Finish the Rear Cradle:

PHR Subframe Reinforcement Braces for MKIV Supra

Overview

If you’re already under the car refreshing bushings, detailing, or tidying hardware, PHR Subframe Reinforcement Braces are a simple, high-impact way to make the MKIV Supra’s rear underbody look finished and intentional. The braces visually tie the rear cradle together for a clean, symmetrical presentation on a lift or at a show. As a bonus, they provide a modest reduction in subframe flex, lending a slightly more composed feel under acceleration and quick transitions.

Highlights

  • Aesthetic-first design: completes the look of the rear subframe; great “before/after” payoff.
  • Modest rigidity benefit: small reduction in subframe flex—noticeable mainly on hard launches or sticky tire setups.
  • Bolt-on & reversible: no cutting or welding; uses factory mounting points.
  • Two factory-correct fitments: choose based on model year (details below).
  • Titanium hardware upgrade available: elevates the finish with premium hardware.

Fitment Variants

  • 1993–1996 (Early MKIV)
  • 1997–1998 (Late MKIV)

Choose the variant that matches the vehicle’s model year. Both versions are designed specifically for JZA80 geometry and factory subframes.

Hardware Options

  • Standard hardware (included): quality fasteners for a clean, OEM-like install.
  • Titanium hardware (upgrade): lighter, corrosion-resistant, and visually premium—ideal for show builds or ceramic-coated underbodies.

What You’ll Notice

  • Visually cohesive underbody: braces “fill the negative space” and make the cradle look intentional and symmetrical.
  • Slightly more settled rear feel: a small improvement in subframe composure; performance effects are secondary to the aesthetic upgrade.

Installation Overview (Shop-Friendly)

  1. Lift the vehicle and support safely.
  2. Identify mounting points on the rear subframe (factory locations).
  3. Mock up the braces to confirm orientation and variant fitment.
  4. Install fasteners (use included hardware or titanium upgrade).
  5. Torque to spec.
  6. Final check: verify clearance with suspension movement and exhaust.

Typical install time is short and straightforward for any competent shop.

No. This is a bolt-on, reversible installation.

Which variant do I need?

Match the car’s model year: ’93–’96 or ’97–’98.
