So far, I have all of the "extreme" ranks for all missions except for one which is quite impossible to get the "extreme" rank.

You know the mission where Storm has to beat the robot in 1:10 or less, my personal best is 18.10 secs and I can't seem to get that "extreme" rank for this mission. It's like I have to give it my all to be really, really, REALLY fast to beat that robot. Need some help on how to get "extreme" and what do I have to do to beat the dam thing?

Only that mission left and I would have had Super Sonic by now if it wern't for this impossible mission.

As soon as the race starts, Gravity Dive all the way to the garage door and wait for it there.
