    Super Sale! 335i,135i Quaife Equipped Performance Built Differential - Ends 3/12/12!

    Since the group buy was a bit confusing, I went to the boss man and convinced him that I should simply offer the 10+ pc group buy rate as a limited sale. So, we changed this thread to a Super Sale and you all win!

    VAC Performance Built Differential with Quaife - A.T.B. LSD

    Sale Ends: 3/12/12 4:00AM EST (absolute last day, no exceptions)

    Welded core - $2,278 (insane $300 savings!!)

    Bolted core - $2,049 (awesome $200 savings!)

    Learn what fits your car and place an order here

    Note: Your car has either a welded or bolted differential. The link ALL product and application information can be found in the link above so you can choose the proper unit.




    Click here to see how we build these differentials in house.


    VAC Tips:
    -We have run a Quaife ATB HARD in our daily driven and often tracked 135i with absolute success.
    -We have sold a ton of these to other 135i and 335i owners with absolutely NO problems.
    -The ATB is the most popular unit that we install here at the shop on E8x and E9x platforms.
    -Additionally we have installed dozens of Quaife units in platforms other than E8x/E9x and they always perform flawlessly.

    Why do you want a Quaife LSD?
    Improved acceleration, traction and stability. Rather than using clutch plates as a method of operation, the Quaife ATB uses sets of floating helical cut gear pinions that run in pockets and mesh during normal driving. Should one of the driven wheels start to spin however, the helical gears start to generate a torque bias thanks to the axial and radial thrust of the helical gear pinions in their pockets. The result is a progressive transfer of torque away from the spinning side of the axle to the driven wheel, which is now capable of transmitting a greater proportion of torque. Unlike a plate style LSD the Quaife unit delivers performance without the need for strip downs and rebuilds. There are no plates or gears to wear or break and the ATB units retain standard vehicle lubrication.


    • All QUAIFE differentials come with a life time warranty.
    • Maximizes traction and minimizes wheel spin
    • Proven in drag and circuit racing, rallying and road use
    • Maintenance free design and retains standard axle lubrication
    • Produced from British Steel billets throughout
    • CAD designed and CNC machined then inspected to ISO 9001 standards
    • Used by Ford, GM and Daimler-Chrysler as original equipment



    Why VAC?
    VAC Performance Rear Differentials are built to last with the highest quality components, procedures, and technical expertise in the industry. We have been building BMW differentials since the 1980s - 2002, E46, E92, street, race - we have done it. We have been building various differentials for the last 40 years, so you can rest assured that the job will be done right the first time. Our BMW differentials are run in countless race series and by hundreds of street customers because our quality and options are unmatched. All is performed in our complete machine shop which ensures top qualify control. We do not have to worry about outsourcing it to a vendor who may or may not do the job properly. There will be no back log. We are proud of our process and we invite anyone to stop by the shop for a tour.

    Refunds
    -There are NO frivolous refunds on Super Sale orders
    -Only replacement of defective, or mis-shipped products are available
    -Members cannot change ratios after product is ordered

    Cores
    We have a number of 3.08 cores already in house, so there will be no problems kicking this off properly.

    If I hop on this group buy, will I be able to swing by in the October-November timeframe to get this installed? I won't be back in the states until then.

    Yea, that's cool man. We can either hold the built unit for you or we can ship it to any address you want. You will obviously have to pay for the core up front, but we will give you the full credit back when we take your stock unit out Click here to enlarge

    Cool. Trust me there are few mods better than a proper diff.

    I concur. Years back they sent us some stuff for a race prepared 02, and the price they asked for shipping to Iran was low compared to others.

    EDIT: it was shipped to UAE then we got it here in Iran iirc.

    If within driving distance why not just go there? Makes the most sense.
