Offering the longest time before rebuilds avalible due to our attention to deatail and excelent machine work we offer in house.<P> We highly recomend our Carbonetic differentials as they offer amazing life, smooth response, and excellent durability. Also, we are the master importer for Quaife BMW applications in North America. These diffs use gears so there are no clutch plates to wear out and are exceedingly smooth with no noise making them perfect for the race car or street car. <ul> Our Performance differentials feature:<br> <LI>All New OEM bearings, seals, crush rings, and gaskets <LI>Drastically improved acceleration by transmitting torque to the wheels <LI>The highest quality Ring and Pinion gears <LI>Option of other non-factory LSD units <LI>Excellent machine shop workmanship <LI>Race & street proven reliability<BR><BR><BR> Take advantage of our our expertise with BMWs.<BR> Many of our winning VAC Engine customers also run our VAC performance differentials!</UL> *Core required, if no core is available, we can supply a core*<BR> </P> <P> <LI>SKU: VAC-HPD-E46M <LI>LSD Type: Factory ///M variable LSD; Quaife Helical Torsen LSD; Carbonetic 1.5-Way LSD (80/40% Lock); Carbonetic 2-Way LSD (80/80% Lock)<LI>Gear Ratio: 3.15; 3.25; 3.46; 3.73; 3.91; 4.10; 4.45; 4.75; Reuse stock base M3 (3.64)<LI>Chassis Type: E46 (M3) </P> <P><B>Other products in the category <A HREF="http://www.nexternal.com/vacmotors/Category187" TITLE="Drivetrain">Drivetrain</A> / <A HREF="http://www.nexternal.com/vacmotors/Category191" TITLE="Differentials">Differentials</A>:</B> <BR clear=left><BR><LI><A HREF=http://www.nexternal.com/vacmotors/Product2028 TITLE="Carbonetic - Carbon Friction Limited Slip Differentials">Carbonetic - Carbon Friction Limited Slip Differentials</A> <BR clear=left><BR><LI><A HREF=http://www.nexternal.com/vacmotors/Product428 TITLE="E30 Rubber Differential Mount Bushing">E30 Rubber Differential Mount Bushing</A> <BR clear=left><BR><LI><A HREF=http://www.nexternal.com/vacmotors/Product1933 TITLE="Kaaz - Limited Slip Differentials (LSD)">Kaaz - Limited Slip Differentials (LSD)</A> <BR clear=left><BR><LI><A HREF=http://www.nexternal.com/vacmotors/Product2188 TITLE="Kaaz - Super-Q AE86 Limited Slip Differential (LSD)">Kaaz - Super-Q AE86 Limited Slip Differential (LSD)</A> <BR clear=left><BR><LI><A HREF=http://www.nexternal.com/vacmotors/Product356 TITLE="Quaife - A.T.B.
