Description

More connection. More control. Less drivetrain flex.

Your rear differential is mounted using soft factory rubber that flexes and twists under load. That movement absorbs energy, dulls feedback, and reduces how directly power is transferred to the wheels. The OVERTAKE Subaru WRX and STI Rear Differential Bushing Inserts solve this by reinforcing the factory mounts with performance-rated 80A durometer urethane, significantly reducing unwanted movement.

This is a small upgrade that delivers a noticeable improvement in drivetrain response and overall vehicle feel from the very first drive.

What You Will Feel

  • Crisper throttle response with more direct power delivery
  • Improved rear-end stability during cornering
  • Sharper and more precise gear changes
  • Immediate improvement in drivetrain feedback

Why It Works

The rear differential is a critical part of Subaru’s AWD system, but the factory rubber mounts are designed primarily for comfort. Under acceleration and cornering, they allow the differential to shift, wasting energy and reducing consistency. OVERTAKE bushing inserts slip directly over the OEM rubber mounts and are secured by spacers that lock everything together into a unified assembly.

The result is dramatically reduced deflection under load, improved durability, and more consistent power delivery. The urethane material resists heat, oil, and environmental degradation, ensuring long-term performance. While a slight increase in NVH is possible, most enthusiasts welcome the added drivetrain feedback as a worthwhile trade-off.
