6 second car
I have gotten both the Toyota Supra and the Zonda down in under 7 seconds.
All with level 3 parts. First of all you will need to adjust a few settings.
Start off with the engine, follow my other hint to push your car up 100hp.
Then make the rear wheels with as much tread as possible with a large profile and hard suspension. Then drop the pressure below half way,(actually done with real race cars) now make the front tyres considerably smaller with a softer suspension so you can absorb the launch start, then change the direction of the front tyres to point inwards so it is harder to turn but better for the drag strip. Now gears are tricky, you want the gears sorted in an asending order with the 6th gear being the highest. You also what the drag spoiler fully extended. Adjust the NOS setting to be more explosive than lasting
As for the actual drag race you want to hit perfect launches all the way down, easier said than done but to beat 7 seconds you need to.
Around 2nd and 3rd gear hit NOS and that should take you through to 5th gear. The hard part is keeping your car in a straight line when you come down from the launch, which I have no real advice for.
Then pick your favourite track and your favourite side, as it does make a difference, and max out the burn out and then try and try.
