The Cooper Union Motorsports, is a team of 20 people devoted into building a race car for the Formula SAE (FSAE) competition. This project is divided in multiple subsystems. Smaller groups work towards the completion of each subsystem to achieve the overall goal of the project. Currently Stepan is the Lead Vehicle Dynamicist of the car. He is in charge of the design and manufacturing of the suspension, steering and brakes subsystem of the car.

In the past Stepan has had other roles in the team. During the 2016-2017 season he was the Lead of the steering subsystem. The year before he worked on the safety features of the car, and assisted in creating the final CAD of the whole car. Finally, during the 2015 Fall semester he worked with a group of other students and prototyped a pneumatic piston activated semi automatic clutch.

​

Apart from Stepan, there are other members in the suspension, steering and brakes subsystems that contribute into the designs and manufacturing of the components. The following visuals illustrate the work done in those subsystems. All the designs are first CADed in SolidWorks and many of the parts used are machined by the team's members in Cooper Union's machine shop.
