LAS VEGAS, Nev. — Sigma Performance Services announced changes to its leadership structure, including a separation from former director of competition Preston Peltier. The team said the changes would create opportunities for staff and expand support for its customers.
Over several years, SPS expanded from a local Las Vegas team to include national-level competition and high-performance services for racers across the Western United States. Peltier was among the people who helped that growth.
SPS said its track participation and customer support would continue, including the TMI No. 25 and No. 21 SRL cars, Jim Wulfenstein in the No. 12 and the No. 54 SPS house car.
The team will also maintain its affiliation with Kasey Kleyn’s Madera Jr. Late Model team and expand its support and participation in the SRL Pro Late Model Series and Las Vegas Motor Speedway’s Pro Late Model division.
We are very proud of the progress and success that was made during our association with Preston, and we will continue to work together to support each other under our own independent paths.
This change really provides expanded opportunities for everyone involved to refine the practices that have work well in the growth and success of SPS, while providing opportunities for all individual to pursue their own vision of how to provide an expanded platform of services to the racers around the Country.
