Product Description

The Wilwood 140-9507-DR is a high-performance rear brake upgrade tailored for Nissan 350Z/370Z and Infiniti G35/G37 models. It features forged DynaPro 4-piston radial-mount calipers finished in red, paired with large 12.88" drilled and vented rotors to deliver strong, reliable braking power.

One of the key advantages of this kit is its retention of the OEM parking brake system. The caliper and rotor combination is designed to offer balanced rear brake bias, ensuring appropriate pedal feel and performance when paired with front upgrades. BP-10 compound pads provide a firm initial bite and consistent braking during everyday driving or more aggressive performance use.

Proper installation requires wheels with at least 17" diameter to clear the calipers and rotors. Overall, this kit is ideal for enthusiasts who want a powerful rear brake solution that looks sporty, performs reliably, and maintains full parking brake functionality.
