Brembo GT-S Hard Anodized Rear Big Brake Kit for Porsche 993 C2/C4 (1995–1998) | 8019AS Series

This Brembo GT-S Hard Anodized Rear Big Brake Kit (8019AS series) is a rear axle upgrade for Porsche 993 Carrera 2 and Carrera 4 models (1995–1998), replacing the factory braking system with a fixed 4-piston Brembo caliper and 345mm x 28mm two-piece rotor setup. It improves rear braking stability and heat management, especially on cars where the factory rear system begins to fall behind under repeated braking.

On 993 builds, rear brake performance becomes more noticeable once front braking capacity is increased or the car is driven harder. The factory rear setup can struggle to keep pace, leading to imbalance or inconsistent braking behavior. This kit addresses that by increasing rotor mass and improving caliper rigidity, helping maintain consistent rear braking contribution during repeated stops.

Brembo’s GT-S line uses hard anodized calipers for improved durability and resistance to heat-related wear, paired with the same core engineering used in their OEM and motorsport systems. This kit includes GT 4-piston cast monobloc radial mount calipers loaded with Brembo FM1000 pads for street and performance use. It’s paired with high carbon two-piece rotors—available in Cross Drilled, TY1, or TY3 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 rear calipers, 345mm rotors, braided lines, and proper mounting hardware. This is a common upgrade when bringing the rear system in line with increased front braking performance.

Fitment & Compatibility

Fits Porsche 993 Carrera 2 and Carrera 4 models from 1995–1998. This kit replaces the factory rear 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.
