JUN could achieve manufacturing its original flywheels about 200% more strength compared with normal flywheels. It was forged using Chrome-molybdenum steel. The power of inertia rotation can be decreased by reducing the excess weight, and therefore, its strength directly passed through to the high response.
JUN Ultra Light Weight Flywheel is targeted the customers who regard the higher rotation area for their highly modified engines. This flywheel is also designed to be strong as well as light-weight, and forged using Chrome-molybdenum steel.
The engine response improves if a flywheel is made light that is often said. In case of revolving thing like a flywheel, the power (inertia power) which is always going to continue fixed rotation occurs. An engine tries to increase the number of rotation when you pedal an accelerator, but a flywheel tends to keep an idling state according to its inertia power. When inertia power becomes large, much time is needed for going up rotation. In the case of the JUN lightweight flywheel, since weight (especially flywheel perimeter part) is light, there is little inertia power of influencing rotation of engine. Since time to go up rotation is shortened, the response of engine to a accelerator becomes quick (a response improves).
The JUN light weight flywheel is made from the optimal weight and optimal form which were set up for each type of a car from the chrome forge material. By shaving all circumference of the chrome forge material, the variation in weight and the deviation of balance are pressed down to the minimum. Processing for raising wear durability and heat treatment etc... is performed in the surface. Various know-how for realizing lightness, strength, and high balance is condensed to the JUN light weight flywheel.

Jun is widely recognized in the automotive world as a Japanese tuner and has created some of the fastest sports compact cars in the 90s. Originally, the company started in 1946 manufacturing engine parts for the internal combustion engine. Today, after more than 70 years in the business, JUN has consistently provided high-performance parts and has turned ordinary vehicles into fast and reliable performance street machines.
JUN Auto has actively participated in races in Japan. During the 90s, they have participated in the All Japan GT Cup, which is considered as one of the most prestigious events in Japan. They did not only race in Japan but went all over the world, conquering the salt lake flats in the US and races in Hockenheimring in Europe. Using the experience they got from joining these races, they were able to translate it into their products, creating parts that could bring out the best in any vehicle.
The company has grown since it first started in Japan. Its popularity has gone worldwide that they established branches all over the world, creating, JUN AUTO Thailand and JUN USA. They have also participated in auto shows from different countries showcasing their products. Some of these shows are SEMA in the US and Tokyo Auto Salon in Japan.
If you are in search of quality performance parts that are proven both on the streets, in car shows and on the track, then JUN Auto is the brand for you. They specialize in internal engine upgrades but also offer external pieces and aero kits as well. Visit Vivid Racing and check out the list of their products that would fit your specific needs.
