From our differential building and racing experience, we are offering this awesome differential cover for your 135 and 335! BMW will tell you that the gear oil is a life-time fill, sadly that nonsense that helps them skirt costs. This frustration is compounded by the fact that the OE diff cover doesn't even have drain and fill plugs!

Under hard use, LSDs equipped diffs can run very hot, even the OS Giken diffs have been known to cook gear oil. Our finned cover is stronger and offers much better heat dissipation that these cars need when going to the track.

Each VAC Finned Diff Cover Features:
• Increase oil capacity by a whopping 50%
• Increase cooling capacity via heat-dissipating fins
• Machined from a single billet of 6061-T6 aluminum
• Drain and fill holes are machined for “AN” style o-ring plugs; easy conversion to a diff oil-cooler setup
• Integral vent for street cars; pre-machined provision for external catch-can setup for racecars
• Pre-machined provision for differential oil temperature sensor
• OE Quality 10.9 grade flanged hex head hardware provided
• Improved Strength over Cast Cover
• No adverse effects on ride quality or noise
• Excellent ground clearance (We have yet to hit the race-length cover on our lowered city daily-driven 135i!)
• Available in street length and race length
• As always, Made in the USA in house at VAC


A worthy upgrade for your E82, E87 E90, E92, E93 differential / LSD setup.

Tech Notes:
- Fits RWD and AWD XI models!
- Convertible Models (E93 and E88 cabrio) require slight modifications to OEM chassis bracing: 3 longer bolts are required, and only the Street Cover will clear this chassis

PLEASE NOTE : THESE PARTS ARE GENUINE BMW / BMW MOTORSPORT ITEMS, THEY ARE NOT THE CHEAPER AND INFERIOR FAR EAST MADE VERSIONS (THAT OFTEN BREAK) !! THE BMW MOTORSPORT (UNLESS WE ADVISE OTHERWISE) COME IN THE HARDENED FINISH

Need to alter the final drive gearing on your rear axle to suit new tuning modifications ? This is easiest acheived by swapping the internal gears within the rear differential housing to give either a higher or lower than factory final drive ratio .

A numerically higher ratio will give lower gearing, equating to increased acceleration but decreased potential top speed ....and vise versa.

MANY CARS CAN AFFORD TO LOSE SAY 10 - 25MPH TOP SPEED IN FAVOUR OF THE BETTER ACCELERATION AND OVERALLL "PULL" THAT LOWER GEARING WILL OFFER.

Made from hardened steel surpassing OEM specification.

We can offer almost any ratio for almost any diff, 188 and 210 cases, 14 and 12 mm bolt holes.

We can supply the gear sets either new or second hand at significant saving, all second hand parts have been inspected and x ray tested.

Please contact us for best prices and availability, here is typical price selection :

- E36 and E46 M3 3.91 or 4.10 gear set £830.00 (BMW MOTORSPORT)
- E92 M3 £890.00

When changing rear differential gear ratio sets it can often be difficult or impossible to remove the existing side bearings without damaging them, so in most cases it is simpler to purchase new bearings at the same time as the gear set.

Includes housings.

We offer these bearings for most BMW models, please contact us for details prices.
