Looking at the upgrade diagram times and the Born to Win event, it appears that several upgrades are designed to fit around the two days you are using the F1 GTR. This way your upgrades will be complete before you use the P1 GTR again.

However, if you do not upgrade before the break and get in a situation where you need them before the end, [b]you will have to pay to speed them up. [/b]

Fair warning.
