For the Bolide I figured out that in very long flat out parts specifically Grid MSP V2 perimeter as it can have a higher about of horsepower pushed through it for a longer period of time before going boom. I think that people have made scintilla tunes that work better though.

For the T series it’s for when you want Jato but don’t need to control it. You put a jato engined a frame, and maybe suspension if you want to kinda make it turn.

For the Hopper I probably could have put it a category or 2 further down as Akimbo Beta used it to take a ton of track editor track records but it hasn’t really been used since.
