Brembo GT Hardware Pack 105715930 – Bolt Kit for 2-Piece Rotors

Brembo GT Hardware Pack 105.7159.30 – Bolt Kit for Floating 2-Piece Rotors

The Brembo hardware pack 105715930 (alternative number 105.7159.30) is the genuine bolt kit that connects the friction ring and aluminium hat of a 2-piece Brembo Gran Turismo (GT) rotor in a floating mount. It fits rotors sized Ø 328 x 28 mm, Ø 345 x 28 mm, Ø 380 x 28 mm and Ø 330 x 34 mm.

The floating connection lets the friction ring expand radially and axially at high temperature without stressing the hat. This protects against coning, lateral runout and heat cracks. Whenever the friction ring is replaced, the hardware should be replaced as well.
