My wife got a private tour of a Nascar team owner's operations and I learned a few cool things from it-

The cars cost around $250k for the initial build and there are between 30 and 40 in production for this team.

The axles are tilted sideways so the car automatically turns left without steering.

On a good day with a well tuned car, you never have to turn the steering wheel on a full lap at Lowes Motor Sppedway.


One of my neighbors does the engineering/testing on the NASCAR (ford) steering actuators, so I've seen the level of detail that goes into the smallest of processes.


As a non fabricator, I'm always amazed at the evolution of racing through engineering, design, and sometimes just late at night drinking ideas.
 
So.... is this a question or general statement of wonder?

They also have camber on the rear wheels
 
I know on the open wheel modified cars the rear axle is designed to swing in the curves then straightens back out in the straight stretch. Guys I've talked to swear theyre easier to drive than most other classes.
 
@Hurley Was that "centrifugal" with the British pronounciation or the American pronounciation?
 
I know while working at BMS that the drivers looked like they were having a hell of a time keeping their cars straight in the pits As apposed to the actual track! Hope that NASCAR experience gives ya a boost in hammertown, Bring it home for The Eastcoast 4x4!!

I knew when I had my sprint car set up right for me when I couldn't turn right out of the entry chute.

It's all about the centrifugal force.

Do you think it's the centrifugal force that does that? Kinda like how those motorcycles in the cage use centrifugal force to go around and upside down. Centrifugal force is pretty cool I think.
 
Just had to throw that in @Hurley 's direction.

I'll let the giant brains reason amongst themselves. I've got nothing to contribute.

Back when I raced a 6 cyl pure stock car, all kinds of steering was involved- right, left, and everything in between. Must have way been beyond critical speed- ludicrous speed or something.
 
If you're going hard enough left, you'll find yourself turning right.

As Benny Parsons said, a tight car is when you see the wall when you hit it, a loose car is when you don't see the wall when you hit it.

True statement, one that applies to both dirt and asphalt.

As a buddy in nasar once said
A tight car - you enter the corner, turn left and the car goes straight.
A good car - you enter the corner and turn right and the car corners
A loose car - you enter the corner and turn right and the car turns left

My car you enter the corner and it dont atter what I do I dont have a fawking clue what it is going to do.
 
Reading comprehension is crucial.
I didnt say that, a friend did who used to drive for a truck team and now works on the 48 car did
