Brembo Gran Turismo Front Big Brake Kit for Porsche 930 (1978–1979) | 7004A Series

This Brembo Gran Turismo Front Big Brake Kit (7004A series) is a front axle upgrade for Porsche 930 (1978–1979), replacing the factory braking system with a fixed 4-piston Brembo caliper and 332mm x 32mm two-piece rotor setup. It addresses the fade and pedal instability that show up when the factory brakes are pushed beyond normal street use.

This configuration is typically used on street-driven or lightly performance-oriented 930 builds where improved braking consistency is needed without stepping into larger high-capacity systems. The 332mm rotor package increases thermal capacity over stock while maintaining easier wheel compatibility compared to larger setups. It’s commonly installed during brake refreshes or when improving pedal confidence under repeated use.

When it comes to bigger brakes, Brembo is the name most people end up at for a reason. This kit includes a pair of GT 4-piston cast monobloc radial mount calipers loaded with Brembo FM1000 pads set up for street and performance use. It’s paired with high carbon two-piece rotors—available in Cross Drilled or TY1 configurations depending on the selected variant—with corrosion-resistant plating, along with Goodrich braided lines and CNC billet radial mounting hardware.

Add it up—4-piston calipers, 332mm rotors, braided lines, and the mounting hardware to tie it all together. This is the entry point into a Brembo GT system for 930 owners looking to improve braking consistency without moving into larger multi-piston setups.

Fitment & Compatibility

Fits Porsche 930 models from 1978–1979. This kit replaces the factory front braking system with a Brembo caliper and rotor package.

IMPORTANT: Before you purchase a Brembo Performance or Racing Brake system you should always confirm that the vehicle's wheels have adequate clearance, regardless of wheel size.
