see my post from about 1 day ago, with my experiences with all level 1 upgrades, all level 2 upgrades, and also level 3 upgrades.

In short to comfortably finish it level 3, although not all of them are necessary, as I was able to complete it with a certain margin.

see also the post from RR3 Michael P, right below mine.

But at the end I just decided to skip by paying only 45gold, as I will use the RSR2013 to get 100% (eventually, when owning all cars) for the series masters of speed by upgrading only that one to 85PR (cheaper compared to Aston martin (including no 45 gold to skip 9.3) and RSR2014)
