Hello vlad_raiter,
welcome at Stridaforum!
Oh well, the fenders…
An annyoing detail, unsolved by Ming since…hmmm… 
The most easy solution is to remove them,
yes sorry - that doesn’t help you.
Please try the forum search and use also the word “mudguard”.
Disc brakes:
I think neither expected nor usual,
you might try to adjust the brake pads.
You will, most likely, already have the newer caliper versions on your EVO,
adjustment advice can be found either on the CD manual - look for “861-862 disc brake.pdf”
or here (??):

Presumably you’ve discovered the alternative (upper) hole for the seat pin;
to understand the function of this pin I’d recommend to read Ming’s
QR seat manual-0418revised.pdf page EN-3,
here’s a possibility to milden the limitations of the pin system.
Insider hint:
We’ve meanwhile mounted several seat moldings - out of that experience:
We do always recut both threads of the seat pin holes in the frame with an M5 machine screw tap.
(Primarily to remove the paint inside of the thread!)
That’s indeed delicate work; you’ve got one chance per hole to hit the original thread while carefully watching the angles
