Frankly, with two gas tanks, I always prefer the flares centered on the filler caps. And then move the axle back to recenter, if needed.
But that’s why we make bigger flares nowadays, wit more of an angle on the front so they can be moved rearward a little bit, and still have more clearance at that leading edge.
Definitely doesn’t look good with the flares, not centered under the caps, OR the tires not centered under the flares.
Talk about a two edged sword!
What flares are those? Fiberglass?
