Record-Breaking Season: Paul’s Automotive Engineering Dominates with AMB Aero
Cincinnati-based racing team shatters track records and claims triple national championships with comprehensive AMB Aero aerodynamic solution
The Challenge
Paul and Brian Faessler of Paul’s Automotive Engineering in Cincinnati had built an incredibly fast Mustang race car, but they knew that to compete at the highest levels of time attack and time trial racing, they needed a complete, integrated aerodynamic solution. Their goal was ambitious: win multiple national championships and set track records across different racing series.
The Solution
AMB Aero worked closely with Paul’s Automotive Engineering over multiple seasons to develop and implement a comprehensive aerodynamic package specifically designed for their Mustang. The partnership involved:
- Custom CFD-designed splitter – Engineered for maximum front downforce
- Rear diffuser and side skirts – Integrated underbody aerodynamics
- High-efficiency rear wing – Balanced rear downforce
- Front fender canards – Final touch for optimal aero balance
The development process was iterative and collaborative, with continuous technical consultation and refinement between AMB Aero’s engineering team and Paul’s Automotive Engineering.
The Results: A Historic 2025 Season
The 2025 racing season delivered results that exceeded even the most optimistic expectations.
Grassroots Motorsports Ultimate Track Car Challenge / SCCA Time Trial Nationals
- Overall Championship win – Brian’s 3rd UTCC overall championship
- DEMOLISHED the overall SCCA/UTCC track record at Pittsburgh International Race Complex by a staggering 7 SECONDS – one of the largest margins of improvement in time attack history
- The front canards produced so much downforce that in just 2 laps (running on low boost), they literally pushed the splitter down hard enough to wear through the Delrin pucks and pull the center support cables through the splitter
- Had to detune the car mid-competition due to lack of competition – added front spring rates and more rear wing, kept it on low boost, and still dominated
NASA National Championships
- Three National Championships: American Iron Extreme (AIX), Super Unlimited GT (SUGT), and Time Trial GT (TTGT)
- Three National Championship track records in all three classes
- Seven regional first-place finishes
- Eight regional track records
The Most Dominant Performance of the Season
At the NASA Championships at Ozarks International Raceway, competitors launched an unprecedented protest campaign against the car’s legality:
- Friday: 14-item protest – 3 hours in impound → 100% LEGAL
- Saturday: 6-item protest – 4 hours in impound → 100% LEGAL
- Sunday: Executive appeal board review (4 more items) – 1 hour in impound → 100% LEGAL
After surviving 8+ hours of technical inspection across three days, Brian rolled out for Saturday morning warm-up and shattered the track record by over 1 second on just his SECOND LAP. The message was clear: this wasn’t about finding an advantage in the rules – it was about engineering excellence and driving skill.
The Partnership
“Thank you very much for the help in improving the car to this point,” said Brian Faessler after the record-breaking UTCC performance. “The canards working so well they’re dragging the splitter – now THAT is the kind of problem we love to have!”
The collaboration showcases AMB Aero’s commitment to working closely with customers through every stage of development, from initial CFD analysis to on-track refinement and continuous technical support.
Why It Worked
The success of Paul’s Automotive Engineering demonstrates several key principles of AMB Aero’s approach:
- Integrated Design – Every aerodynamic component was designed to work together as a complete system
- CFD-Validated Performance – Computational fluid dynamics ensured optimal airflow management
- Ongoing Technical Support – Continuous consultation helped maximize the package’s effectiveness
- Real-World Testing – Iterative development with track feedback refined the final package
The Bottom Line
With AMB Aero’s complete aerodynamic package, Paul’s Automotive Engineering achieved:
- 3 National Championships in a single season
- 11 track records (3 national, 8 regional)
- 7 SECONDS faster than the previous SCCA/UTCC overall track record
- Broke a track record on his 2nd lap after surviving 8+ hours of technical protests
- 100% technical compliance – vindicated through multiple scrutineering sessions
- So much downforce they had to detune mid-competition due to lack of worthy competition
“When you break a track record by 7 seconds and competitors can’t find anything illegal after three separate protests, that’s the definition of engineering dominance,” noted AMB Aero’s Director Andrew Brilliant. “The highest praise a car and team can receive is a protest you survive – that means you aren’t just fast, you are so fast they don’t even think it’s possible.”
