The DBA X Gold Street Series front drilled and slotted rotor for 2006–2008 BMW Z4 (E85/E86) uses a non-directional cross-drilled and slotted pattern to increase exit points for pad dust and gases, improving pad bite and consistency. Favored for open-wheel and show cars for its gold hub finish, it serves as a direct-replacement that balances visual appeal with enhanced ventilation; the T2 slot is suggested for heavier braking.
