Description

The Ksport Supercomp Big Brake Kit represents their most extreme brake upgrade, engineered to deliver unparalleled stopping power for the Nissan 300ZX (1990-1998) without requiring any modifications to your vehicle. This sophisticated, bolt-on system enhances performance by incorporating larger calipers, rotors, and brake pads, along with an increased number of pistons. Standard full-floating rotors are included to ensure optimal self-centering within the caliper, thereby reducing drag and promoting more even brake application for superior performance. The calipers are precision-machined from a solid billet of aircraft-grade aluminum, forming a lightweight, one-piece forged construction that guarantees exceptional strength and resistance to corrosion. These calipers feature aluminum pistons, which offer superior heat resistance and reliable operation under demanding conditions. Additionally, DOT-compliant stainless steel braided brake lines are standard, providing a quicker pedal response and a firmer pedal feel by eliminating line expansion under pressure. This Supercomp kit comes equipped with SC5 Street Pads (NAOC Ceramic), which are optimized for street driving and occasional track use. These pads offer a significant reduction in brake dust (50% or more compared to race pads), minimize noise, and reduce rotor wear, with an optimal operating temperature range of 194°F - 1022°F. For rotor customization, you can choose between slotted or cross-drilled designs. Cross-drilled rotors are recommended for daily-driven vehicles due to their superior cooling, while slotted rotors are suggested for vehicles intended for more track use. Ksport Big Brake kits are built to order, and customers should anticipate a production and delivery lead time of 4-6 weeks. While this kit is designed for the 1990-1998 Nissan 300ZX, it's crucial to confirm exact fitment for your specific vehicle configuration. Fitment Industries will work with you to ensure compatibility, and if an issue arises due to an error on their part or an incorrect fitment recommendation from their sales team, they will facilitate a return with no restocking fees, provided the item remains in like-new condition.
