How to drive
You will need to launch from idle, so don't hold brake or accelerator. Launch in 1st gear and shift at redline.
This car is the fastest 1/4 mile car I've tested so far. Very competitive car overal and will do you very well in online lobbies. This tune will keep up and have a good race with most well tuned GT-R's out there.
Update:
Decided to fine tune the gearbox because this seems to be the most popular 1/4 mile car right now.
