Which Porsche models come with center lock wheels?
Center lock wheels are standard on the 992 911 GTS, GT3, and Turbo S models. As a result of the huge torque wrench and breaker bar arrangement required to install and remove the wheels, they are regarded as being challenging. In order to perform it correctly, you must also adhere to the Porsche protocol.
Porsche uses centerlock, but why?
Wheels with center locks are not frequently found in street-driven vehicles. They are difficult to remove should you suffer a flat since they take a lot of torque to tighten. The layout is advantageous for racing since it allows for larger brakes because the central lock hub is smaller. Porsche uses center lock wheels on the GT3 and Turbo S, extreme variants of the 911, but we’ve never seen similar technology on the vastly bigger Panamera sedan. Before now.
The car seen in these spy shots isn’t a production model, just to be clear. With new bodywork covered in black tape and camouflage panels, it is obviously a prototype. It’s also possible that this is a test mule being used to evaluate center lock hubs for usage in a different model. But we also need to take into account the potential that Porsche is developing a Panamera sedan that will join the lineup for the following generation. Given that the current Panamera already approaches 700 horsepower (522 kilowatts) in Turbo S E-Hybrid trim, that is an intriguing claim.
What should I do if my wheel lock key is lost?
Even if it occasionally costs more, this is the choice that is easiest to choose. However, you’ll need to purchase a new locking wheel nut key if you want to use the original locking wheel nut set.
Each key has a code that allows you to order an extra from the car’s maker. The locking wheel nut storage box or plastic storage bag is the only way to find this code, thus it’s an issue if those are also missing!
The sameness of centerlock wheels
Except for the way they are bolted to the wheel hub, center lock wheels are identical to normal wheels. A center lock wheel employs a single big nut right in the middle, whereas traditional wheels use five or six lug nuts evenly spaced from the center. Utilizing a center lock nut has a few benefits, but there are a number of drawbacks as well.
The first and most significant benefit is how much quicker a wheel can be removed using a central lock. A typical wheel can be removed in 1/5 to 1/6 the time with a center locking nut. Even though the ordinary person may not think much of this, in the world of motorsports, it can mean the difference between winning and losing a race. Greater space between the wheel and wheel hub is also made possible by the employment of a single center nut. The additional room can be utilized to install bigger brake disks and calipers. Once more, the increased stopping power is a considerable advantage for both race vehicles and sports cars. Car aficionados are drawn to center lock wheels because of its aesthetic appeal and the oohs and ahhs they elicit from onlookers.
There are a few disadvantages to center lock wheels, so hold off on buying them just now. The main disadvantage is how challenging it is, without the proper power equipment, to install and remove a center lock wheel. A center luck nut demands 450 pound-feet of torque, as opposed to the typical lug nut’s 90 pound-feet. Hand tools simply won’t do the trick if you’re an ordinary torque wrench. To tighten and loosen the middle lock nut, grown men with ordinary build would have to exert their entire body weight and more. The wheel will likely fall off if the torque is improper. For this reason, an air compressor and pneumatic torque wrench are typically advised. Center lock wheels are pricey as well, as if a pneumatic torque wrench and air compressor weren’t expensive enough enough. The cost of center lock wheels is often two to three times that of regular wheels of equivalent size. Usually, this results from low manufacturing volumes.
Center lock wheels are not that uncommon on the road, despite the fact that they are typically found on race cars like those used in the Le Mans 24 Hours, Formula 1, and IndyCar. Some automakers have offered center lock wheels as a factory option for their production models. For almost 20 years, Porsche has used center lock wheels on its top models, most notably the 911 GT3, Carrera GT, and 918. Center lock wheels were also a feature on Ferrari’s F40, F50, Enzo, and LaFerrari. The center lock wheels have been used on every Koenigsegg production car.
The majority of people may be surprised to hear that low-riders have center lock wheels. They employ “knockoffs,” or slightly different center lock wheels, but they function on the same principles. The term “knock-off” refers to a center nut that must be physically struck with a mallet because it is winged. The mallet’s assistance allows for the achievement of the necessary torque.

Centerlock wheels—are they better?
Rudge-Whitworth invented the centerlock wheel and hub system in the early 1900s for use in wire wheels for automobiles. The fundamental mechanism for “knock-off” style centerlock hubs was invented by 1908 and was first known as “QD” (for “quickly disconnectable”). Automakers and racers embraced it very soon. Despite the fact that safety concerns prevented Rudge-Whitworth knockoff hubs from being utilized in the 1908 French Grand Prix, the technology had become standard in Grand Prix auto racing by 1913.
The Rudge-Whitworth “knock off” wheel and hub design was licensed by Carlo Borrani in 1922, and he established his own business to produce them. Originally known as Rudge-Whitworth Milano, this business changed its name to Carlo Borrani, S.p.A. in the late 1930s. The knock-off wheel/hub design was made more well-known by Borrani wire wheels, which were used in numerous successful race and road cars. Instead of using steel, their design employed aluminum alloy rims, which improved unsprung mass and hence total performance. Alfa Romeo, Isotta Fraschini, Fiat, Lancia, Porsche, Mercedes-Benz, and Auto Union were among the first manufacturers to purchase wheels from Borrani. These wheels were also installed on numerous Ferrari road and race vehicles throughout the post-war era, among other makes.
Road automobile safety requirements in Germany and the United States in the late 1960s forced the removal of the distinguishing wings or “ears” on replica hub nuts. Some manufacturers continued to use the Rudge-Whitworth pattern-based internal design, but they fastened it with a hex nut instead. Centerlock hubs were increasingly phased out in favor of 4-, 5-, or 6-lug nut wheel fastening systems in road car design.
Even though the mechanical specifications of the design subsequently diverged from the original Rudge-Whitworth pattern, Centerlock wheels and hubs were nevertheless utilized for racing cars. A sort of centerlock hub is used in many different types of racing, including Formula One, sports car racing, NASCAR (Cup Series seventh-generation car, starting in 2022), and many more. Centerlock wheels and hubs are more suitable for racing than lug nuts because they can be taken off and put back on more quickly during pit stops, allow for hub designs with larger spaces for brake discs, and have more strength when properly mounted. Some automakers and tuners fit centerlock wheel and hub systems to road-going sports cars due to the centerlock’s enduring link with racing and high performance.

Do Porsche Cayenne’s tires have run flats?
My Cayenne or Boxster don’t have any run flats. Both have a compressor and tire sealant. Since there is nowhere to lay the flat tire, the Boxster has no spare. In Cayenne, the spare tire is inflatable.
How is a Porsche Cayenne jacked up?
Slowly lower the car after securing the jack stand underneath the jack support region. Place a jack stand under the front reinforced plate if you’re lifting the front of the car, then lower it onto the jack stand. Repeat for the opposite side of the car.
What exactly are replica wheels?
Wheel knockoffs are made to tighten as they turn. As the car is driven, the wheel on the driver’s side turns counterclockwise. Righthand threading on the imitation spinner causes it to tighten as the automobile moves forward. As the car is driven, the passenger-side wheel turns in a clockwise direction.
Are the center lock and six bolt interchangeable?
They can both be used interchangeably. As long as a suitable adapter is used, it is less expensive to convert a center lock to 6 bolts than it is to convert 6 bolts to a center lock because a new wheel hub is required.
The locking wheel nut was wholly original.
A MECHANIC who created a life-saving wagon warning device is jubilant after winning a court dispute over the device’s revenue.
The little plastic signs that instantly alert drivers that the wheel nuts on their bus or lorry are securely fastened before they depart were invented by Pete Brawley.
For HGV drivers across the nation, the device that attaches to the nut is now a commonplace.
However, Pete developed the idea that is today hailed as a crucial life-saver 11 years ago.
“I was a self-employed mechanic working on other people’s lorries,” said Pete from Worsley. Wheel nut loosening or shearing off due to overtightening was a persistent issue for us.
Experts calculated that 10 persons were killed in collisions every year as a result of a wheel coming off their car.
“One evening, after a long day of tackling the issue, I arrived home and watched a program about innovators. I then made the decision that I was going to come up with something and establish myself as an inventor.
I thought about what I could create to make life simpler, and one night as I lay in bed, the wheel nut indicator came to me. At two in the morning, I leapt out of bed and immediately drew the initial design.
Pete was developing lorries at the time for the regional invention clearinghouse Business Lines Ltd.
He pitched his idea to Michael Marczynski, the company’s owner, who agreed to help with the development costs if he could be listed as a co-inventor.
I agreed because I didn’t know anything about inventions or patents, stated Pete. But the invention had already been registered to Business Lines when I was investigating it.
Pete decided to file a lawsuit after Business Lines resisted giving up the invention’s patent and paying him his portion of the profits.
And now Pete has obtained patent rights and a sizeable out-of-court settlement with the aid of the law firm DLA and forensic accountants Pierce.
He has been working on new innovations behind closed doors, and he is now resolved to invest the money in them.
“I can’t retire on the money I’ve won, but it’s a considerable amount,” he remarked. For obvious reasons, I can’t yet share specifics about my other inventions, which are mostly for the drainage sector.
“This new wheel nut indication was Mr. Brawley’s invention and it has had a tremendous influence on the safety of lorries and buses,” said Pete’s attorney Mark Goodwin of DLA.
