minimising weight.

6. Integrated Mounting System for Rapid Installation
The roll cage’s integrated mounting system simplifies installation, improving alignment and reducing fitting time without compromising rigidity or performance.

Why Do Conventional Roll Cages Fail?

Traditional metal or multi-piece carbon roll cages often suffer from issues like:

• Visible seam joins that create weak points under stress.
  
• Corrosion or micro-cracking in metal-based systems.
  
• Uneven protection between LHD and RHD variants.
  
• Poor rear visibility due to oversized upper bracing.
  
• Excess weight affecting center of gravity and balance.

The SilverRocket Seamless Carbon Roll Cage solves all of these — combining AI-engineered topology, TÜV-certified safety, and perfectly symmetrical geometry to deliver the most advanced roll cage solution ever produced for the Porsche 992 GT platform.

Why Upgrade to a SilverRocket Seamless Carbon Fiber Roll Cage?

Upgrading to a SilverRocket roll cage provides Porsche GT owners with an immediate performance and safety edge. Its cutting-edge materials and engineering deliver unrivalled protection, improved handling stability, and reduced body flex — all while maintaining a clean, race-ready aesthetic.

Key Benefits:

• Weight reduction from 14.2 kg to 12.8 kg.
• TÜV and FIA-certified impact protection exceeding requirements by over 400%.
• Symmetrical protection and flawless weave finish.
• Improved visibility and rear seat accessibility.
