We can define frictions as the Resistance to the movement of one body in relation to another body with which is in contact. If we try to slide a wooden block across a table then friction acts in the opposite direction to the movement of the block.
The forces that slow down a racing car are:GravityAir ResistanceFrictionAerodynamic Downforcethat's the 4 forces
About 130?
So they don't topple over when they are taking turns.
(Before I answer this question, I will restate it to "Which tires create the most friction?".) In racing, super soft racing tires usually create the most friction on road. They give wind to durability, but require only several turns to heat up.

Helmets were important to the Romans because they protected the head and prevented many serious injuries, just as helmets today protect those wearing them. The Romans used helmets for much the same purposes as we do, such as, in the military, in chariot racing and in gladiatorial combats.Helmets were important to the Romans because they protected the head and prevented many serious injuries, just as helmets today protect those wearing them.

Auto racing helmets cannot be used for street bicycling or motorcycling, at least in many jurisdictions where minimum visual field requirements exist for a street legal helmet.Although auto racing helmets are similar in construction to motorcycle helmets and provide the same level of protection, they have a number of essential differences besides possessing fire protection required in ultra-high-speed car crashes:Car racing helmets are designed more for repeated impacts in a single place since a securely held racing driver will not move. In contrast, during a motorcycle crash the rider will hit his or her head in many places.Car racing helmets are shaped a little differently from motorcycle helmets because most hits are to the top of the driver's head rather than the front or the sides as in a motorcycle helmet. The full-face protection on a race car helmet will not extend as low on the face as in a motorcycle helmet.Race car helmets have very narrow visual fields. This means that if used on a street bike the rider could quite possibly not see a vehicle coming in from the side.These three features mean an auto racing helmet is not going to provide optimum protection for a motorcycle or bicycle rider on a public street, and could even be dangerous because it is so hard to see out of.

It depends what type of racing they are doing. In a Time trial there are specific Aero helmets that many prefer. In touring a long distance road riding a light comfort helmet is preferred it's very dependent and also has to do with preference.
