Fitment

Please Note: Differential settings can only be changed during disassembly/overhaul - not externally adjustable. Professional installation recommended.
  • 2004–2014 Subaru | WRX STI

Description

The Cusco Pro Adjust LSD is a high quality and highly adjustable differential. Although the Type MZ and Type RS can be changed to 1.5 or 2 way by switching the internals, the sensitivity and locking speed of the Pro Adjust LSD can be changed in very precise and in small increments using cam chips of varying degrees. This system will enable you to make changes at the track to truly fine tune the high speed handling of your race car. We recommend these LSDs for professionals only!

  • Rear differential - replaces the factory rear differential on the 2004-2014 WRX STI
  • Type-RS Pro-Adjust design with an initial set-up of 1-way 55/0 deg
  • Interchangeable 1, 1.5, and 2-way configurations via cam chips
  • Fine-tune sensitivity and locking speed at the track
  • Settings can only be changed during disassembly/overhaul - professional installation recommended
