Well, here goes my best time for now, I still have room to shave off at least 1.5 seconds, so I think I can do better at some other time of the day (It's 4 A.M at the time that I posted this xD).
Oh, I'm doing this with the DS3 too.
EDIT - Screw sleeping, i'm not stopping now, this is my first edit from my 1'40.010 time, it's now at 1'39.329 and I still did some mistakes. I estime I can reach lower 1'38.
EDIT 2 - Entering the 1'38s, not sufficient to put me on the podium here yet, but i'm getting to it, did a massive drift on curve 4, so I guess those are my last .6 or .7 seconds to shave in this track, after that I don't see where I can improve more xD
EDIT 3 - I think that with this time, I entered the Bronze place in here :P I have to go to sleep, since I can't see anything straight right now >_< I think that I can still shave some .3 or .4 from my time, but both Oniichan and Jaaau! times are insane >_< Did they do it with a Wheel?
