    Wheels rubbing car body. I've seen plenty of efforts and techniques to reduce friction for when the hub rubs the body. But I thought the point was to get the wheels not to touch the body, so why the effort to reduce friction at the body? If truly worth the effort, what methods are proven good? Thanks in advance.

    So, again, no expert here. But, when I see a pro give tips and tricks on this forum, I cut and paste them into a running document that I have. So, here's what I have in my notes in re this question:

    "Sally Hansen Teflon Tuff fingernail polish (or some other maps strength or diamond tough), put 6 to 8 coats around the axle holes (about 1/2"). Let each coat dry before applying the next. After you get all of your coats on and it has dried overnight, use a tread conditioning tool (fingernail buffing bar) to smooth and polish the areas.)When it's nice and shiny, add a couple coats of your bore wax and buff off the haze when it dries."

    Now, does it help? Here's how a pro explained it when I asked that question about something else. "All these small things add up to a thousandth here and a thousandth there. You add them all up..." You get the idea.

    I think I read the exact same clip last year. Got Sally Hansen Diamond Tough hardener. It just seems like a lot of useless work since the wheels are not supposed to rub body anyway.

    When positioned properly, the DFW is the only wheel that rubs against the body.

    The other spinning wheels are done in case you get a wiggle, and you will get a wiggle eventually. You would rather wiggle fast than wiggle and hit the brakes at the same time.

    Sometimes, on tougher races, you’ll have cars wiggle on every pass ,I’ve had plenty wigglers myself.
