When braking from a high speed, the car’s front end starts bouncing, and the only way to fix it is to raise the front ride height to unrealistically high levels as well as making the front suspension too stiff, which forces the player to concede a good bit on the car’s potential pace.
There are several other cars with this issue, such as the Nissan Silvia S15 and the Mazda RX-7 Spirit R being the most notable in my mind.
