Jap, European, and American brands too, such as Tein, HKS, Cusco Ohlins, Koni, KW, Bilstein, Penske, Dynamics/Multimatic, Sachs, JRZ, GAZ, etc all utilise Jap/European/American design, development and manufacture.
the quality is high, sometimes so are there prices.
D2, KSport, Megan, F2, G4, HSD, BC Racing, XYZ etc are all designed,
"developed"
(i say it in inverted commas because there isnt any car-specific testing and development, which is why the damping imo is so poor) and manufactured in Taiwan and China.
the problems arent a function of poor manufacturing standards, they are a function of the people designing them having no idea what damping a car requires for good performance needed for that percific aplication, comfort and durability, and genrally targeting profits over quality.
the top Jap European and American brands have a long history in dampers, As they have been exstensivly developed in race aplication on each percific car they were intended for, that is the difference in quality and performance.
The easiest way i could summarise it is to say that a UK company could make a television, and a Taiwanese company could make one that was just as good.
but if a Taiwanese company tried to build a Formula 1 car the same as the Brawn GP from this season they would fail, miserably.
the reason being that there is decades of knowledge and experience behind the success of an F1 team, and the same applies to the components on the car
(e.g.
dampers in this case).
you cant just manufacture something based on simple ideas and visual appearance and expect it to perform the same as the products from companies that have been doing it for decades at the highest levels of motorsport
(which is where pretty much ALL of the major development occurs).
what kind of serious motorsport does Taiwan etc have none atall.
Trust me dude if its a track car you really do get what you pay for
.
hope this helps
