Former NASCAR O’Reilly Auto Parts Series team AM Racing (AMR) is suing Sigma Performance Services (SPS), claiming that the ARCA Menards Series team is illegally in possession of assets that belong to the organization and include intellectual property of the team.
The two parties have been entangled in a purchase agreement gone awry since last October, according to court documents, when SPS tried to acquire the assets of AM Racing, which fielded an entry in the NASCAR O’Reilly Auto Parts Series (formerly known as the NASCAR Xfinity Series).
However, in January, those plans were called off by AM Racing, and the two operations appeared to go their separate ways – with AM Racing fielding entries for Nick Sanchez and Daniel Dye in the NASCAR O’Reilly Auto Parts Series and Sigma Performance Services fielding an ARCA Menards Series entry for Daniel Dye and others.
Now, AM Racing claims Sigma Performance Services is holding onto various assets that belong to, and are not easily replaceable by, the organization – including one superspeedway chassis, two intermediate chassis, an ARCA engine, and an ARCA Garage Box, all together valued at $320,000 – as well as “impermissibly utilizing, intellectual property that [SPS] gained access to during the Due Diligence period,” valued at $350,000.
AMR, with Kevin Cywinski as its acting Manager, believes that it is entitled to all of the above-listed assets, saying that the organization either purchased and modified, or built the chassis that Sigma Performance Services is currently holding on to, as well as purchased the engine, plus the garage box and its contents.
The Plaintiff, AM Racing, is looking for injunctive relief from a judge to get its property (both physical and intellectual) back, and although their original agreement does say an arbitrator must be used to settle all disputes, the team believes the matter is urgent enough to seek relief from a judge.
“The provisional remedy is needed as the matter is urgent,” the court document reads. “The property is utilized in stock car racing, and collisions are common in the stock car racing business. A collision could damage or destroy the property. The Plaintiff stands to suffer serious irreparable harm if the injunctions are not issued in that the special and unique character of the property means that if it is sold, damaged, or destroyed, it cannot be replaced by the Plaintiff.”
AM Racing is requesting that Sigma Performance Services return the property and do so without utilizing or selling the physical or intellectual property or altering it in any way.
AM Racing fielded the No. 25 and No. 52 Ford Mustang Dark Horse in the opening seven NASCAR O’Reilly Auto Parts Series events of 2026, before shutting its doors. The team’s drivers included Nick Sanchez (No. 25) and Daniel Dye (No. 52). The organization also fielded ARCA Menards Series entries as recently as 2025.
Sigma Performance Services fields the No. 23 and No. 24 in the ARCA Menards Series and ARCA Menards Series East, for several drivers, including Daniel Dye, Connor Hall, and Caden Kvapil, amongst others. The team has entered six races in 2026, collecting three top-fives and five top-10s.
