Character and vehicle combo guide

The best characters currently known for Speedruns are Sandy and Lucy depending on the track. They cost 160 and 150 tokens respectively.

- Sandy has slightly better turbo and acceleration and is generally faster on tracks with fewer tight turns. 
- Lucy has slightly better handling which is better for tracks such as Retroland where there's tight turns and lots of drift chaining. 

the best vehicle combo seems to be:
- Johnny 13 bike (105 tokens)
- Water Tribe spinners (30 tokens)
- Ecto Turbo exhaust (unlock by winning 2 slime scrambles)

Bikes have better stats than karts and this combo provides very high speed which is the best stat in the game, for RTA runs it may be better to use a bike with better handling/accel such as the kamp koral bike (unlockable by winning 40 slime scrambles)

The best Chief for RTA runs is Mrs Puff (unlockable by beating challenge#22)
The best Crew engineers are:
- bobo (unlock by beating challenge#27) 
- prof.membrane (unlock by winning 8 online races)

You could definitely switch out membrane but for the insane slime scramble especially he is very useful to dodge attacks.
