Our most powerful front brake upgrade This brake kit includes: 1. Enormous Aluminum 4 piston calipers (44.45mm pistons) 2. 12 inch CNC dimmpled, slotted, vented, Zink plated, and machine balanced rotors 3. DOT approved custom fabricated steel braided brake lines 4. Custom fabricated T6061 aluminum brackets 6. Wilwood brake pads 7. All needed hardware except for the hardware that holds the bracket to your car. We do not supply those bolts and we don’t know what thread they need to be! This is a complete kit Except for bracket Mounting Bolts. There are no other parts needed to complete the installation Except for bracket mounting bolts. Installing is very easy, and can be done in less than two hours. The lightweight Aluminum 4 piston calipers weight only 3.4 pounds and have 44.45mm diameter pistons. These calipers are available in many local auto parts stores, so replacing them is not a problem (part number Wilwood 6815). The vented slotted and dimpled rotors are professionally built with CNC machines, and zinc plated to prevent rusting. They can be bought at any local auto part store. The steel braided brake lines are custom made to fit this brake kit for easy installation. The Aluminum caliper brackets are made of the highest grade of aircraft quality aluminum on the market T6061. These brackets are very light and extremely strong. They will never rust or corrode. You have the choice of getting performance street brake pads or race only pads. I personally have this brake kit on my 620 and it made a big difference, my car now stops on the dime. This brake upgrade is also extremely lightweight; it will help reduce the amount of unstrung weight. This is important since it will allow your suspension to react to road conditions much faster than with heavy cast iron calipers. Your car will handle better and be more predictable. Over all it’s a great brake kit that will make your Z stop faster and better than you could ever imagine!
Note: Requires 15 or 16 inch wheels Minimum. This kit will fit stock 14 inch wheels if you use a 6mm thick wheel spacer and extended wheel studs. If you have a 1971 Datsun 521 pick up truck. There is no way the stock wheels will fit. Even with a spacer. Caliper sticks out 13mm or 1/2" past wheel mounting surface. see pics. You will have to machine down the hub diameter 1MM so you can slip the rotor over hubs.
Payment & Security

Kit bolts on great to a 521, you should purchase new bolts to mount to the hub though. Stock 14” 521 wheels do not fit this kit unless you run 2.5” wheel spacers.

Wilson’s front brake kit
Brake kit is very nice. But says in description may fit 14 inch wheels which did even come close to feeding 14 inch wheels even with multiple spacers. Then installed a 15 inch wheel still had clearance issues went with a Chevy rally wheel clearance issues went away. Do not recommend trying to use it with 14 inch wheels or even some 15 inch wheels but Chevy rallies fit perfect all all. It’s a great kit stops great

I freaking love LOVE this kit and the WILWOOD brakes are amazing! Stops on a dime, such a fabulous upgrade. Highly recommended them to anyone with an old Datsun. Kit is so easy the install. I did it in an old ass car port at my house.
