You want to complete Wreckfest with 100% and unlock the Platinum Trophy? Then you also have to master the following task – Reach 210 Km/h (130 Mph) With Rocket
Go to your garage by the button My Cars and grab the A298 Rocket.
But before you can unlock this high-speed trophy, you need to upgrade your vehicle. Go back to the menu and select the upgrades.
If you are in the tuning menu, use your best upgrades and remove any armor from the vehicle.
Did you do everything, start a Custom Event, there you decide on the Motor City Circuit Track. Now go to the Event Options and set that you do not want opponents (opponents 0).
As you can see in the video, you can also do some finetuning! Good luck with this task!
