The GT5 expansion includes 6 new colored plastic car models, 32 dashboards, 6 driver cards, a new die and a rulebook.

Includes: Brand new set of dashboards for both asphalt and rain tires. 6 new cars that only have 5 black Gear dice. However, they more than make up for this with the addition of a new Boost die! This green die works just like a brake die, except you can skip a gear when accelerating instead of decelerating!

New dashboards for the GT6 cars to race against GT5 cars. These new boards slightly modify the cars, balancing them out so they can race on equal terms with each other, but still retain their unique characteristics.
