배송이랑 안내 모두 친절하게 해주셨고 물건도 완벽하게 도착했습니다
依頼から受け取りまでとてもスムーズかつスピーディーに対応して頂きました。
결국은 다 사게될 부품들, 드레곤볼 모으듯 신경 쓸 필요가 없습니다. (아마 더 쌀껄요?)
규제에 맞추기 위해 명시해주신 내용은 매우 중요한 힌트였고, 만족스럽게 튜닝 끝마쳤습니다.
This is a reinforced piston specially designed for DSG. The rack gear has 9 teeth and is compatible with both 8T and 9TDSG.
The body is made of injection-molded fiber-reinforced nylon, and the rack gear is made of fully machined spring steel (56SiCr7) and heat-treated to a hardness of HRC50.
The teeth are designed to prevent piston crashes, with the second tooth missing from the start of engagement and the third tooth being half the height. 
Taking advantage of the fact that the stroke only goes back by the length of 9 teeth,
The overall length of the piston has been extended, and the rack gear receiving part is thicker than a normal piston.
It weighs 17.8g and the spring is compatible with the standard Φ15mm standard.
