I was wondering if say 15mm front 20mm rear would produce enough drag that it could affect range in any significant way? Standing directly over the top of the fender it's flush but down low next to the body side you can see more of the tires sticking out. Just wondering if for longer trips it's best to take them off or is 15/20 is just nowhere big enough of a spacer to cause any noticeable range loss.
Thanks!
Thanks!
