RSS Racing Overview
RSS Racing, also known as Ryan Scott Sieg Racing or Ryan Shane Sieg Racing, is an American professional stock car racing team that currently competes in the NASCAR O’Reilly Auto Parts Series. Founded in 2009 and headquartered in Sugar Hill, Georgia, the team is owned by Rod Sieg and Pamela Sieg and fields Chevrolet entries in the national series. The organization runs a multi-car operation anchored by the No. 39 of Ryan Sieg and the No. 28 of Kyle Sieg, with additional part-time entries across the No. 23, 29, 37, 38 and 93 car numbers. RSS Racing secured its first race victory in 2023 when Aric Almirola won the inaugural NASCAR Xfinity Series race at Sonoma, a watershed moment for the family-owned operation.
Across its history the team has competed in the NASCAR Camping World Truck Series, the ARCA Menards Series, the ARCA Menards Series East, the ARCA Menards Series West and the NASCAR O’Reilly Auto Parts Series. As of late 2025, RSS Racing maintains a technical alliance with the Haas Factory Team and has returned to Chevrolet as its manufacturer of choice. The team’s primary sponsors include CMR Construction & Roofing and SciAps, both of which have appeared prominently on the team’s flagship entries.
Founding and Organizational Origins
RSS Racing was established in 2009 by Rod Sieg and Pamela Sieg as a family racing operation based in Sugar Hill, Georgia. The team’s first competitive appearance came in the NASCAR Camping World Truck Series at the 2009 Copart 200 at Milwaukee, with the No. 39 truck driven by Ryan Sieg, son of owners Rod and Pamela. The early program was built around a small fleet of trucks and a tight-knit crew, with the Siegs using their own resources to assemble rolling chassis and source engines from respected builders in the garage area.
In its formative years, RSS Racing purchased rolling chassis from Kevin Harvick Incorporated until that organization shut down, and the team used Earnhardt Childress Racing engines during its initial Truck Series campaigns. The team also ran start-and-park entries in later years, including the No. 93 and other numbered trucks, to fund its primary effort. The business was structured as a modest family shop with a small full-time staff supplemented by part-time crew members at the track.
The team’s first foray into what is now the NASCAR O’Reilly Auto Parts Series came at the 2013 Indiana 250 at Indianapolis Motor Speedway, with the No. 39 fielded for Ryan Sieg. The early Xfinity program relied on Pro Motor Engines from 2013 to 2018 and the same rolling-chassis sourcing approach that had defined the Truck Series effort. By maintaining a conservative operating model and putting family members in the driver’s seat, the Siegs laid the groundwork for a multi-car operation that would eventually expand across multiple national series.
Growth Into NASCAR O’Reilly Auto Parts Series Competition
RSS Racing’s full-time move into the NASCAR Xfinity Series took shape in 2014, when Ryan Sieg committed to running the full schedule in the No. 39 and declared for the Xfinity rookie of the year battle. The team moved its engine supply to ECR Engines in 2019 and also began purchasing chassis from Richard Childress Racing during the offseason. By 2020, Ryan Sieg was running the No. 39 full-time with CMR Construction & Roofing as the primary sponsor, marking the team’s transition into a stable, sponsor-backed national program.
In 2021, RSS Racing expanded into a multi-car operation by adding the No. 28 for Kyle Sieg, the younger brother of Ryan, and the team also fielded the No. 23 in collaboration with Reaume Brothers Racing. From 2021 onward, the team began running Roush-Yates Engines-powered Ford Mustangs. The addition of a second full-time car signaled the team’s intent to grow beyond a single-family entry into a developmental program capable of supporting multiple drivers across a 33-race season.
The team’s expansion continued when Blaine Perkins was announced in December 2023 to drive the No. 29 full-time in 2024, and when a collaborative No. 38 was run with Viking Motorsports during that same season. Kyle Sieg continued with the No. 28 into 2025, while the team also returned to Chevrolet as its manufacturer. The technical alliance with the Haas Factory Team and the multi-car structure now define the modern RSS Racing operation.
RSS Racing Competitive Journey
From a one-truck family operation in 2009 to a multi-car Chevrolet team aligned with the Haas Factory Team, RSS Racing has steadily grown its presence across NASCAR’s national series. The team has logged more than 500 combined starts across the Camping World Truck Series, the NASCAR O’Reilly Auto Parts Series, the ARCA Menards Series, the ARCA Menards Series East and the ARCA Menards Series West. Although the team has yet to capture a drivers’ championship, it has built a reputation for fielding competitive entries on superspeedways and road courses, and for developing young drivers such as Ryan Sieg, Kyle Sieg and Parker Retzlaff.
Early Seasons and Development (2009–2016)
RSS Racing’s first chapter unfolded in the NASCAR Camping World Truck Series beginning in 2009, with Ryan Sieg driving the No. 39 at Milwaukee in the team’s debut event. The Truck Series program ran a limited schedule for several years, supplemented by part-time start-and-park efforts with the No. 93 and other truck numbers, including appearances by drivers such as Dennis Setzer, Mike Garvey, B.J. McLeod and Johnny Chapman. These low-budget entries were used strategically to fund the team’s primary Truck and Xfinity programs.
The team’s first Xfinity Series appearance came at the 2013 Indiana 250 at Indianapolis with Ryan Sieg in the No. 39, and the following year the team committed to a fuller Xfinity schedule. In 2014, Sieg finished ninth at Daytona and later posted a third-place finish at the same track, helping push Kasey Kahne to victory. He also finished sixteenth in Xfinity Series points that year. A second part-time team, the No. 93, was added in 2016 with Scott Lagasse Jr. at Daytona, and the team would continue to run start-and-park entries under that banner for several seasons.
Breakthrough in NASCAR O’Reilly Auto Parts Series (2017–2023)
RSS Racing’s most significant competitive breakthrough came in 2023, when Aric Almirola won the inaugural NASCAR Xfinity Series race at Sonoma Raceway driving the No. 28. The victory, shared between Almirola, Kyle Sieg, Alex Labbé and Brent Sherman across the season, gave RSS Racing its first win in any national NASCAR series and validated the team’s multi-car development model. The Sonoma win was particularly meaningful because it came on a road course, a discipline that has become an area of emphasis for the team.
The 2017–2022 stretch laid the foundation for that breakthrough. In 2017, Ryan Sieg posted a career-best second-place finish at Iowa Speedway, and the No. 39 made the Xfinity playoffs in 2016. The team also expanded the No. 38 to a full-time effort in 2018 with Jeff Green and J.J. Yeley sharing driving duties, and the No. 93 was renumbered to the No. 23 in 2021 before eventually running under the Our Motorsports banner. By 2020, Ryan Sieg was running the No. 39 full-time with CMR Construction & Roofing sponsorship, advancing to the round of eight in the Xfinity playoffs and finishing tenth in points.
In 2021, the team added the No. 28 part-time for Kyle Sieg, and a year later the operation ran a four-car Xfinity effort featuring the Nos. 28, 29, 38 and 39. The 2022 season included a sixth-place qualifying run for Parker Retzlaff at the United Rentals 200 and additional starts by drivers such as Joe Graf Jr., C.J. McLaughlin and Loris Hezemans. The diversified lineup helped the team accumulate valuable data across ovals, road courses and superspeedways heading into its first winning campaign in 2023.
Modern Program and Current Direction (2024–Present)
In 2024, RSS Racing ran a multi-car Chevrolet program headlined by the No. 39 of Ryan Sieg, the No. 28 of Kyle Sieg, the No. 29 of Blaine Perkins and a collaborative No. 38 fielded with Viking Motorsports. SciAps became the primary sponsor of the No. 39 starting at the 2023 Wawa 250, and the deal was extended into 2024. C.J. McLaughlin and Matt DiBenedetto shared the No. 38 during the 2024 season, with sponsorship and operational support from Viking Motorsports. The team finished 2024 with Ryan Sieg narrowly missing a win at Texas, where he lost to Sam Mayer by 0.002 seconds.
Heading into 2025, the team’s flagship No. 39 remained with Ryan Sieg, while Kyle Sieg continued in the No. 28. In November 2025, RSS Racing announced a switch back to Chevrolet as its manufacturer while retaining its technical alliance with the Haas Factory Team. The decision to return to Chevrolet came after several seasons running Roush-Yates Engines-powered Ford Mustangs and reflected the team’s effort to align its engineering and chassis supply with a manufacturer partner capable of supporting sustained growth.
Looking ahead, the team has signaled an intent to remain in the NASCAR O’Reilly Auto Parts Series with Chevrolet power and to continue developing young drivers through its multi-car structure. The partnership with the Haas Factory Team is expected to remain a cornerstone of the team’s technical strategy, while sponsors CMR Construction & Roofing and SciAps continue to anchor the organization’s commercial operations.
Philosophy and Competitive Strengths
RSS Racing has built its identity around family ownership, driver development and disciplined race execution. The team has historically excelled on superspeedways and road courses, with notable finishes at Daytona, Talladega and Sonoma, and has used collaborative entries with teams such as Reaume Brothers Racing and Viking Motorsports to expand its operational footprint. Its multi-car structure allows the team to share data across drivers such as Ryan Sieg, Kyle Sieg, Joe Graf Jr. and C.J. McLaughlin, accelerating the learning curve for younger drivers while providing veterans with competitive equipment.
Key Milestones and Major Moments
Among the defining moments in RSS Racing’s history are its 2009 Truck Series debut at Milwaukee, its first Xfinity Series start at the 2013 Indiana 250 at Indianapolis, Ryan Sieg’s third-place finishes at Daytona in 2014 and 2016, and the team’s first national series victory with Aric Almirola at Sonoma in 2023. The team also marked a significant organizational shift in 2025 by returning to Chevrolet while keeping its technical alliance with the Haas Factory Team, and narrowly missed a 2024 win at Texas when Ryan Sieg lost to Sam Mayer by 0.002 seconds.
RSS Racing Achievements and Results
Across the NASCAR O’Reilly Auto Parts Series, the Camping World Truck Series, the ARCA Menards Series, the ARCA Menards Series East and the ARCA Menards Series West, RSS Racing has accumulated 514 combined race starts, 1 race victory, 0 pole positions and 0 drivers’ championships. The team’s win came in 2023 at Sonoma in the NASCAR Xfinity Series with Aric Almirola, and the organization has consistently placed entries inside the top twenty in Xfinity points, with Ryan Sieg finishing sixteenth in 2014, eleventh in 2015, tenth in 2020 and twentieth in 2023.
NASCAR O’Reilly Auto Parts Series Achievements
RSS Racing’s O’Reilly Auto Parts Series program is the cornerstone of the organization and accounts for 393 of its 514 career starts. The team’s first victory in any national NASCAR series came in 2023, when Aric Almirola won the inaugural Xfinity Series race at Sonoma driving the No. 28. Ryan Sieg’s best individual season came in 2020, when he advanced to the round of eight in the Xfinity playoffs and finished tenth in points. The team has also posted notable results on superspeedways, including a third-place finish for Ryan Sieg at Daytona in 2014 and a second-place finish at Iowa in 2017.
Conference Achievements
RSS Racing operates as a single-entity team without a conference structure, so the organization does not record conference titles or conference-level results. The team has, however, finished in the top twenty in the NASCAR Xfinity Series standings in multiple seasons, including sixteenth in 2014, eleventh in 2015, fifteenth in 2017 and tenth in 2020. The 2020 round-of-eight playoff appearance remains one of the most significant conference-level benchmarks in the team’s history.
Divisional Achievements
Like its conference profile, RSS Racing does not compete within a divisional structure, and the team has not recorded divisional titles. Its competitive results are instead measured at the series level, with Ryan Sieg’s third-place finishes at Daytona in 2014 and 2016 and his second-place finish at Iowa in 2017 standing among the most notable individual results. The team’s first Xfinity Series win with Aric Almirola at Sonoma in 2023 also ranks as a landmark divisional-level achievement for the organization.
Series Achievements
Across the Camping World Truck Series, the ARCA Menards Series, the ARCA Menards Series East, the ARCA Menards Series West and the NASCAR O’Reilly Auto Parts Series, RSS Racing has made 514 starts, with 393 in the O’Reilly Auto Parts Series, 107 in the Truck Series, 11 in the ARCA Menards Series, 2 in the ARCA Menards Series East and 1 in the ARCA Menards Series West. The team has recorded 1 win, 0 pole positions and 0 drivers’ championships, with its lone victory coming in 2023 at Sonoma. Notable development drivers for the team include Ryan Sieg, Kyle Sieg, Joe Graf Jr., C.J. McLaughlin, Parker Retzlaff, Blaine Perkins, Myatt Snider and Alex Labbé.
