Family. Dirt. Mustang.
An Ontario race team built around Pete and the Mamo Family — and one rowdy, race-ready Mustang.
Built In The Garage
Cosco Mamo Motorsports is a family-run dirt oval team based in Ontario, Canada. What started as weekend wrenching in the garage has grown into a full weekly program at Merrittville Speedway.
The 3J Mustang was designed and built from the ground up by Noah Mamo, owner of MRM Fabrication, who also sponsors the car. Owner and crew chief Pete Cosco works on the car and keeps it sharp between race nights. Driver Jacob Mamo wrenches on it through the week and wheels it every Saturday, chasing feature wins under the lights.
Dave Mamo is always around the shop lending a hand, and Laurie Mamo — Jacob's mother and owner of Ridge Custom Crafts — backs the program as a sponsor.
Racing is a family sport. Every result — good night or bad — comes back to the people in the pits, the shop, and the stands.
No matter how the night ends — a feature win or a broken car on the trailer — everyone on this team is smiling. That's the part that keeps us coming back.
