@e5c4p3artist, the 10k of gems were not mentioned by me, but by @mighty-red-1.

I will explain you how I did it:

Opening 10 Luxury toolboxes costs 360 gems. It gives you approximately 200 blueprints. To buy all premium carts, you need 5000 blueprints, so approximately 25 times 360 gems. This is 9k of gems.
You also need to upgrade the Phoenix Star for 1000 blueprints, ~2k gems.

I got all my gems from the game, when they “upgraded” it to version 2.0.

@vanny90 You have the 300cc Phoenix Star?

Maybe one hint. There are two “ledges” in the course. Halfway the second “ledge”, you can take a shortcut and jump onto the main track. This saves a little time.

@mighty Red: you were right.
Got it done with the Phoenix Star at 300 and three others at ~285. Didn’t buy any new seedway kart, because in levels 10 and 11 there are no seedway courses.

Only “problem”: the 287cc Trash Thrasher is just too fast. It’s more like an airplane than a kart and crashes all the time. This makes it (currently) impossible for me to get a 3-star score on most stunt levels.

@Mighty Red, thanks. How many karts do you need at 300CC to finish the campaign? I have 2000 blueprints left (which is 2 upgrades from 28x to 300cc), so I want to spend them wisely.

I can’t get level 10.2 done. Have the Phoenix star at 284cc. Any hints?

I just upgraded my Cherry Juice to rank 5. In the store, I can now buy:
Cherry Juice rank 6 for 3250 snoutlings (heals 550) and
Fruit Cake rank 5 for 4250 snoutlings (heals 300)

What are currently the maximum ranks for each?
