Maybe 4-man pit crew... gasman, jackman, and two tire changers who carry their own tires. (If Nascar gets rid of 5-lug wheels, you can thank Tony Stewart for bringing it about.)

If they drop the weight down to 2500-2800 i wonder if they could use air jacks? Get rid of the jackman.
 
I can't get worked up over lug nuts either way. Personally it's not important to me, and it's not why I watch racing. The issues regarding the overall direction NASCAR has chosen with lower HP and high downforce are far more important, to the exclusion of such peripheral concerns. I'd trade tires that fasten themselves or robot pit crews for a reversal on that front.
 
Teams had to find a way to get the times back down after they went from 6 to 5, but they won't be able to with this move. Tire changers are the smaller more agile guys on a crew and now they'll be asked to haul their own heavy tires around while trying to run, slide, and whatever else they do to show off their athleticism? Not gonna do anything but slow it down.
 
It's not the most important thing in the world to me, but wow that will be a change to my viewing experience, hearing the gun on 5 lug nuts is unmistakable at the track and on tv. I always considered it a small differentiator from the other forms of racing.

They could go the way of other motorsports (open wheel) and have tires sitting in stall ready to be lifted on, but I think the stalls are too small in NASCAR for that and pit road is way too crowded with many more cars than Indy or F1 so it wouldn't work. I sure did type a lot to add nothing.

Air jacks work for vehicles that don't beat and bang much. I can see a car getting a blow hard enough to lose containment on the air systems but not hard enough to prevent repairs. When it rolls into the pit box, would they be allowed to bring out a manual jack? How about a crewman to operate it? The six-minute repair window is going to get blown all to bits.

I like technology but it doesn't strike me as a good fit for NASCAR-style stock car racing.

But they only have to loosen and tighten a single nut. They'll be waiting on the gas man.

I must admit that I'm liking what I'm seeing there. IF, and it's a huge IF, they allow the cars to really look like their street counterparts and they can race near each other and pass... This will be a winner. I really like the wheels, so I must be a heretic and will accept my excommunication.
 
Okay, what's a sequential gearbox and what's it's impact on racing?

The only issue I have with 700 lb less downforce is that it isn't 1000 less.

It's pretty much a motorcycle gearbox.

Sorry, that doesn't tell me much. I can identify a motorcycle at a distance of 50 meters 8 times out of 10. That's about the extent of my knowledge, although today I learned they have gearboxes.

simplest definition is that the shift lever is pulled back for upshifts and pushed forward for downshifts. The super cars use them would be one example

So the lever returns to a central position until you're ready to push it up or pull it down again? I'll bet Jr. wishes he'd had that at Pocono.

How do you get into neutral, downshift from first?

Maybe that's why someone wanted it?... save money on blown engines by minimizing bad down shifts.

That's why the military went to automatic transmissions in every new wheeled vehicle since the Hummer. It saves money on clutch and tranny repairs since nobody coming in knows how to drive a manual system.
 
They're going to take all errors and variables away from the pit crews and the cars and the drivers that way we have the most robotic product we've ever seen

I'll disagree with you on this.

Going to a single-lug will mean pit-stops will have to be perfect every time. So many instances in F1, IndyCar, DTM, IMSA, and other forms have single lugs. The gunman screws up the stop and the race can be over for a team because of a loose wheel.

Having five lugs is really a luxury, just like with a road car a loose wheel can be felt out. With a tire vibrating at speed to determine if its loose. With a single lug nut, that will be gone and pit-stops will have to be perfect all the time. If anything it will add more pressure to pit crews to get the stop downpact. Not to mention something like a gun failure during a stop or other mechanical issue with the air hose, compressor, etc.

Then it isn't NASCAR

A small change doesn't recreate an entire sport.

NASCAR will be NASCAR and always will be. Nothing stays the same forever, but some are a bit more open to change. NASCAR has to modernize itself, I love the five-lug stops. It will take some time to adjust, but I'm still going to watch like I always do.

by the same token, taking a rumor and making it real before proof isn't wise

I was responding to @Fordracing7 post as to why I disagreed with the whole point of "robotic stops". Its not true, but giving examples to the mistakes seen in other racing disciplines IF NASCAR decides to go that direction.

This is the part of your post I was commenting on. There have been many things that have been discussed and single lugs is one of them. So far it is nothing but a rumor. Even the chassis they are talking about they haven't named who will make it. Probably getting bids from chassis builders. Five Star has been named to make the bodies..that's a fact

I can only identify them at that ratio at about 50 yards...don't meter anything, I live in the USA.

The US Army lives here too, but all of their rifle range targets are space in meters, and maps are in kilometers. My line was a variation on the format of Army training standards - "Able to do X at a distance of Y meters".

Just because something is what we're used to in the USA doesn't mean it's inherently the best way to do something. The so-called English system of measurements (which even the Brits have abandoned) is ate up with inconsistencies and irrationalities. There's no logical conversion between units. It sucks, continuing by inertia in only three countries: Burma, Liberia, and the US.

Like NASCAR, the US sometimes needs to make changes.

If cost is an issue why on earth would the sanctioning body switch to a single lug setup?

Good idea ... let's scrap a few thousand front hubs and brake rotors while we're getting rid of all the 15" wheels.

How often are they re-used?
