A04 Canyon: 16.092 - Rumelius99 --> He goes through a wall after turning around and steering on the right
A04 Canyon: 18.527 - Captain Harlock --> Same reasons as Rumelius99's time
A04 Lagoon: 18.737 - Sexy++ --> Some speed hacks from the beginning
Thanks in advance!
Edit: The A04 Canyon times were actually exploited from missing blocks in some versions if I got it correctly. The times still need to be erased but they're not cheaters themselves.

All the times here are from an old version with a stronger magnet's boost which is impossible with the current version's physic. I know at least Sexy++ is one of the developper (so maybe Sypher is one as well), but it's not fair at all and make the SPs wrong.
