Wisconsin Racing: Formula SAE Lincoln

DEI Sponsored University of Wisconsin-Madison takes 3rd places at Formula SAE eventOn June 20th Wisconsin Racing joined approximately 85 other Formula SAE teams from 7 different countries in beautiful Lincoln, Nebraska. This is the first time that the FSAE West competition was held at Lincoln Airpark, in years past it was hosted by the Auto Club Speedway in Fontana, California. The move to Lincoln made perfect sense: not only was our drive shortened by 25 hours, but in 2009 the Sports Car Club of America relocated its Solo Nationals event to this same location. Lincoln Airpark is also home to monthly autocross events for the local SCCA members.  Over the next four hot and windy days, Wisconsin Racing and the WRS212 once again took on the competition, and had a great time as well.

Wednesday 
After a mostly uneventful drive through the scenic rolling hills of Wisconsin and the seemingly endless cornfields of Iowa, the team rolled into Lincoln Airpark. Wisconsin Racing wa prepared to once again represent the state of Wisconsin, the University of Wisconsin - Madison, all of our family and friends, and most of all our sponsors who helped bring the WRS212 to life.  After a strong 10th place finish at the Michigan International Speedway in May, Wisconsin Racing hoped to further showcase the strengths of the WRS212, and compete for a win.
