nclp: 2-6 with the Rocket fully upgraded, done completely by just pressing WD, all the race... if not fully upg, tap W while on top/bottom of the track, aim for the checkpoint
For 2-6 I've used Speed Supreme. It's dirt so to have speed you want something that doesn't drift so much.
For 2-10, Pocket Rocket. And don't do the whole course without lifting your finger from the W key.. take your time, you have plenty..
Little car guide:
-Ninja Burger: I've used it until I got Speed Supreme. Stock.
-Drift Royale: didn't even use it.
-Speed Supreme has the best grip in mid-open turns. Hard to keep it drifting, but doable (It's the car I've used the most, until getting Super Drift Burger)
-Pocket Rocket is Special for handling, it's the one who can turn the gnarliest curves, and ZigZagging to keep drifting. Special for the "1 lap drift"
-Super Drift Burger has the best speed while turning in a closed curve. (you'll notice it's the only car you can actually turn in 180 while still going forward)
I loved it. I currently have all upgrades on 3rd and 4th car, the truck and the airplane. Once you understand the physics of the game (which are actually VERY GOOD.. without counting the CPU Cars doing impossible things)
I give it a 4/5 because there is no 4.5/5
