Introducing the Perrin Rear Motor Mount Insert (RMM) for the Civic Type R. The factory Type R Mount comes with slightly different bushings to the rest of the Civic lineup, and this insert is designed to fit it specifically

The Perrin RMM Insert controls the movement of the drive-train both on and off throttle giving you a more positive feel, and less wheel hop when launching the car from a stop.


After testing various setups personally, Unity Performance will offer both the Whiteline RMM Insert, and Perrin RMM Insert. Here's why:

- Whiteline is 1x 94a polyurethane bushing that fits all Civic trims. It's a great OEM+ upgrade for the enthusiast looking for less slop in the shifter, and less engine movement. Gains are noticeable, but you really don't feel any added vibration except for lightly in Reverse. 

- Perrin is 2x 70a polyurethane bushings that are softer than the 90a Whiteline, however having two of them makes it a more rigid setup, becoming an OEM++ upgrade. The benefit is less slop, but there is additional NVH. However, it is still friendly for daily-use, and to haul passengers around but you will know there is a a noticeable shake in 1st when setting off, and in Reverse. While driving there is slightly noticeable added NVH, but not intrusive.

Easy and cheap mod for any fk8

Humza recommended this RMM as I was getting bad gear grinds downshifting from 3rd to 2nd gear with high rpm and this thing helped a lot. Very easy install and is not too harsh while driving day to day. It is a noticeable difference with A/C on but not terrible. Haven’t had the heat grinds on hot or cold days under daily driving or track use since the install! Would highly recommend as one of the first mods as it’s easy and cheap with a huge performance change to the feel of the car
