Wilwood 15-20 Toyota Land Cruiser J70 Series Front GN6R Big Brake Kit - GT Slotted Rotor

If you're looking to significantly improve the stopping power and heat management for your 2015-2020 Toyota Land Cruiser J70 Series, this Wilwood GN6R Big Brake Kit is a serious upgrade. This kit replaces your factory front brakes with larger, more capable components designed to handle the demands of heavier vehicles and more aggressive driving conditions. It’s built to give you more confidence when you need to slow down, especially under load or during extended braking events.

At the heart of this kit are the massive GT 72-vane slotted rotors, measuring 14.25 inches in diameter and 1.375 inches thick. The larger diameter provides more leverage for the calipers, while the substantial thickness helps dissipate heat more effectively. The GT slots are specifically designed to help clear out dust and gas that can build up between the pad and rotor surface, ensuring consistent contact and improved braking performance, particularly in demanding situations. The GN6R calipers are a six-piston design, offering a larger pad surface area and more even pressure distribution compared to smaller, stock calipers. This translates to better clamping force and more controlled braking. The calipers are constructed from forged aluminum for a strong yet lightweight housing.

This kit includes everything you need to convert your front brakes: the calipers, GT slotted rotors, caliper mounting brackets, stainless steel braided brake lines, and all necessary hardware. The stainless steel lines are a crucial part of the upgrade, as they resist expansion under pressure, providing a firmer pedal feel and more direct feedback from the braking system. While this is a comprehensive kit, it's important to ensure you have adequate clearance for the larger calipers and rotors within your existing wheels. Wilwood generally recommends a minimum wheel diameter of 17 inches for this type of kit, but checking specific wheel clearance is always advised before installation.
