Stage 1 " STRIKE FIRST " PRO. MECHINE is the entry point into the PRAZIS® performance suspension platform—but make no mistake, this system is far beyond a typical air ride setup.
Most DIY air suspension kits simply replace coil springs with air bags. PRAZIS® Stage 1 " STRIKE FIRST " PRO. MECHINE systems are engineered to work with your car’s suspension geometry, camber gain, roll center, and damping characteristics.
The result is a system that delivers approximately 20% better overall performance efficiency compared to typical self-built air suspension setups.
Instead of guesswork, you get properly matched dampers, correct bag sizing, optimized airflow, and suspension travel designed for real driving conditions.
Key Features
• Fully custom suspension built for your vehicle
• Motorsport strut bodies (QA1 / KW Suspension / Nitron)
• Custom PRAZIS® air springs engineered for load and travel
• Optional helper springs for extended performance range
• High-flow 3/8" airline system for faster response
• Air Lift Performance® or AccuAir® management integration
• Custom CNC mounts, adapters, and brackets
• Air tank and compressors included
• Polyurethane vibration isolators
Performance Focus
Stage 1 " STRIKE FIRST " PRO. MECHINE is ideal for:
• Performance street builds W. WICKED STIFF GEO!
• Track dayz and Track Nightz!
• Drift builds that perform!
• BMW enthusiasts with GRIT!
It’s clean, streamlined, simple straightforward, and properly engineered.
Not overbuilt. Not underbuilt. Just dialed in, to your cars Stoked Setup!
PRAZIS® CUSTOM RACING AIR SUSPENSION SYSTEMS
STRIKER Stage 1 • SAVAGE Stage 2 • D1F1 Stage 3
PRAZIS® CUSTOM RACING AIR SUSPENSION SYSTEMS
At PRAZIS®, we don’t build off-the-shelf suspension kits.
We build track weapons.
Every system we produce is 100% custom engineered and proudly made in the United States of America, designed specifically for the geometry, weight distribution, suspension travel, and performance demands of your vehicle. Think of it like a tailor-made racing suit or a custom pair of shoes—built exactly for the machine wearing it.
Unlike generic air suspension kits, PRAZIS® systems are engineered for performance first. We design around the science of chassis dynamics: camber curves, roll centers, weight transfer, suspension frequency, and damper response. When done properly, air suspension becomes more than ride height adjustment—it becomes a tunable performance platform.
Built With American & European Motorsport Components
PRAZIS® is committed to building suspension systems using United States and European manufactured components whenever possible. Our philosophy is simple: use proven motorsport engineering from regions known for producing the highest quality racing hardware in the world.
All PRAZIS® suspension offerings and core components are 100% proudly manufactured in the United States, supported by select European motorsport suppliers whose engineering standards align with ours.
Every PRAZIS® system is built around premium motorsport strut bodies from manufacturers such as:
• QA1
• KW Suspension
• Nitron
These are paired with custom-built PRAZIS® racing air springs, optional helper springs, and high-flow 3/8” airline systems to maximize airflow, response speed, and durability.
Our kits integrate with Air Lift Performance® or AccuAir® management systems, and include custom CNC machined adapters, fittings, mounting plates, and reinforced brackets designed specifically for your chassis.
Each PRAZIS® suspension system includes everything required for a complete performance build:
• Custom racing air struts
• Custom built air springs
• Optional helper springs
• 3/8" high-flow airlines and fittings
• Air Lift Performance® or AccuAir® manifolds
• Air tank and compressors
• Custom CNC adapters and mounting plates
• Polyurethane isolators for vibration control
• Reinforced mounting brackets and hardware
Every system is built to order, meaning no two PRAZIS® kits are exactly the same.
Because real performance requires real engineering.
The PRAZIS® Legacy
PRAZIS® has been building race-ready suspension systems since 1998. Our early work supported underground car clubs and performance communities such as the Autobots, while collaborating with performance-driven shops like Spreewell Racing. Over the years, PRAZIS® systems and components have also been supplied to respected performance shops including TNL Auto Shop & Performance and 213Motors / 213Racing.
Today, PRAZIS® has sharpened its focus toward BMW performance and racing platforms, working directly with builders and teams to develop suspension systems specifically engineered for these chassis.
PRAZIS® Racing Network & Partners
PRAZIS® works alongside a global network of racers, builders, car clubs, and performance communities who share the same commitment to precision engineering and real motorsport performance. Current collaborators include M3646, FNSAVAGES Racing, BMWAF, the worldwide MADDRIFT Team from Poland, The Fucking Savages Race Team from Los Angeles, California, and the Striker Crew Car Club.
Industry partners supporting PRAZIS® builds include Tier1Euro, Turn14 Distribution, Supertech Performance, Universal Air Suspension, AVS, Air Lift Performance®, and AccuAir®, along with additional performance manufacturers and motorsport suppliers that continue to support the PRAZIS® ecosystem.
Built for the Track and Real Drivers Not for Clowns in Clown Cars
PRAZIS® systems are built for the track and for real drivers who understand performance. These suspension systems are not designed for gimmicks, trends, or show cars that never see real driving. PRAZIS® builds purpose-driven suspension engineered for drivers who actually push their machines and expect their equipment to perform.
One thing that makes PRAZIS® different is how we work with our customers. We do not sell generic, off-the-shelf kits. Instead, PRAZIS® works directly with each customer, builder, or race team to design a suspension system tailored to their specific vehicle, performance goals, and driving style.
Our goal is simple: to deliver the highest-performance air suspension systems possible while offering the best value within the performance racing category.
Experienced drivers understand that the difference between a good car and a seriously fast car usually comes down to how well the suspension is engineered. That is exactly what PRAZIS® has been perfecting since 1998.
Clean. Precise. Fast. Exactly how a race car should feel.
PRAZIS® Custom Racing Air Suspension
At PRAZIS® we don’t sell off-the-shelf kits. We build track weapons . Every system is 100% custom-engineered and made in the USA , tuned for your car’s weight geometry travel and performance needs. Think custom race suit meets hand-stitched shoes made for your whip.
We dial in full chassis science camber curves roll centers weight transfer suspension frequency and damper response. Properly set up air suspension is more than ride height it’s dynamic control street to track domination pure stoke .
Built With USA & EU Motorsport Parts
We only roll with top-tier USA and EU components QA1 KW Nitron Air Lift AccuAir. Every kit comes with custom CNC mounts high-flow airlines air tanks compressors poly isolators and everything to make your ride stiff fasta and unstoppable .
Every kit is built-to-order no copy-paste no BS. Real performance takes real engineering.

NOTE :
All PRAZIS® Custom Racing Air Suspension Systems require a non-refundable deposit of $1,500 to begin the build process. This deposit covers the time and resources our staff invests in collecting and analyzing vehicle-specific data, which may include travel, dyno rental, and other associated costs. If, at any time, you cancel the project or pull out of the order, the deposit is non-refundable, as it only represents a small portion of the actual expenses incurred. Once data collection is complete, full payment is required to proceed with the build. The initial $1,500 deposit will be applied toward the total cost of your kit if you complete the purchase. Final pricing may vary depending on the options and configuration selected within your setup’s stage budget.
If you represent a professional race team and already have your vehicle geometry data and know the specifications you want, we can proceed directly to manufacturing after reviewing your data and obtaining sign-off from our engineers to ensure compliance with North American safety standards.
All PRAZIS® offerings are for professional installation and use only and are not recommended for commercial or public road use. All parts are sold under the strictest of guidelines to maintain quality, safety, and performance standards.
