Here is an article about a replica that was made of Fireball Robert's 1957 Ford NASCAR stock car.
What I found interesting were some of the features of the car, such as:
1. Vertical piece of wood mounted to stop Roberts sliding in the seat.
2. Firewall trap door so that the wear on the right front tyre could be checked during a race.
3. Leather strap to hold the transmission in second gear.
These features were not considered "cheating", but just things used to make the driver more comfortable, or the car safer.
This got me thinking about such features in other cars, such as:
1. Tilting of a tachometer in the instrument panel so that the safe rev limit appears at 12 o'clock, which the driver could immediately recognise.
2. A strip of tape placed at 12 o'clock on a steering wheel, so that the driver has a visual indicator of how far the wheels are turned.
3. Tubing mounted on the door of a sedan to blow air into the cockpit.
I would be interested in any other similar/unusual features that forum members have noticed in racing cars that they have seen.
