Notes:
Gus Schrader was an eight time National Sprint Car champion for the International Motor Contest Association (IMCA). From 1933 to 1941, the year of his death, he missed the title only in 1938, when the champion was Emory Collins. After a brilliant career which included also a start at Indy 500 in 1932, when he crashed after only three laps, he announced his retirement as he had purchased a farm in Iowa and meant to spend the rest of his life there.

Schrader's final race was scheduled for Wednesday, 22 October 1941 at Louisiana State Fair Speedway in Shreveport. It was the last event promoted by IMCA before racing activity was suspended because of the World War II.

Gus Schrader won the first heat, driving his Offenhauser-powered self-built car. The second was won by his good friend Jimmy Wilburn, who was driving a car that Gus had helped him to purchase. During the feature race Gus Schrader's car hit Wilburn's, and Schrader, not using a safety belt, was thrown out of his car. Schrader lost his helmet in the accident and suffered severe head injuries. He was transported at the Tri State Hospital in Shreveport, Louisiana, which is located just about one mile from the track. Schrader died there shortly after admission.

The vehicle entered by Schrader in his final race was the famous Schrader #5, a Curly Wetteroth chassis to which he had made several changes, equipped with an Offenhauser engine. The car was only slightly damaged in the crash and was then sold and repaired to race again. In the following nine years two more drivers of the car were to lose their lives: Eddie Nicholson at the Milwaukee Mile in 1946; and Bill Anderson at the Mitchell Speedrome in Indiana in 1950.

It is believed that there was problem with the steering arm after Gus Schrader had converted the car to a cross-spring front. According to Charles Davis, who later owned the car, the spring shackle was mounted on the front axle, too close to the steering arm. In certain circumstances the arm could become entangled with the shackle and take the steering away. After Anderson's accident, Peaches Campbell, who owned the car at the time, changed the steering geometry. The car was raced for many more years without serious incident.

Gus Schrader was elected posthumously to the National Sprint Car Hall of Fame, and the Iowa Sports Hall of Fame. He is buried at Inglewood Memorial Park, Inglewood, California.
