MRK Motorsports was started in 2007, and quickly established its reputation as Aurora & Streetsboro, Ohio’s local race car manufacturer. Michael Kilroy started the shop in his garage , with no loan, no partners. Slowly, with hard work, long days, longer nights, and with great sacrifice, Mike built his own company, and continues to build his cars the same way, from the ground up. MRK Motorsports builds cars ranging from all prices.
