TM Master Cup Series Crown Jewels

The TM Master Cup Series Crown Jewels is a moniker given to the four greatest achievements a driver can earn in the TM Master Cup Series. Earning all four is what is known as the "Grand Slam".

The four "Crown Jewels" consist of three races: the Karjala Grand Prix, the Round of Indianapolis, and the Round of Decatur. The fourth jewel is, of course, the driver's championship.

Only three drivers have completed the Career Grand Slam: Leonid Roderick, Alexis Rainsford, and Benny Dwyer. Roderick is unique in that he's the only driver to have done it twice.
