In Response to letter #40266 The Club Spec Advisory Committee is seeking feedback on the following change to Engine and Drivetrain which would take effect 1/1/2027: M: Mazda Motorsports Torsen limited slip differential Part# 0000-02-5564 may be utilized. 
The CSAC does not anticipate this to cause a competitive advantage over OE units but will provide competitors with a long-term cost-effective option for potentially worn differentials.
