Ksport BKMZ180-621SO Big Brake Kit Floating Rotor Slotted Piston Caliper Options - 4/6/8

The Ksport BKMZ180-621SO Big Brake Kit delivers a significant upgrade in stopping power over stock braking systems. Engineered with advanced brake technology, this kit is designed to dramatically reduce brake fade while continuously cooling and refreshing the brake pad surface during repeated braking events — making it suitable for both spirited street driving and track applications.

Caliper Construction:

• Lightweight one-piece caliper CNC machined from aircraft-grade billet aluminum — no casting or welding
• Differential bore configuration for optimized pad pressure distribution
• Each caliper weighs just over 5 lbs, saving significant unsprung weight versus OEM
• Machined-in protection grooves for bridge tube durability
• Aluminum pistons with high-temperature seals for superior heat resistance
• Stainless-steel brake pad wear plates standard on every caliper
• Opposed piston design improves pad wear evenness and caliper rigidity over OEM
• Available in 4, 6, or 8 piston configurations

Floating Rotor Design:

• Two-piece disc assembly reduces both rotating and unsprung weight
• Floating outer disc section shifts slightly as needed for better self-centering in the caliper, reducing brake drag
• Floating design prevents thermal warping and braking surface cupping under extreme heat
• Unique slot pattern expels gas and pad debris faster than conventional designs while minimizing brake noise
• Every rotor is heat treated and balanced prior to shipment for consistent, reliable performance
• Slotted rotors recommended for track and performance use

Brake Lines & Hardware:

• D.O.T.-compliant stainless-steel braided brake lines included as standard
• Stainless lines resist expansion under pressure for firmer pedal feel and quicker response versus OEM rubber lines
• Bolt-on installation with minimal tools required in most applications
• OEM ABS systems remain fully functional

Customization Options:

• Choice of Cross Drilled or Slotted rotor style
• Caliper color options include standard painted finishes (Orange, Red, Black, Yellow) as well as premium anodized and polished upgrades
• Optional Titanium or Twin Color Anodized center bell and hardware upgrades available

Cross drilled rotors are recommended for daily-driven vehicles as they tend to run cooler, while slotted rotors are the preferred choice for vehicles that see frequent track use. All Ksport Big Brake Kits are backed by a 12-month manufacturer's warranty covering defects in materials and workmanship. Note: Ksport Big Brake Kits are built to order.
