The GT5 expansion includes 6 new cards that only have 5 black gear dice. However, they more than make up for it with the addition of a new boost die! This green die works just like a brake die except that it allows you to skip a gear when accelerating instead of slowing down! New dashboards for the GT6 cars in order to race them against the GT5 cars. These new boards modify the cars slightly, balancing them out so that they can race together on equal terms, yet still retaining their unique traits.
