This package of OEM E82 E90 E92 diff mounts replaces the stock rubber diff bushings. On a tuned 335i you may have noticed more driveline shudder or problems hooking up during hard launches. What happens is the stock rubber bushings are under constant flex as engine torque is transmitted through the differential. Under normal driving with a stock car the bushings are rarely stressed. But factor in significant additional torque from a tuned N54/N55 and the stock rubber will quickly show its weaknesses. You may have even broken a diff bolt or two as the heavy differential shifts around. Even non-turbo E82 and E9X models may benefit from fresh bushings.
This is a set of stock rubber bushings, made by OEM supplier Lemforder. They are the same as the Genuine BMW E9X diff mount bushings, but without the more expensive branding. If you're turned off by potential side effects of urethane or Delrin then the OEM diff mounts are your best option. The OEM mounts fit and perform just like the originals so there is no second guessing their quality. If you're looking for an upgrade we offer E9X solid Delrin and aluminum diff mounts that work well, even in street applications.
E9X Diff Mount Set includes:

This is a complete differential to change the gearing of a manual transmission E90/E92 325i, 328i, or 330i (not for xi models) to a 3.64 ratio final drive. The standard gearing on the manual transmission cars is 3.15 or 3.23, making this E90 diff significantly shorter. This diff is from a 330i automatic where the gear ratio has to be shorter to make up for the transmission gearing differences and extra weight. This will dramatically improve acceleration on any 325i, 328i or 330i INSTANTLY! If you are looking for better off-the-line or rolling acceleration, and are willing to sacrifice a little top-speed (some of us don't get up to 150mph), this is one of the best ways to achieve it with almost no downside. There are few things that can improve your 0-to-60 and 0-to-100 times as much as shorter gearing, and this differential is clearly a best "bang-for-buck" solution for dramatically better acceleration. Since this is an Original BMW part it carries the same BMW two year warranty as any other new part. So there's no need to take a chance on a used part from a private seller. (former BMW part number 33107519944)
Changing gear ratio changes the RPM range for any given speed. Use the chart below for examples of speed vs RPM changes for the 3.64 diff.

Why 5th? Because 6th does not have the mechanical advantage to get past wind resistance at these speeds - it is more of a cruise/overdrive gear. Using 5th for comparison purposes is much more relevant than having to take into account wind direction, resistance, grade, elevation, tire sizing, etc. These numbers are for comparisons among gear ratios only, not to determine what your E90 will top out at.2006-2011 325i or 328i, 6-speed manual, stock 3.23 gears, 255/35-18" rear tires
