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.
