Hi i am TBS123SPARKY from roblox.
Adding NOS would be a great stuff for car lovers
Player should be able to buy NOS from the Perfomance section in Customizing option
Buying NOS with scraps or credits would be good for non robux players, NOS can be a little less powerful than the rocket boost so that it would be fair.
And another extraordinary feature: Using NOS more than 7 or 8 times should make the engine explode ( this makes the NOS feature more realistic)
i hope my suggestion gets noticed by everyone
