    With the R55, R56, R57 MINI having so much different than the previous model I am often asked what mod should be done first. Well here is the cheap and easy answer. The NM Torque Arm Bushing.
    [​IMG]


    This simple Polyurethane bushing simply slides into the factory lower engine mount. Why do we do this? Because the factory mount on the R56 MINI is a simple rubber bushing with 2 large air gaps on it. This bushing allows the engine to rock back and forth on accel and deceleration. The engine rocking contributes to a few different faults on the R56. With the engine rocking it creates a slight delay in acceleration. The engine rock also pulls on the shift cables making shifting hard, or even causing missed shifts. Some customers have reported the torque steer reduced from the axles not moving with the engine. If you have one please post your thoughts, or if you have questions.

    NM torque bushing

    I have the NM torque bushing installed on my 09 JCW, it greatly improves in shifting, clutch uptake, and less rubber band effect of the drive trainduring acceleration and deceleration.

    No noticeable increased NVH. It is a BIG BANG for the buck! Get IT...

    Way......
    How do the NM inserts compare (besides price) to the one piece BSH unit? I was leaning towards the street version of the BSH but was concerned about NVH with the small end not having some give since it's designed without a bushing?


    Duh.....
    Looks like the BSH unit for the R56 does have a bushing at the small end. Got confused with the BSH unit for the earlier MINI's that doesn't have the bushing.


    OK, still same question. How do the two compare performance wise?

    The NM bushing will be alot less NVH. Performance wise I think the NM performs great. It's not going to be as solid as the BSH mount, but that's the trade off you have to give to not have NVH.

    WOW....
    Clicking the keyboard early this morning eh Way?
    Thanks for the quick return.
    So NM alot less NVH than even the street version of the BSH? The track version must really be something else?

    I'll wait for a few more member responses and then you can expect an order from me.

    Oh, by the way, I think it's very clever the way you throw out open discussion on your MINI performance parts, getting non-bias feedback from the members.:Thumbsup:

    Honestly I've never driven an R56 with the Race BSH mount. I just know how hard the street version was.

    I'm not trying to be clever. I'm trying to get customers to put their opinions in writing so my other customers can learn more about a product and it will be "Real" info. I do always try to give honest advise, but some customers will always be weary of what I say because I am trying to sell something.

    yes it is early for me:frown5:

    What secures the insert? Tolerance fit? Or is it sandwiched when you install it?

    I'm just curious if there should be any concern of them falling out, especially with the torque arm being so low and prone to bottoming out on lowered cars.

    I've been meaning to get a set, but I've always been curious about this.

    Yes the sandwich fit holds it in place perfect.

    I have yet to see anyone bottom out a MINI at the torque arm. But Rally your car would def have the best chance :D

    So are these for R53's & R56's? I know Powerflex already made these for the R53, how are they different or better? And I belive the BSH mounts only have a bushing on the big end, they are solid on the small end.

    When I was under the MINI installing the under panels, I checked out the torque bracket. Basically two bolts holding it on. Looks like you remove them drop the two inserts in place and re-install. I'm not positive if both bolts need to be removed. Didn't look too complicated. I'm sure a lift would make it easier.

    If you go to the NM Engineering site, they have a download with instructions.:Thumbsup:

    I read someplace that you can just take out one bolt, rotate it, put the insert in and bolt it back up. Don't forget to torque it. You will notice a difference for sure. The small amount of vibration is not bad. I just pretend I have a big cam. :lol:

    Installed the NM Engine Torque Arm Insert I got from WMW. Real easy install following the instructions included with the kit. From the time I backed the MINI up on my ramp (made from 6"x6" wood posts cut with a slope on one end) to being done took all of 20 minutes. Everything went together with no issues. :D

    Nothing noticeable on the way home.

    But when I was on the Dragon last week I did hear a couple of time the MAP sensor / air box smacking my Upper strut bar which was a little disconcerting. I built my bar purposely close to the engine because I wanted the cross bar as straight as possible for rigidity, it actually fits in the small valley behind the sensor and the front of the air filter box.

    Before I added the inserts I could rock the engine on the mounts fairly easily and after the inserts were in I couldn't get the same rocking, so there is an improvement from that standpoint. I couldn't tell if there was an increase of NVH, I've got more than enough NVH with my run flat tires now thank you.
