It depends which upgrades you select.

I think you definitely need Engine stage 4 for top-speed at Daytona.

You can always hold-off on the final Gold-only upgrades for Exhaust and Tyres and see how you get on, if you're struggling you can add them last-minute as they're instant upgrades.

Good luck.
