In a high-level competitive racing series like the NTT INDYCAR SERIES, finding the slightest edges can make the difference between a P1 and a P10 finish. It takes diligence and precision for Arrow McLaren to capitalize on opportune moments, even in the offseason when the racing has stopped. 

At Arrow McLaren headquarters, the team utilizes a variety of tools and machines that all play a part in building faster race cars. One of those machines is the GENMILL 4024 CNC Machining Center, which cuts, shapes and creates precision parts and prototypes designed by our engineers.  

“Expand plays such a big role in what we do here at Arrow McLaren,” said Mike Otte, Manager, Bodywork at Arrow McLaren. “Their machinery allows us to be innovative in the shop so that we can be fast on the track.” 

Arrow McLaren and Expand supplies the latest in CNC machining technology that fits our specific needs. CNC machining is key for Arrow McLaren because it significantly reduces the amount of time needed to create the specific parts needed to make our papaya race cars outpace the field. 

Jacob Hartwell, Machinist at Arrow McLaren, explains how valuable the Expand partnership is to the team and how Expand helps maximize performance in the Arrow McLaren Chevrolets. 

“Expand works alongside us to ensure we are fully utilizing the capabilities of their precision machining equipment,” Jacob said. “The team provides the latest tooling and expert advice that enables us to maintain accuracy and efficiency in our shop. Their unparalleled support allows Arrow McLaren to compete at the highest level.” 

The CNC Machine produces critical parts all over the car – from gearbox plate covers to suspension components, even specific measuring tools that are designed just for pieces of the car that are proprietary to Arrow McLaren. Much of this process falls on Jacob, who’s responsible for making sure the software is programmed correctly and the machine is operating properly. 

The result? Finely-tuned and perfectly-fitting parts, like these front and rear rockers for the suspension, that help give Arrow McLaren that ever-important edge. And this is just one of the many examples of how Expand provides the precision and performance Arrow McLaren needs to land on the podium.
