Brembo Gran Turismo High-Capacity Front Big Brake Kit for Porsche 930 (1978–1979) | 8071A Series

This Brembo Gran Turismo High-Capacity Front Big Brake Kit (8071A series) is a front axle upgrade for Porsche 930 (1978–1979), replacing the factory braking system with a fixed Brembo multi-piston caliper and larger 355mm x 32mm rotor package built to maintain braking consistency under repeated load. It addresses the fade and pedal instability that show up once the factory brakes are pushed beyond normal street use.

This setup is typically used on harder-driven 930 builds where repeated high-speed stops or aggressive driving begin to expose the limits of the stock system. The increased rotor mass and caliper stiffness help maintain even pad contact and consistent braking force as temperatures rise. It’s a common upgrade for cars that see canyon driving, fast road use, or track time where heat control becomes a factor.

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 multi-piston cast monobloc radial mount calipers loaded with Brembo FM1000 pads set up for street and performance use. It’s paired with high carbon rotors—available in Cross Drilled, TY1, or TY3 configurations depending on the selected variant—with corrosion-resistant plating, along with Goodridge braided lines and CNC billet radial mounting hardware.

Add it up—larger rotors, multi-piston calipers, braided lines, and the mounting hardware to tie it all together. This is where 930 builds land when the factory braking system can’t keep up with sustained use.

Fitment & Compatibility

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