Due to many requests for Prius use with this grip, we manufactured it by helicoil processing for M6, which was impossible because Φ6 was open. Tapped on a Mac Tools driver grip (DG11).

(Black, Green, Red, Yellow, Orange) M6 type Mac grips are available in 3 types in the 7th photo. KTC grips are also available. As a precaution during installation, completely remove any thread lock attached to the male threads on the vehicle side. The height of the grip is approximately 90mm.
