제품 잘맞고 유격없이 잘 장착했어요. 아쉬운 점은 이너바렐과 프론티어 레일에 고정시킬 부품이나 오링이 동봉되어있다면 더 좋았을텐데 그부분이 아쉽네요.
배송이랑 안내 모두 친절하게 해주셨고 물건도 완벽하게 도착했습니다

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.
