This thing is basically a off road civic. The list of aftermarket parts are endless. Makes me glad i picked the black diamond with a soft top. Everything it lacked i upgraded. Only recall has been a software update. Plan to keep it well after warranty.
If you have the oem rock guards. Couldn't you install these on the rear of the rock guard? Just a lazy thought. But for the op argument when your rear tire hits the mud or muddy pot holes with momentum it will push the mud or muddy water forward. Doesn't have anything to do with tire tread.
