From $270.00

Zerek Fabrication needs your knuckle cores!

No more Core Charge, you can either buy the service or the product.

After years of fighting to find cores to fulfill orders we no longer do core charges as lead times got out of hand, and cores got only harder and harder to find. We are doing our best to keep cores in stock to provide a quick turnaround time.

Zerek Fabrication Miata rear knuckles will allow you to bolt on any other factory Miata (NA/NB) rear brake caliper or any other aftermarket caliper. Get maximum angle with our Miata rear knuckle drift kit.
The purpose of bolting on another caliper is for safe drifting. When you pull the factory E-brake it either won't work or it is not responsive. By running a second caliper on each side you can now properly utilize a hydraulic e-brake. Purchase our Hydro Line Kit to safely plump your hydraulic e-brake to the second caliper and keep adequate pressure in your existing brake lines. This will make your new E-brake just as responsive as your foot pedal brake.
