Hi all in free play mode what is the minimum number of laps to maximise the payout (when does the payout stop increasing). Also does class effect the payout in free play mode. Thirdly what is the highest paying event in the game (career mode). Thanks 
I don’t think there is a Max limit or capped figure.
From what I know it pays based on the distance driven.
I do a lot of laps on the rivals mode in the R class on the old Le Mans track. Do ten laps or so you get mega XP
The events at Le Mans Full have the highest Gold medal payout (9300 credits):
Modern Grand Touring
Early Grand Touring
Ultimate Track Toys
Prototype 1 Racing
Modern Grand Prix
1970s Grand Prix
but I suspect credits per minute played matter more to the player, and I don’t know which events are best in that calculation.
Idk about the minimum number of laps to maximise the payout in free play, its rather the more laps the higher the payout,
the fastest and easiest way of maximizing payout in free play is doing as many laps as possible,
preferably on shorter or easier tracks, which can be done fast
some recommend doing indy oval, because that is the fastest and easiest way of doing many laps with a high payout because of xp and level up credits
you maximize the payout because of the level ups, the more laps the more level ups (35k or 70k per level up depending on whether you have VIP or not)
The biggest payout right now is the last Silverstone race in the B rivals. You have to race the leader who posted a -5 second time. See the thread on -5 second Silverstone, the payout is huge. Not sure how this happened, but it is interesting.
Try X-class at Indianapolis oval in free play and run as many laps as you can tolerate without getting too bored with going left all the time. Hop into an IndyCar, if you have one, but anything you’ve got that is just about maximum top speed on a superspeedway will do the trick. Make sure to turn off assists and ratchet the Drivatar difficulty up to unbeatable. It doesn’t even matter if you aren’t all that good because it’s just an oval. You can cover 2.5 miles and a full lap every forty seconds, give or take, depending on what car and setup you have and exactly how good you are. As long as you have a good car and setup, the AI shouldn’t be a problem even on unbeatable.
