PRAZIS® RAZOR ACTIVE™ “TRACK SAVAGE” STAGE 2 SETUP | RASS

RAZOR ACTIVE SUSPENSION SYSTEM (RASS)

SHORT DESCRIPTION

A precision-balanced performance system. RASS (Razor Active Suspension System) by PRAZIS® in Stage 2 form delivers sharpened response, lightweight racing geometry, and electronically controlled damping for aggressive street and track performance.

FULL SYSTEM HIERARCHY — RASS PLATFORM

STAGE 1 — DAILY / STREET PERFORMANCE

Comfort-focused performance system designed for daily driving, canyon runs, and weekend track use. Softer strut valving, reinforced durability, and long-term reliability with low maintenance requirements.

STAGE 2 — “TRACK SAVAGE” PERFORMANCE BALANCED RACING GEOMETRY

The “TRACK SAVAGE” Stage 2 is the mid-level evolution of the RASS platform.

It bridges daily usability and full race aggression, delivering sharper chassis response, improved feedback, and lightweight racing geometry while maintaining controlled street drivability.

• Firmer struts than Stage 1
• Lightweight performance-focused construction
• Optimized racing geometry for handling precision
• Increased steering response and chassis feedback
• Tuned for aggressive street driving and track capability

Requires system refresh and calibration update every 6 months to maintain optimal damping performance and consistency.

Purpose: Street performance builds, canyon driving, track days, and balanced motorsport use

STAGE 3 — TOLOZA D1F1 FULL RACE SPEC

Maximum performance RASS configuration engineered for extreme motorsport. Hardest strut valving, highest response under load, and maximum chassis control at high G forces with advanced damping behavior.

RASS — RAZOR ACTIVE™ SYSTEM (ACE TECHNOLOGY)

The RAZOR ACTIVE™ Suspension System delivers real time chassis control through advanced electronics and motorsport grade engineering.

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 aggressive track mapping using 5 customizable presets
Semi-active electronic damping improves high-speed stability and corner control
Digital touchscreen ECU controller
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 precision coilover performance platform with full mechanical response.

R-ACE COILOVER SYSTEM INTEGRATION

The coilover system fully integrates ACE technology with external reservoir damping for precision tuning.

Stand-alone electronically adjustable R-ACE RAZOR ACTIVE™ Controller
Compatible with adjustable or fixed top mounts
Racing springs selected from multiple performance ranges
External reservoirs with high-speed and low-speed compression adjusters
Optional 3-way mechanically adjustable configuration available

ENGINEERING & CONSTRUCTION

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 race engineering, and hybrid suspension technology.

Only what wins.

Minimal. Relentless. Unmatched.
