Description


The SAFETY21 ASN Roll Cage VO (Vehicle Option) Reinforcement Bars are advanced, competition-focused structural upgrades designed to integrate directly with the certified roll cage. These optional bars provide targeted increases in chassis stiffness and suspension point rigidity, translating to sharper steering response, improved front-end stability, and more precise handling under extreme loads. Like the main cage, these are official homologation options (VO) requiring certification application.
Product Highlights
🏗️Â Advanced Structural Integration with Certified Cage
These bars are engineered as official Vehicle Options (VO) for the SAFETY21 ASN-certified roll cage. They bolt or weld directly to the main cage structure, creating a fully integrated safety and stiffness matrix that far exceeds the capabilities of a standard cage alone.
⚡Â Targeted Performance Enhancement
Each bar addresses a specific chassis dynamic:
-
VO Option 1 – Front Suspension Extension Bar (Blue): Ties the front suspension strut towers/areas directly into the main cage structure. This dramatically increases front-end torsional rigidity, reducing flex for sharper turn-in, improved steering feedback, and more consistent alignment under cornering loads.
-
VO Option 2 – Lateral Reinforcement Bar (Pink): Adds a high-level lateral cross-brace, further stiffening the cabin’s central structure. This enhances overall chassis cohesion and stability, particularly during high-G directional changes and side-loading.
🔧Â Competition-Grade Installation & Certification
-
Installation: Performed by the authorized SAFETY21 dealer during or after the main cage installation.
-
Certification: Adding these options requires a formal VO approval application (additional fees apply) to update the vehicle’s homologation papers, ensuring they are recognized as part of the certified safety structure.
🏁Â For the Ultimate Track & Race Build
These options are for competitors in the highest levels of time attack, circuit racing, or rally where maximizing chassis stiffness is a critical performance differentiator and where regulations allow for such reinforced cage designs.
Product Lineup & Specifications
VO Option 1 – Front Suspension Extension Bar:
-
Function:Â Connects front suspension points to main cage.
-
Benefit:Â Maximizes front-end rigidity and steering precision.
-
Product Code:Â 1C7-29W-RA1
VO Option 2 – Lateral Reinforcement Bar:
-
Function:Â Adds central lateral bracing to cabin structure.
-
Benefit:Â Enhances overall chassis stability and side-impact reinforcement.
-
Product Code:Â 1C7-29W-RA2
- Both bars can be installed together for the ultimate in chassis stiffness.
Critical Ordering & Installation Notes
⚠️Â Dealer Exclusive with Mandatory Certification
-
These cannot be purchased or installed separately from the main SAFETY21 ASN cage installation process through an authorized dealer.
-
Adding these options triggers a mandatory (and separate fee) VO approval application to the certifying body (ASN). This is essential for the vehicle to remain compliant with regulations.
🔩Â Professional Integration Only
Installation is complex, involving precise alignment and welding/bolting to the certified cage. This ensures structural integrity and maintains the homologation status of the entire safety system.
🎯Â Investment for Ultimate Performance
These bars represent the final step in creating an ultra-rigid competition chassis. The performance benefits are most apparent in vehicles with extensive aerodynamic downforce, slick tires, and professional drivers capable of exploiting the reduced flex.
