According to this video clip, GT7 will offer the biggest number of tuning parts ever seen in a Gran Turismo game, so we can’t wait to find out more about this nearer to launch.
The video also briefly gives a glimpse of the new wheel selection menu screen. Rather than a single, long line of wheels, there’s far more on-screen at any one time, and it looks like players can buy wheels directly from a specific store rather than waiting for them to appear in the Mileage Exchange. That could indicate that the Mileage Exchange itself won’t appear in GT7.
