Reached over 250mph in a Standing Mile Event
This can easily be done in the Nissan Skyline GT-R (R32) Speedhunters. Once you get the hang of it, your max speed will be around 250 mph every time.
If you like me live in a country the uses the metric system its 402 km/h.
8 Second Club
Ran a Quarter Mile in less than 9 seconds
If you use the Nissan Skyline GT-R (R32) Speedhunters and hit the gearchanges perfectly, you can get times below 8.5 seconds so getting below 9 is no problem.
Ready to Rock
Won an Online event in a Speedhunters Edition Car
This trophy can be quite tricky because you need to find someone else with the Speedhunters DLC. If you create a lobby with the Speedhunters DLC enabled you might be lucky to get someone in it, but its quite rare.
Another option is of course to boost it. This can be done in any game mode and even in a private match, just make sure you enable the Speedhunters DLC and pick a car from the DLC.
