- Prototype Racing Tire, circa 1960 - Bobby Unser made his reputation in the Pikes Peak International Hill Climb. The course had a dirt surface when Unser raced it, so he searched for ways to improve tire traction. Unser tried grinding up various substances and mixing the results into rubber to produce a tire with more grip. The most effective material turned out to be ground walnut shells.

- Jerry Unser Motor Company Lab Coat Worn by Bobby Unser, circa 1960 - Jerry Unser established his auto repair garage in Albuquerque, New Mexico, in 1936. All four of his sons -- Jerry Jr., Louie, Bobby, and Al -- worked in the business at some point. Bobby Unser used this shop coat while running the garage around 1960, before his racing success allowed him to make driving a full-time career.

- Scale Model of Indy Car Side Pod Tunnel Used for Airflow Testing, 1981 - Bobby Unser tested scale model body parts, like this one, to design a better race car. He used a flow bench -- typically used to analyze engine parts -- to determine which design would most effectively push a car closer to the racing surface. This downward force provides greater traction for higher cornering speed. Unser's innovative approach allowed for more development while reducing the amount of full-scale wind tunnel and track testing.

- Champion N9YC Racing Spark Plug, 1960-1980 - Spark plugs ignite the air-fuel mixture in an internal combustion engine's cylinders. High voltage jumps across a gap between two electrodes on the plug's bottom and creates a spark. Racing spark plugs are optimized for maximum performance and durability in race conditions, where engines run at high speeds and high temperatures.

- Orifice Plate for Cylinder Head Exhaust Airflow Testing, 1978-1982 - Bobby Unser used this clear plastic part on his flow bench to help test race car engine parts. A flow bench is typically used to test the airflow through engine parts such as carburetors, cylinder heads and air filters. Testing led to better designs and engine performance -- and better race results.
