I suppose my advancing years is responsible for my opinion NASCAR should forget the dirt, COTA and the ROVAL.

For me the jury is still out on Bristol/Dirt. That said, I wonder if NASCAR considered air intakes up higher on the car. I’m sure radiator air intake could have been engineered.

The penalty was based upon an improperly installed wheel/tire. Anyone know exactly what was improper? If the lug wasn’t tight during a pit stop, how would anyone know? Because the lug came off is it assumed it wasn’t installed properly? Could there have been a defective hud or lug? If if it...

The 19 car wore an “Ethyl M” logo, but Kyle’s fire suit and the uniforms of his pit crew the “M & M” logos. Was Ethyl M just a one race sponsor?

Do the teams have and/or rent temporary spaces/shops for the west coast series of races?

Challenger SRT

The last 2 or 3 races I’ve watched have had flyovers, but the aircraft have not been military. Is something going on?

In the first 6 months of 2021 Ford delivered over 30,000 Mustangs. Dodge also delivered 30,000+ Challengers. Chevy only 6,000 Camaros. All this has lead to the belief Chevy is going to drop it. I’m not alone in believing Chevy’s interest in the performance market is waning. If this is so, is...

With the Xfinity race earlier today, I have to assume the cup cars had to be removed from the track, presumably in their haulers. If overnight modifications were not permitted, how did NASCAR insure teams complied. Did officials supervise the loading and the put seals on the haulers?

How/why NASCAR decide on the size (5/8?) for the truck series? Same question w/regard to engine specs.

Rockingham was out first NASCAR race. Still talk about it almost 30 years ago.

SRT Challenger. Generally speaking, you can generally get a deal on any Challenger with a manual transmission. Most everyone wants the automatic. Love the six speed.

Are the new tires the same diameter as the old? Assuming they are (or close), the aspect ratio will obviously be different (numerically lower). In the world of street tires, a “skinnier” tire will result in better traction due to less sidewall flex. And more traction equals more friction which...

Thanks. Great info.

I realize my question and an answer is/would be subjective. Referring to sheet metal, for the sake of this conversation, I’d say factory doors and only mild mods to the leading edge. I’m figuring mid 70’s?

When did NASCAR team's transition from factory sheet metal and suspensions? We're factory suspensions and sheet metal abandoned simultaneously? Did all the team's transition at the same time?

Does anyone have a “cut-a-way” pic of a cup engine? I’m interested in push rod length. I’m told they are relatively short. If so, I’d like to see how it’s done.

Who makes the call as to what tire brings to each race? Is the same tire always brought to the same track? In the case of today’s Kentucky race, would the tire choice change because it’s a day race? What are the odds Hoosier would make another run at NASCAR?

There’s usually commentary w/regard to engine wear at the Coca Cola 600. So, this weekend the cars will be running more than 600 miles. Yesterday I didn’t hear any comments on this. Will we today? Are the engines built with different tolerances when they’re expected to run this long?
