After listening carefully to feedback on the sponsor income changes around Quick Races, we have restored them to the previous levels. The changes will only come in to effect on new contracts signed from the time of this post.
I took time to discuss this with some of our more experienced players to gather more opinions before taking any action. The experiences shared with me made it sound like it the reduced sponsor income made it necessary to watch ads or use Tokens to maintain a low level team's cash balance. That was not our intention, so we've tipped the balance back to what it was before the release of Quick Races.
Many changes will be coming to the game in the weeks/months ahead and restoring this also fits nicely in to the bigger picture of where things are headed.
