Racing and shooting have a lot in common - but the aspect I was thinking about is both involve machines that need to be kept in good working order.
Scott Wagner just did a great blog about one firearms oil that had its roots in racing.

Now I’m not saying it’s better than Hoppes 9 or any other suggestion in What's better than Hoppe's 9? But it might be worth taking a look at.
Both require attention to detail.

I have been using automotive products in my guns for DECADES. I used Slick 50 grease to lap my 1911 slides. At one point the “utlra accuracy boy” were using a mix of Lucas oil and Shooters Choice as a bore cleaner. To this day I will take a parkerized bolt for an AR platform and soak it in a jug of 10W-30 before I take it to the range. I use ARP Assembly Lube when screwing in a new tube on a rifle. Between auto racing and aviation performance products I have a crap ton of lotions and potions for my guns and cars.

Both require attention to safety.
Both will make you broke. On the bright side, you won’t have any money to be an alcoholic or drug addict. I’m just sayin.
A lot of truth to that statement
Loud and Fast.
Also hearing protection.
LOL! My boys are gear heads (I think that’s a good thing) they would rather spend money and time on their vehicles than on girls or drugs. I hope they find gear head women who enjoy the same things they do. 
An old friend of mine has a theory he calls “High, Loud, Fast, and Bright.” All enjoyable activities maximize as many of these as possible - racing, shooting, rocketry, fireworks, live sporting events, etc.
I would add “Bright” to both racing (the colorful vehicles) and shooting (the flash at the muzzle end).
I can go with that 
one small problem though… it doesn’t account for girls and horses 
Maybe the combo there is “Big, Powerful, Dangerous, Fast, and Sweet.”
Yeah, that’s in the DNA. Only way to explain it.
The phrase “slow is smooth, smooth is fast” applies to both. I miss racing sometimes.
Fun fun fun.
I saw a post today on my hotrod page. Paraphrasing.
A driver climbs out of his double decker race trailer, grabs a drink out of the refrigerator, stretches out in his lounge chair and grumbles about the costs and pains of keeping a competitive car winning.
In another place, a driver climbs out of his beat up car on his flatbed trailer, grabs a drink out of the ice chest on the grass, sits in his folding chair and grins thinking about how much fun he’s just had.
@OldSchlPunk I thought it was, “If you want to go left, turn right.”
Only dirt track people understand that.
Not only dirt track people, motorcycle riders in general 
As in racing you must be able to hit your marks without fail to win.
Happy Thanksgiving
