The factory crew

The crew at Function Factory Racing brings over 50 years of combined industry experience to the table. From digital media, fabrication, and high performance driving. The individuals that make up our crew are unique in ways that make us all movie characters of some sort. Each one of us has our own ridiculous story of how they have come to this point. We can all promise you one thing though, Function Factory Racing promises to deliver you the best DAMN experience possible. When we say we’re going to do the DAMN thing, we mean it.

Charles Siritho

CEO & Founder | Lead Instructor

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. 

Nyla Kramer

UAD Client Relations

My name is Nyla, I’m an avid car enthusiast who is always wanting to learn more about the world of motorsports. I was born in Portland and raised in Scottsdale. I grew up in a car-loving family, my dad is an exotic car collector who loves specifically Lamborghini’s and Aston Martins. I am very fortunate to have had a car upbringing and to have driven the majority of supercars on the market today. Thanks to Charles and FFP, I have learned more about American muscle cars, to be driven and dedicated to informing and selling people some of the coolest car mods on the market, and how to drive on a track. A lot of our weekends are spent at the track, where I have learned car control and how to drive on a track fast, safely, and efficiently. I have recently gotten into JDM cars and am currently building a Nissan RPS13 240SX with Charles’ help. My goal is to build this car, get better at drifting, and eventually drive in small drift events as a hobby. A very expensive hobby I have learned. As for my daily life, I mainly work and do car events on the weekends. I daily drive a 2014 C63 AMG 507 edition, it is tuned, and has an exhaust. My dad had a C63 in 2008 right when they came out and I was mesmerized by the car’s looks and sounds, since then it has been a goal of mine to own one and I was fortunate enough to have completed that goal in Nov 2020. My plan for the future is to get more into AMGs, specifically an AMG GTR, track driving, drifting, and to continue building the 240.
