Click through each year to explore noteable EP3 Motorsports milestones


EP3 Motorsports was founded in 2015 by two BMW Factory Certified technicians that were looking to expand on their passions and focus more on the performance side of the automotive industry.

At the time of establishment, EP3 Motorsports was based out of an old 1,700 sq. ft. Napa building located in the northern Illinois suburbs.


With rapid growth and local community following, EP3 Motorsports moved into their new 8,000 sq. ft. facility strategically located in St. Charles, Illinois to be more centralized in order to serve surrounding Chicagoland automotive enthusiasts.

Platform Support

EP3 Motorsports remains competitive and passionate to the everchanging automotive space and expanded on additional vehicle platforms outside of BMW.

EP3 Motorosports officially began supporting Porsche, Lamborhini, and Ferrari in 2021 with a focus on custom fabrication and extreme engine builds.

Future Performance

The launch of the EP3 Performance Line of F80 and G80 products marks the beginning of the next chapter in the EP3 Motorsports journey. After years of installing products by nearly every manufacturer, the team had enough and developed their own products without compromise.

We are so grateful for our customers and the opportunity we have to share this passion with this amazing community. Please let us know how we can assist you in reaching your automotive goals.
