FULL SYSTEM HIERARCHY — RASS PLATFORM

STAGE 1 — “STRIKE FIRST” DAILY PERFORMANCE SYSTEM

The “STRIKE FIRST” Stage 1 is the foundation of the RASS ecosystem.

Built for everyday driving, it focuses on comfort, durability, and controlled performance while still maintaining the adaptive intelligence of RAZOR ACTIVE™ by PRAZIS®.

This is the most forgiving and longest-lasting configuration in the lineup, designed for drivers who want performance capability without sacrificing daily usability.

• Softer strut valving for comfort and compliance
• Reinforced hardware for long-term street durability
• Stable damping under high-speed road conditions
• Balanced chassis control for real-world driving
• Minimal maintenance, long-term reliability

Stage 1 gives control for daily life, street canyon driving, and weekend track fun. It remains highly responsive under load while maintaining comfort and durability for set it and forget it long-term ownership.

Purpose: Daily driving, canyon roads, weekend track use, long-term reliability

STAGE 2 — “TRACK SAVAGE” PERFORMANCE BALANCED RACING GEOMETRY

Mid-level performance system focused on sharper response, lightweight geometry, and increased chassis feedback for aggressive street and track use. Requires periodic calibration updates every 6 months.

STAGE 3 — TOLOZA D1F1 FULL RACE SPEC

Maximum performance RASS configuration designed for professional motorsport use. Hardest strut valving, highest response under load, and maximum chassis control under extreme G forces.

RASS — RAZOR ACTIVE™ SYSTEM (ACE TECHNOLOGY)

The RAZOR ACTIVE™ Suspension System delivers real time chassis control through advanced electronic damping and precision mechanical design.

SYSTEM CAPABILITIES

Adjust damping level of front and rear axle independently in 5 positions
Adjust roll and pitch control independently in 5 positions
Switch between comfort and performance modes using 5 customizable presets
Semi-active electronic damping improves stability under load
Digital ECU controller system
Wireless app control coming soon
Unlimited lifetime mapping updates
Up to 2 inches of instant front lift via integrated air cup system

When lift is inactive, the system functions as a stable, comfort-oriented performance suspension platform optimized for daily use.

SIGNATURE LINE

Underdog Built. Engineered to Win.

In 2004, Samuel Toloza was surrounded in Najaf during the Iraq War. Out of ammo, his last weapon was a 3 inch switchblade.

He didn’t fold. He held the line.

That same mindset drives RAZOR ACTIVE™ by PRAZIS®, built in Los Angeles on adaptive damping, coilover engineering, and hybrid suspension technology.

Only what wins.

Minimal. Relentless. Unmatched.
