Sneaking in without a roll cage

They won’t know how fast your car is, and neither do you, until you run it. So, you’ll be able to run until you pass 11.50

EXCEPT for the kill switch thing.

It’ll take some passes/seat time before you get your car set up and are hitting shifts consistently to use all your new found power.

I haven’t seen your build, what’s the rest of your car combo? Mainly weight, converter, gears, tire diameter, and suspension upgrades. As previously noted, 600 hp isn’t a free pass to fast. Not trying to be insulting, just needing to know if everything behind and around the power is set up to use it is all.
