Comments about Audi A7 C8 (2018-2021)

It got 7/10 points on TopGear, and the over verdict is “This isn’t a luxury sports saloon – it’s a luxury limousine dressed in a rakish, designer suit” Audis always pay more attention to detail, often more than absolute driving pin-sharpness. An S and RS car from Audi is much more than HP and torque. They drive, sound, and handle differently compared to the A-range.
An S-car (and RS-car) will have more powerful brakes, stiffer suspension setups, carbon-fiber interior trim. All these things contribute to a dynamic/sporty drive. While a car from the A-range like the A7 is definitely aiming for comfort and luxury.

Aftermarket Wheels and Wheel Bolts Pattern

When referring to any and all-wheel fasteners, stop using the generic term “lug nut “. Not all vehicles use nuts. Many German vehicles use bolts instead. therefore, it is inaccurate to often refer to all-wheel fasteners as “lug nuts.

What does Wheel Seat mean?

The “seat” refers to the contact area between the base of the fastener head and the wheel´s fastener pocket. Although variations exist, three basic seat styles are in common use today: conical, ball, and flat-seat types. Most of the aftermarket rims adopt a conical wheel seat pattern.

  • Conical wheel nuts (or wheel bolts) feature a straight taper at the seating area. Conical fasteners are also called “tapered” or “cone” types. All of them refer to the same style.
  • Ball seats also are called “radius” or “rounded” seats. As the name implies, the seat features a radiused “ball” shape that nestles into a ball-shaped pocket in the wheel. Many European vehicles such as Porsche and Mercedes use radius seat styles, in either nut or bolt applications.
  • The flat-seat style is most often called a “mag” style. The term “mag” doesn´t imply anything in terms of geometric shape. It´s simply a slang carryover from the early days of the American performance scene when race wheels were cast magnesium and commonly used a flat seat because it was easier and cheaper to produce a round hole in a flat hub center area.
