What is the fastes way to get 50 percent??

[Dodge Viper]

I want to get all golds in the Amatuer leage so I can get the
Dodge Viper Team Oreca. But I can't play out the last three races of the GT World Championship. So when I get 50 percent I get the Corvette C5R, and I can use him for those races. But my question is how to get 50 percent on the fastest way.

Please help my!! Thanks!!

Play. Race. Buy.


A LOT!

Or would it make more sense to make it a recipe...

Play. Race. Buy. Repeat.

I go for sim first, so you can use your sim garage in arcade mode.
