SuperPro 1990 Mazda Miata Base Rear Differential Mount Insert Bushing Kit

SuperPro 1990 Mazda Miata Base Rear Differential Mount Insert Bushing Kit This kit replaces the forward differential mount bushings, known as the pinion mount bushings. The OEM units are made of soft rubber and tend to break down quickly, especially under heavy use. Worn bushings allow increased movement of the rear differential under changing loads. This can initially be felt as slower and less responsive handling. As the OEM bushings wear out, it can lead to noise, vibration, and secondary movements under changing loads, particularly during acceleration and deceleration. SuperPro's differential mount upgrades maintain OEM levels of noise, vibration, and harshness isolation in the cabin, preserving the factory comfort levels. At the same time, performance is significantly improved with the differential more accurately located under a wider range of conditions. The service life is dramatically extended, with materials maintaining peak performance throughout their lifespan, unlike natural rubber which softens and degrades over time.This Part Fits: Year Make Model Submodel 1999 Mazda Miata 10th Anniversary 1990-1997,1999-2005 Mazda Miata Base 1993 Mazda Miata LE 2000-2005 Mazda Miata LS 1994-1997 Mazda Miata M Edition 2004-2005 Mazda Miata Mazdaspeed 1991,2000-2003 Mazda Miata SE 2003 Mazda Miata Shinsen 1997 Mazda Miata STO
