The Electric Kustom Signals SV-1 w/COR Cipher Forged Wheels

Shocking performance and style.

COR wheels have been fitted to almost every kind of luxury, performance, and exotic automobile on the market and have provided these cars with unmatched style and sport. But this is possibly the first ever time that COR wheels have found their way on a one-off, custom-built, electric car.

[singlepic id=2180 w=640 h= float=]

Built in collaboration with Kustom Signals and LIPI (Indonesian Institute of Sciences) the new SV-1 is a fully electric custom-built car designed to provide green performance and audio bliss. The SV-1 is based on the Nissan Cefiro and uses an Advance Series DC 144 V/500 A electric motor to power the rear wheels in combination with 45 lithium ion batteries, each with the same strength as a 3.8-volt battery.

The SV-1 can be charged using a normal outlet or though a charging station. Charging the SV-1 through a household outlet can take six to eight hours, while a charging station finishes the job in a mere 30 minutes. Special solar panels were also installed on the hood of the car to help cool the engine while the car is being operated.

One of the goals for the SV-1 was to keep weight at a minimum. The team was able to achieve this goal by utilizing COR Cipher wheels. These wheels were chosen for their high-strength forged construction and low overall weight. Each wheel was given a hand brushed finish with glimmering chrome lips for a modern style. The COR Cipher forged wheels were installed in a 20 x 12.5 front and rear setup and fitted with 275/40/20 Yokohama Advan Tires, providing the SV-1 with a wide footprint.

One of the other unique aspects of the SV-1 is the sound system used throughout the interior. Alpine supplied each of the four speakers, the subwoofer, and head unit to give the SV-1 a sound system that rivals that of high-end cars. Alpine also provided the team with four monitors that can be configured for entertainment, navigation, and rear view camera use. The entire interior including electronics are water-proof to protect against unexpected precipitation.

The #11 Fisker Tramonto w/COR Wazara Forged Wheels

Handcrafted design and performance.

Fisker may be known throughout the automotive world for the new Karma hybrid sports car, but before the automaker was saving the environment, Henrik Fisker was designing one-of-a-kind sports cars with Fisker Coachbuild. The first design that was put into production was the Fisker Tramonto. Only 15 of the planned 150 models were produced, all of which were manufactured by hand.

[singlepic id=2173 w=640 h= float=]

A handcrafted design such as the Fisker Tramonto deserves only the highest quality forged wheels, which is why COR Wazara rims were chosen for chassis No. 11. The Fisker Tramonto is based on the Mercedes-Benz SL-class and is powered by a handmade supercharged AMG V-8 engine with an output of 610 bhp, allowing for a 0-60 mph sprint of 3.5 seconds and a top speed of 202 mph. The COR Wazara wheels match the power and style of the Tramonto with their handcrafted three-piece forged construction and stunning concave design.

Each COR Wazara is forged using aerospace grade 6061-T6 aluminum alloy to achieve unmatched strength and an incredibly low overall weight. On the high-powered Fisker Tramonto, the COR Wazara wheels were fitted in a staggered 20 x 9 front and 20 x 12.5 rear fitment to ensure all 610 horsepower reaches the pavement. Each wheel is finished with a hand brushed face to match the silver accents on the exterior of the Tramonto.

Although only 15 Fisker Tramonto models were produced, the COR Wazara wheels on chassis No. 11 will ensure that it is a one-of-a-kind automobile for the ages.

Nissan GT-R Featuring COR Encor Forged Wheels

New shoes for Godzilla.

The Nissan GT-R rocked the super car world with unrivaled performance and a Nürburgring lap time that blew the competition out of the water. The Specialized Performance Nissan GT-R is even more potent; packing an 800+ horsepower engine and aerodynamic bodywork. But, the real secret to the car’s success are the COR Encor wheels.

The new COR Encor wheels are more than just your average forged wheel. The Encor wheels undergo a unique weight reduction process that decreases the amount of rotational mass at the wheel hub without sacrificing strength. Each Encor wheel is subjected to  a thorough stress testing process to ensure the wheel is capable of handling the incredible forces exerted by high-horsepower cars.

The exterior of the Nissan GT-R was given a number of carbon fiber aerodynamic additions, but the highlight of the super car is the COR Encor wheels. Each wheel has been given a hand-brushed face with tinted clear coat finish and polished outer lip. This finish complements the contrasting white paint and bare carbon fiber bodywork, but also makes the Encor wheels stand out as the centerpiece of the GT-R. The front axle is fitted with a pair of 20x10s with 265/35/21 performance tires, while the rear features a wider set of 21x11s and 305/30/21 shoes.

3 Piece Wheel Maintenance & Leak Detection


In every day street use, three-piece wheels will provide years of service and require no special maintenance other than standard tire care and valve core replacement at tire change intervals. If you use your wheels for competitions and racing, it is recommended that both 1-piece and 3-piece modular wheels undergo inspection at the end of each season. For monobloc wheels, a thorough cleaning and visual inspection for any signs of stress cracks or fatigue as well as runout checks would be sufficient. If the wheels have undergone any type of impact damage and remained intact, it is strongly recommended that they are x-ray tested or have their finish stripped and undergo a dye penetrant test. The former is the most preferred, but if your preparation for a new season involves refinishing the wheels, the latter may be more practical since the finish will be removed anyway.

Three piece modular wheels require the same periodic maintenance as described above for monobloc wheels. Additionally, since racing involves frequent tire mounting and dismounting, it is also advisable to disassemble, thoroughly inspect, clean, re-seal, and re-torque each wheel.

  • Whenever you disassemble the wheels, it is also necessary that you replace the bolt and nut, and make sure that they are correctly torqued.
  • Proper torque on an 8mm blind bolt is 15 ft/lbs, whereas through bolts with nuts are recommended at 28-30 ft/lbs.
  • Clean the surfaces where the wheel and tire meet with a proper cleaner then apply a skim coat of silicone sealant to the two surfaces, reassemble the wheel, mount, and secure the bolts to the proper torque specifications.
  • Replace the old valve stem with a new unit and install.
  • At the drop center area of the wheel apply a thick layer of silicone sealant and allow it to set and harden for at least 24 hours before the wheel is mounted.

Leak Detection

In the event you come across an issue where you’re losing air, below are some methods to further test where the leak is coming from.

  • Inflate the tire to 40 psi, even if it is above the recommended tire pressure.
  • Mix together soap and water then spray or pour it onto the wheel and tire.
  • Take a tire crayon and highlight where the bubbles form on the tire/wheel.
  • If the bubbles indicate a leak in the wheel or tire, you can reseal the wheel by using the maintenance procedure listed above.

The most popular cause for leaking wheels:

  • Damage to silicone during tire servicing. Being that 3 piece wheels can be a challenge to mount tires on, tire techs must use a tire spoon (in some cases two) in able to manipulate the tire onto the wheel. In the process of handling the tire, the tire spoons come into contact with the barrel of the wheel and if done without extra care, the spoons can come in contact with the silicone causing the silicone to lose its retention and later leak.
  • Use of liquid tire repair agent (fix-a-flat or other). In the unfortunate event of a flat tire, some will resort to a quick fix using a liquid tire repair. The harsh chemicals in these agents can cause two things that will later lead to leaks: 1. The silicone will be damaged with the harsh chemicals causing the wheels to later leak. 2. Some liquids are so harsh that they’ll eat the chrome from the barrels (if chromed) where the tire bead meets the barrel and cause air to escape.

Terry Seibert, Director of the Forged Wheels Division at APP [Interview]

Recently, COR Wheels was able to sit down with Terry Seibert, Director of the Forged Wheels Division at Aluminum Precision Products. Based in Santa Ana, California, Aluminum Precision Products is one of the premier international forging suppliers, and provides COR Wheels with the most advanced forgings in the industry.

What are some of APP’s core values?
Our mission statement is that “Aluminum Precision Products is committed to steady, long term improvement of all our products and processes through defect prevention rather than detection.” Our goal is to be the world class quality supplier of choice in the forging industry.

How long has APP been in business?
We were established in 1965.

What are some of the biggest changes you’ve seen or experienced in the forging industry during the past ten years?
More exotic light weight alloys are being developed and tested. Multi-piece or segmented precision die designs are also becoming more prevalent. APP is one of the premiere forge houses in this part of the industry.

Where do you see the future of the forging industry in ten years?
Expansion of forgings used in aerospace will continue to increase. Plus, the automobile industry will grow exponentially as cars are mandated for higher and higher CAFÉ numbers; vehicles will need to be light weight in all areas large and small such as suspensions, pistons, con-rods, engine components, structural components, and of course, wheels. We have a very positive outlook for considerable growth in the future.


What are some future plans for APP?
APP will continue as outlined in our mission statement, as well as expand in currently supplied aerospace, automotive, military/defense, medical, scuba, and commercial industries by expansion of sales and further acquisitions of cohesive like-manufacturing facilities.

What differentiates your forgings from others?
Our expertise garnered from engineering design, the calculation of grain flow appropriate to the part to be forged, and use of appropriate tonnage from one of 58 forge presses for a specific forged part. With our in-house die shop capabilities, we also ensure the customer is getting the best forgings.

What automakers use your forgings as Original Equipment (OE)?
Automakers such as Ferrari, Lamborghini, Aston Martin, Mercedes-Benz AMG, Pagani, Ducati, Artega, Koenigsegg, Alfa Romeo, and Audi use our forgings as Original Equipment.

Where are your forgings developed?
All engineering design, forge die production, forging processes, and spinning are performed in Santa Ana, California USA.

Differentiate Rotary VS Conventional Forgings?
APP is now, and always has been, a proponent of conventional forgings versus rotary forging for a general reason; that being the fact that APP does not forge only “round” parts. Our process includes precision forging of a variety of shapes and complicated designs. Specifically, APP believes the correct grain flow and direction of the grain flow for strength is obtained via conventional hydraulic forging versus pushing metal in a circular motion to obtain a round shape.

Sexy Styling With More Than 1,000 Horsepower To Back It Up

Lamborghinis have always been extreme and excessive with their styling and performance. After all, their logo is a charging bull. So, when Bill Levinson decided to take his Gallardo to a new level of performance; he knew that unleashing this already raging machine would require the very best parts and performance products, and not to mention; experienced technicians to get the job done right. After enlisting the help of renowned Lamborghini tuner, Heffner Performance, to turn the already potent V-10 into a dyno monster, Bill entrusted his 1,000-horsepower Gallardo Spyder to the team at COR Forged in order ensure that his untamed bull would leave with ferocious style and performance.

The hooves of this Gallardo Spyder are fitted with a set of F1 Brava wheels with a matte black finish from our Competition Series Collection. The high-strength forged aluminum construction helps these wheels reduce unsprung mass, while dramatically increasing strength to withstand the enormous stress generated by the powerful engine and the competition rubber. The Gallardo boasts a widened stance with the F1 Brava wheels, measuring 20 x 8.5 inches up front and 20 x 12 inches at the rear axle. To help put all 1,000 horses to the pavement without erupting in a cloud of smoke, the stunning wheels wear ultra-sticky 245/30-20 and 315/25-20 Michelin Sport Cup tires.

Bill L. Levinson has been one of our best customers. You may recognize him from the 12-page feature in Heavy Hitters magazine titled “The Powerhouse”. As head of one of the Top 10 Life Insurance Marketing Companies in the United States, Bill, just like his Gallardo, is no stranger to a fast-paced, dynamic, and rewarding lifestyle. But, there’s more to Bill than his successful insurance marketing business. Bill is also a firm believer in health and exercise, and spends at least two hours a day at the gym working on bodybuilding and maintaining his physical fitness. He is a firm believer that there is a direct correlation between the discipline of working out and the direct impact it has had on a person’s success. It is the same internalized power of discipline which ultimately replaces procrastination with accomplishment, and complacency with determination.

Bill Levinson’s Lamborghini Gallardo Spyder hides a force-fed V-10 tuned by Heffner Performance. The twin-turbocharged 1,000 TTG engine build from Heffner consists of twin ball bearing turbochargers, upgraded fuel and engine management systems, reinforced engine internals, and upgraded drivetrain components. The result is 1,000 horsepower and blistering acceleration times of 3.1 seconds to 60 mph and 21.2 seconds to 200 mph. With the 1,000 TTG kit, the Gallardo Spyder can scream through the quarter-mile in just 10.3 seconds at 144 mph – all while riding on a set of striking COR F1 Brava wheels.

Cast Wheels VS Forged Wheels, What’s the difference?

The terms “forged” and “cast” are often used to describe a set of wheels to indicate the process used to manufacture the wheel. In the wheel industry forging and casting are the two predominant types of processes used to manufacture wheels.

During the casting process molten aluminum is either poured or drawn using a vacuum into a mold, where it is formed into the desired wheel shape and allowed to cool. Once the wheel has cooled minor modifications such as drilling and trimming are made, allowing for quick and inexpensive production. While a cast wheel may be easier and less expensive to manufacture, the process of allowing the molten aluminum to solidify leads to porosity, which are essentially inconsistencies in the material structure that unaccounted for can lead to cracking, oxidation, pitting in the finishing, and a reduction in the wheel’s structural integrity. To counteract this deficiency, manufacturers are forced to design with larger tolerances which lead to heavier wheels in order to achieve the desired structural integrity.

In contrast to casting, a forged wheel begins as a solid piece of metal referred to as a “billet”. This billet is then subjected to heat and intense pressure, which compresses the material to form a raw forging. These raw forgings are “forged” into different profiles to allow for the creation of different wheel designs.

The raw forgings are then lathe turned and milled in-house using our CNC machines to form the final shape and application of the desired wheel.

Due to the immense pressure that the billet undergoes during the forging process, the metal is less porous compared to cast wheels and has an interlocking and aligned grain structure. Although this can only be viewed under a microscope, this structure results in improved strength, durability, and resistance to corrosion and oxidation. Due to the more consistent forging, the same structural integrity can be achieved using less material in a forged wheel versus a similarly designed cast wheel, this lighter weight translates into improved overall vehicle performance. Forged wheels are often made into traditional one-piece monobloc wheels, or due to their inherent strength to weight, they can be made into two- and three-piece variations to give manufactures enormous flexibility in creating custom offsets and widths that would not normally be available in a monobloc construction.

Although the forging process may be more time consuming and costly than cast wheels, they offer significant benefits to the consumer. COR and Axiom wheels are designed and machined in-house, which means we have extensive control over the manufacturing process ensuring the highest level of quality and craftsmanship. In general, our forged wheels offer a 10 to 15 percent reduction in weight compared to factory cast wheels with some examples achieving a 35 percent reduction in weight.*

So, if you’re looking to upgrade your set of factory cast wheels, our forged wheels will not only improve the look of your vehicle, but contribute to an increased level of performance by reducing unsprung weight, while providing unmatched strength, durability, and, of course, individual style.

* Please note the exact weight reduction will be dependent on the factory wheel style and the wheel being used for the upgrade.
