Experience smoother, faster shifting and extended transmission life with the IAG Carbon Synchro Set. Specifically designed for the Late 2006–2007 Subaru STI and 2007–2009 Legacy GT Spec B, this carbon synchro upgrade is a must-have for performance-driven rebuilds or gear replacements. Whether you're racing, spirited driving, or daily commuting, the IAG Synchro Set improves durability, reduces wear, and helps eliminate gear grinding.

Features:

• Smoother, More Precise Shifting:
      – Dual carbon friction layers provide better bite for quicker gear engagement
      – Reduces the chance of gear grinding under aggressive shifting
• Longer Synchro & Gear Life:
      – Carbon friction surfaces reduce wear on synchro sleeves and gear teeth
      – Japanese brass body ensures durability under high load and heat

• Improved Reliability:
      – Precision machining ensures consistent performance and perfect fitment
      – Reduces internal friction and wear under spirited driving conditions

The factory synchros can wear out quickly under hard driving, leading to missed shifts, premature wear, and even internal transmission damage. Upgrading to IAG’s Carbon Synchro Set is the smart, reliable solution for Subaru 6-speed owners pushing performance or rebuilding their gearboxes.
