I already sent an inquiry to bimmerdiffs last month. 2-clutch clutch refresh kit, $240.99 Jonathan Thayer Oct 16 (3 days ago) The 318Ti uses a 168mm differential. Typically they take the 23-tooth clutches but sometimes they take 21-tooth clutches. There is no way to know for sure without taking it apart. Because of the size of the differential we only offer the 2-Clutch Stock Refresh Kit which can be found at the following link: http://www.bimmerdiffs.com/collectio...ck-refresh-kit Please let us know if you have any other questions! __________________ 1996 Ti 280k miles and still going.... 1993 964 - holding on to this one 2001 Burban, 240k miles 2018 Suburban Z71 |
