Ditto for Dodge on the ACR: it's possible they will void your entire vehicle warranty if you change the aero device and suspension settings from stock. You don't even have to physically be on a track.

The dealer provides a disclaimer that the buyer signs when taking delivery, acknowledging they're aware of the impact on the warranty should they decide to make these changes.

Isn't it shady of Dodge to be promoting this car as being capable of beating the next fastest car by 5 seconds in test after test, but if you adjust the suspension (even to fix a defective factory setting, which has happened), they reserve the right to deny your warranty claim?
The ACR can reach those performance levels with the stock setup. It is IMPOSSIBLE to match the numbers for the GT-R without launch control.
