GT86 Rear BBK Upgrade: Full Bite with R1 Concepts

Completing the Performance Package on This 2018 Toyota GT86

Rex from the R1 Concepts Crew is back in the shop, and this time it’s all about finishing the job right. Our 2018 Toyota GT86 was already equipped with an R1 Concepts front big brake kit (BBK), one of the most popular upgrades for track-ready GT86 builds. The customer loved the improved stopping power so much, they returned to upgrade the rear with an R1 Rear Big Brake Kit for maximum control and visual impact.

When the front brakes bring that much bite, you’ll want the rear to match.

Why a Rear Big Brake Kit Matters

While the front brakes handle most of the stopping, a rear BBK for your GT86 improves balance, heat distribution, and braking consistency, especially when you’re pushing the car hard on backroads or at the track.

A rear BBK:

  • Reduces brake fade
  • Enhances stability during hard braking
  • Matches the aggressive aesthetic of the front setup

If you’re running a Toyota GT86, Subaru BRZ, or Scion FR-S, this is a game-changing upgrade.

What’s on This GT86 Build?

Here’s what this complete setup includes:

Pro Tip: When you upgrade both front and rear brakes, braking force is better distributed, reducing wear and improving handling during quick stops or late braking zones.
