Unfortunately the Apex Wednesday cups are the only way to get free upgrades, however this events rotate constantly, which means like every one month you can only get free upgrades. Unfortunately this week's Apex Wednesday is Boosters, so you have to farm credits or Mastery to get the last Top Speed upgrade. I got the level 5 free Top Speed upgrade from there.

Even if the event exists, I believe that you need to finish in a certain leaderboard position to get the free B Class upgrade. Most race rewards only award C or D class free upgrades.
