Day on Le Mans. I haven't completed yesterday's speed record yet, so trying this stage with 14 upgrades
Goal 1 - autocross. Beat the 38 second target without issues
Goal 2 - choice of 3 1 lap cups. Just different time of day. Was 10 seconds off required target. Skipping for now
Goal 3 - elimination. Even crashing into the barrier, only got 341KPH. So going to need to upgrade to 16 or even 18 to pass both yesterday's speed record and this goal
Goal 4 - 1 lap cup. Starting in 8 and Ahmed behind. As long as you can keep a bot in between, easy goal

Reward 20,000/15

edit - 16 upgrades, top speed of 343.  18 upgrades, top speed of 351.  Yuck, 20 upgrades to get the 355.
