For Road to Le Mans: If you'll get the car in the end, you might even upgrade it to PR94 - it will cost you 90 gold, but the event itself rewards you with 255 gold, so it's net positive. For R$, as A Wikia contributor said, 1 million is enough. It's time consuming though (in-game race time I mean), so consider that. But I disagree with the above contributor about Zenith - You can get through zenith by buying 80 GC worth of upgrades for the Venom, so it's not much.
