Description
The CorkSport Race Rear Motor Mount offers superior support to the engine and adding direct feedback for superior performance. Designed for the CorkSport TC America Race Car, the RMM eliminates the slop that the soft OEM rubber material provides eliminating excessive engine movement. The improved support increases throttle response, shift feel, and vehicle feedback for optimal race performance. Although the RMM is an aggressive increase in NVH, the provided improvements to vehicle makes this an important modification for those looking to turn their Mazda 3 into a race car.
DUE TO THE INCREASE IN NVH, THE REAR MOTOR MOUNT IS RECOMMENDED FOR RACE CONDITIONS ONLY. WE DO NOT RECOMMEND THIS PRODUCT FOR DAILY DRIVING CONDITIONS.
The CorkSport Advantage
Race-Inspired
Designed for the TC America Race Car, the Rear Motor Mount offers an aggressive improvement for the ultimate driver feedback for your Mazda 3. The power transmitted from the engine reduces the lazy feel of the OEM motor mount, offering an increase in responsiveness to the chassis. This improvement offers your Mazda 3 an increase in racing performance when every second matters.
Materials & Manufacturing:
The Race Rear Motor Mount is the perfect OEM replacement for race enthusiasts looking to improve their Mazda 3 for the track. Manufactured with A356 -T6 Aluminum and mounted with 95A polyurethane bushings, the RMM provides a durable and long-lasting mount. Designed to fit like OEM, the mount offers an easy-to-install mod for your Mazda 3.
Design Focused:
The Rear Motor Mount provides a sleek design that still offers the function of the RMM. We reduced the overall size and material to simplify the design and reduce material. The RMM also provides fitment points identical to the OEM placement making it a perfect replacement. Finally, we used A356-T6 aluminum that is precision machined to accept the 90A polyurethane bushings and branded with CorkSport logo. This provides a well fit RMM that removes unwanted movement from the engine!
Performance Polyurethane:
The Choice of 90A durometer poly bushings was to reduce the movement of the engine. This was an aggressive improvement to provide the most feedback and responsiveness from the engine to the chassis. The bushings increase the NVH significantly but provide the car with the responsiveness needed for competitive racing. We do not recommend these for daily because of the increase in vibrations.
If you are looking for a moderate increase in responsiveness for your daily Mazda 3 then consider the street rear motor mount.
Steel Poly Sleeves:
The CS RMM bushing sleeves are precision machined out of steel to provide a robust and durable part that is then zinc coated to provide protection against corrosion.
Stainless Hardware:
The RMM replaces the OEM hardware with M14 stainless steel bolt, washers, and nylock nut. The hardware works perfectly with OEM fitment and offers corression-resistance under the elements. Due to increased vibration, the improvement in the material helps endure the stress of performance racing.
Weight Savings:
The CS Race Rear Motor mount saves 2.5 pounds of weight in your Mazda 3. The reduction from ~4.70* lbs to ~2.20 lbs, although minor, provides critical weight savings when every second and pound matters.
*OEM Turbo model RMM weight.
