RR3 Wiki:Most Profitable Races

It sucks, but there are a lot of other options. Classic Ferrari Showdown has always been a good option.

For single races, if you upgrade the PORSCHE 918 RSR CONCEPT (150 to buy and 151  to fully upgrade) fully, then you could practice Porsche 918 RSR Concept (Exclusive Series) Tier 17.1 Endurance Race and get it to be a perpetual endurance race, you could have a race for fame bonus days that would rival the 10-lapper.

There are plenty of posts and videos on Perpetual Endurance at Porsche Test Track Short that can show you the way.
