Meet The Crew

Charles Siritho

Founder | CEO

There are many important key factors that drive successful businesses. My name is Charles Siritho and I am a industry trailblazer. I am leaving my mark on the automotive industry. FFP’s customer service has become the industry standard 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 creates confidence when purchasing from us. We 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 my crew members have changed the aftermarket industry as a whole. 

In my down time, I thoroughly enjoy drifting and tracking our 2016 Ford Mustang Ecoboost. 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 ( or social media below.

Chase Hamilton 

Function Factory Performance General Manager / VIP Client Specialist 

Chase was born in Arizona, and while he grew up in 3 different states, found his way back to the desert to where he has been working at Function Factory since late 2020. He found a passion for cars in high school after picking up a 350z and learning to modify it himself, and fix it when it broke (which was pretty often). Shortly after the first Z, he picked up another 350z and taught himself how to swap a 6.0 LS into it. Fast forward to today, he is driving a 370z which is in the process of getting boosted with a single top mount turbo kit. He enjoys working on all types of cars, from hoopties to supercars, but his knowledge and passion lies within Nissan performance, Z’s, G’s, and GTR’s. Even when off the clock, he’s never truly off work. Feel free to reach out through any socials with any questions you have about upgrading your car.
