Machined aluminum mounting point imbedded in tuned durometer urethane bushing. Harder durometer (90A).
Ideal for the 6 cylinder Mk5 R32, Audi A3, TT, TTRS.
HPA 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 accelleration.
Shifter engagement is faster and easier and stability is improved.
By carefully studying the dynamics of various durometers of urethane, and putting them through long term real world testing, we have chosen the best combinations of mateirals to achieve a comfortable yet firm result.
These mounts will solidfy the engine's connection to the chassis while still isolating its vibrations from the cabin.
HPA Core Interlock Performance Motor Mount for Mk5+Mk6
Looking for a more refined driving experience than that offered by other aftermarket Urethane Engine Mounts, HPA set out to develop a solution which would offer its 565HP twin turbo creations the crisp powertain engagement of a Nurburgring prepared R8, with the vibration free idle of a Veyron.
“The Key lies with the pendulum mount”
Recognizing the engineering that went into the OEM side mounts, it was easy to isolate the weak link. The lower mount is charged with managing the entire torque shift of the engine throughout braking and acceleration.
In the OEM design, we found the aluminum arm and stamped steel bracket to be strong enough to manage the forces applied to it, and although the rubber insert effectively dampens vibrations, it leaves a somewhat “sloppy” feel of engagement.
Focusing our engineering efforts on how to improve this component, the unique Core Interlock* design was born to balance the Mk5’s sensitive chassis harmonics while maintaining a comfortable feel of the engine at idle
Designed in house and installed on every HPA creation dating back to the RGT Jetta and Passat, HPA’s Core Interlock* motor mount works in a harmonic relationship with our proprietary durometer of urethane to effectively dampen the engine’s vibrations while efficiently controlling the energy transfer between the engine and the subframe under acceleration and braking.
The Urethane’s 100% mechanical integration with HPA’s vertebrae-like Core Interlock* creates an ultra efficient means to offset the torque of the engine against the thrust section of the mount.
Unlike the 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. The ride comfort is retained, but the shift response and chassis feel is vastly improved.
