Part sprSPF2875K. Stiffer engine, transmission and differential mounts reduce drivetrain movement for sharper throttle and shift response.\u003c\/p\u003e\u003cp\u003eThis kit replaces the forward differential mount bushings - known as the pinion mount bushings. The OEM units are soft rubber and break down fairly quickly with that wear accelerated the harder they are used. The worn bushings allow more movement of the rear differential under changing loads. This can initially be felt behind the wheel as slower and sloppier responsiveness, and as the OEM bushings near the end of their life or fair it can be accompanied by noise, vibration and secondary movements under changing loads - especially as you get on the gas and come back off of it. SuperPro's differential mount upgrades maintain OEM levels of noise, vibrations and harshness isolation in the cabin so your car maintains the new factory levels of comfort. At the same time performance is significantly improved with the differential more accurately located under a wider range of conditions and the service life dramatically improved with our materials maintaining peak performance throughout their life rather than slowly softening and degrading like natural rubber.\u003c\/p\u003e\u003ch3\u003eProduct details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart type:\u003c\/strong\u003e Engine \u0026amp; Transmission Mounts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e SuperPro\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation Difficulty:\u003c\/strong\u003e Difficult\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation Time (hrs):\u003c\/strong\u003e 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKit Contents:\u003c\/strong\u003e 4 Bushings\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Alignment Required:\u003c\/strong\u003e Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSuperPro part number:\u003c\/strong\u003e sprSPF2875K\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eVehicle:\u003c\/strong\u003e Mazda Miata MX-5 (NA), Mazda Miata MX-5 (NB)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eYears and trims on file:\u003c\/strong\u003e 1999 Mazda Miata 10th Anniversary; 1990-1993 Mazda Miata Base; 1994-1997 Mazda Miata Base; 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 Mazda Miata SE; 2000-2003 Mazda Miata SE; 2003 Mazda Miata Shinsen; 1997 Mazda Miata STO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication listing:\u003c\/strong\u003e SuperPro 1990 Mazda Miata Base Rear Differential Mount Insert Bushing Kit\u003c\/li\u003e\n\u003cli\u003eCheck the vehicle, model years, engine and trim above against your car before ordering.
