[Description]
Rear disc developed jointly by Grip Trading and SUNSTAR for BMW!
âSpecial steel SUS410DB is used as material
These disc rotors are made of SUS410DB, a martensitic stainless steel specially designed for BMW disc rotors, to provide stable braking and peace of mind.
âHigh potential heat capacity
This product is designed to improve the heat resistance of BMW rear rotors, which are structurally less exposed to wind and more susceptible to heat buildup.
âHoles & Slits
The synergistic effect of the holes and slits designed into the rotor provides a good brake feel.The hole ensures lightness and heat dissipation, and the slit provides cleaning and heat dissipation assistance.
âJapanese precision
All the machining is done at SUNSTAR's own factory in Japan, and it is produced with priority on accuracy by fully investing the world's leading mass production technology.In order to assure the safety of "braking", all products are inspected for accuracy even if it costs a lot.
