Virtua Racing has two types of cabinets, one is Deluxe and the other is Twin.
When enabling the Grand Prix mode in this deluxe cabinet, I think we need to find out what the actual settings should be.

I'd agree that we'd like to see some actual hardware results first. To me a "Grand Prix" mode is kind of dull without another players to potentially race against which would stand to reason needing more than one cabinet.

Maybe an BTANB? I don't know anyone with an Virtua Racing PCB so I cannot confirm if it is an BTANB

Virtua racing in single player (link) has 4 laps, sets in single player (no linked) has 5 laps and not grand prix

Possible BTANB, chance is big, only works if link "1 player link mode" (x.x.x.x :10001 <-> x.x.x.x:10001 in network mode

Lets Acknowledge for now until a more definitive conclusion can be reached and agreed upon.
