The RWD MM (Mid Motor Mount) doesn’t come with a damper plate as does the LM (Low Motor Mount). Who knows why not but the missing plate impacts handling quite noticably. If you swap out the MM for a LM mount you can use the stock LM damper as F1nutz has in his post. If you still wish to use the MM mount (or have no choice but to) then you can either add an aftermarket damper plate or make your own.
It’s easy to make your own using one of my favourite materials that are free: old credit/bank cards.
After cutting out the three pieces (top and bottom circle plates and the middle doughnut plate) file down the shock screw mount which is attached to the top of the motor mount in order to lower it a few millis.
Use a few 3mm DArt urethane washers to add some pressure to the centre plate (in lieu of springs) and tighten the screw till everything is snug. The tighter the screw the stiffer the movement.
