    Thread: HPA Motorsports Core Interlock "Dog Bone" Motor Mount

    1. 07-28-2011 05:12 PM #1
      HPA Core Interlock Performance Motor Mounts are designed for comfort without compromise.


      Our upgraded mounts reduce motor flex to improve torque transfer to the drivetrain, and prevent excessive movement under hard acceleration. Shifter engagement is faster and easier and stability is improved. These mounts will solidify the engine's connection to the chassis while still isolating its vibrations from the cabin.


      The unique Core Interlock design was born to balance sensitive chassis harmonics while maintaining a comfortable feel of the engine at idle.

      Unlike other urethane inserts which merely reinforce the OEM rubber mount; this is a completely re-engineered one stop solution that will control the engine’s motion without the need to install aftermarket side mounts.

      HVW-904-85 Pendulum ("Dog Bone") Mount Applications

      Mk5 VW Golf/Jetta/GTI, Audi A3 2.0, Audi TT/TTS 2.0


      The HPA Core Interlock Motor Mount is available in four different durometers for the Mk5 and Mk6 platforms. They are physically interchangeable allowing you to fine tune the comfort vs. performance level to suit your driving style. Each durometer offers a distinct driving characteristic and is recommended for the following applications:

      • HVW-904-75 softest durometer, ideal for Mk5/Mk6 TDI daily driver
      • HVW-904-80 soft durometer, ideal for Mk6 Golf/Jetta/GTI daily driver
      • HVW-904-85 medium durometer, ideal for the 4 cyl. Mk5, Golf R, and 4 cyl. Audi A3/TT/TTS
      • HVW-904-90 harder durometer, ideal for the 6 cyl. Mk5 R32, Audi A3, TT, TTRS

      The reviews are in:

      I was super happy with the HPA Interlock from day one. Much quicker shifts, not really any noticable vibes in car, super easy to install took under hour from start to finish.

      No insane vibrations or buzzing. It’s quite comfortable.

      Just for sake of putting it out there, my vibrations have reduced since it was first installed.

      The mod is worth does this thing help smooth out the power delivery in the first few shifts from a stop...feels much better and seems like it comes off the line quicker and more purposeful.

      Definitely a noticeable improvement. Was much more noticeable when I switched to M mode, smoother shifts and a more planted feel, the herky jerky unsafe-feeling downshifts have been pretty much thwarted. Can't wait to flog it in some twisties! It is so choice. If you have the means, I highly recommend picking one up.

      I originally had a soft insert that I just didn't like, especially when cold! I do lots of highway driving and just don't like any NVH!
      Although this (HPA) puck is harder to install than a simple insert I think it is well worth it!
      ...(And I'm picky!)
