Complete the System: ES4 Rear Forged 4-Piston Caliper

Don't neglect your rear brakes—balance your setup with the ES4 rear caliper. This forged 4-piston caliper is the essential companion to your front big brake kit. It’s engineered to restore proper brake bias, ensuring your car remains stable and predictable under hard braking, preventing the rear from becoming unsettled.

We designed the ES4 to be lightweight yet incredibly rigid, reducing unsprung mass without sacrificing strength. It’s built with the same high-performance components as our front calipers—including ventilated pistons and high-temperature seals—to deliver consistent, fade-free performance that you can rely on.

Frequently Asked Questions

How can I be 100% sure this rear kit fits my car?
The best way is to contact us directly. To guarantee a perfect fit, please provide your vehicle's year, make, model, and wheel specifications (size and offset). Sending photos of your current rear brake setup and your VIN can also speed up the confirmation process.
What's included in the complete ES4 rear brake kit?
Our complete rear axle kit is a bolt-on solution that includes everything you need for the upgrade:
  • 2 × ES4 Forged 4-Piston Calipers
  • 2 × Two-Piece Brake Rotors
  • 1 × Set of Performance Brake Pads
  • 2 × CNC-Machined Caliper Mounting Brackets
  • 2 × Stainless Steel Braided Brake Hoses
Why should I upgrade my rear brakes?
When you install a powerful front big brake kit, it shifts the car's brake bias forward. This can make the rear end feel light and unstable during heavy braking. Adding our ES4 rear kit restores the correct balance, ensuring stable, predictable, and ultimately safer performance.
