GIRODISC A1-292 Front Brake Rotor Kit for BMW M235iR / M240iR

GiroDisc brake rotors are designed as direct replacements for factory components, requiring no modifications. They install onto the vehicle using the original calipers, maintaining factory brake bias and proper ABS function. This is the ideal solution for enhancing braking performance without altering the system's geometry.

The rotor hat is precision machined from 6061-T6 aircraft-grade aluminum, sourced exclusively from the USA. The friction ring is crafted from GiroDisc's proprietary cast iron, cast and machined in their own US-based manufacturing facility. The curved vane design ensures efficient cooling through a centrifugal effect.

The floating mount system features ten cadmium-plated, high-tensile steel standoffs, allowing the rotor to expand freely under heat while maintaining precise positioning. Anti-knockback springs eliminate rattle at low temperatures and ensure the rotor stays centered between the pads.
