Meet The Crew

Charles Siritho

Founder | CEO

There are many important key factors that drive successful businesses. My name is Charles Siritho and I’m here to leave my mark on the automotive industry. I believe that our customer service will become the industry standard moving forward. Our involvement in the automotive community continues to prove that we truly care about our customer basis. Extensive research and development of our products on the street and race track ensure confidence when purchasing from us. We will excel at digital marketing to the highest level from educational videos to informative instruction manuals that guide you step by step. I have been in this industry since the age of 18 and believe my crew members will change the entire aftermarket industry as a whole. 

When I’m not working (which is never) I thoroughly enjoy racing our 2016 Ford Mustang Ecoboost in California and local Arizona race tracks. I also have a 1989 Nissan 240sx that I encourage everyone to ride in to experience drifting at its best. 

Some interesting facts, I have flown over 170,000 miles in the year 2019 and travel extensively for work and play. Tokyo, Japan has been my favorite place thus far as I have dined at the best sushi restaurant in the world. I hope to revisit and drift the Ebisu circuit in the very near future. 

Feel free to always reach out to me via email (Charles@FFPerformance.co) or social media below.
