So, I got a nice ZR1 Corvette and RM'd it, and then finished it up by purchasing any remaining upgrades in the tuning shop.
Then, I dominated the American Championship in Extreme. I still have all the other events to do in Extreme yet, but I'm so excited that I can do this one now. Grinding has finally become easy. No more BS 30,000 rewards for races. This is the big time.
If my math skills are correct...
It takes me 4 minutes flat to do 5 laps on Indy Speedway with the fully modified ZR1.
The award is 98,000 credits.
Let's say, by the time I exit that race, and re-load it again and get back to racing it's 2 minutes max.
That means... every 6 minutes I earn 98,000.
That's 980,000 per hour. HELL YEAH.
Again people, that's the American Championship - Indy Speedway race in Extreme. $$$$$
Edit: To the poster above, it's a level 23 event.
Edit 2: And I remember someone already mentioned this awesome event a few days ago, but I'm so happy right now that I finally am rolling in the cash lol.
