JOES T Nuts Kit for Rotor Flange

JOES T-Nut System and Rotor Flange improve your braking efficiency.
Hardened T-Nuts self center in the rotor flange. The small amount of
movement allows your rotor to grow and shrink through heat expansion. As
the rotor heats and cools the T-Nuts prevent warping related to heat
expansion resulting in a smooth and firm pedal throughout the race. Pads
last longer and rotor life is improved. Better braking gets you deeper
into the corners. Bolt size is 5/16-24 and should be torqued to 20 ft lbs. Sold in a packs of 8.
