I have a cobb rmm and i want to upgrade the passenger side mount. Its easy as hell to get to. My question is should i do the driver side too? i found people reviewing the passenger side only but no one said anything negative. When i had my rsx i only upgraded the passenger side with a 90a somthing urethene mount(clostest to solid i can get without being solid) and it was tourqe steer to the right out the ass when it hits vtec. Id tq steer into the other lane if i had one hand on the wheel ( i had to have one hand because my rsx would pop out of second so id have to hold it their hahaha). So my question is, is that going to happen with the st? or what should i do?

The drivers side is hardcore. I was getting wrc sounding gear noises reverberating off of the a pillar. If you do the passenger side I think you'll be really happy. I got the lowest durometer and there is very little deflection. Shifts are awesome and vibs are very minimal after it's broken in. It's responsible for motor roll reduction and does it well. I Autocross and with an lsd and hard launches on sticky tires just the lower and passenger side mount is needed I think. I switch to stock in the winter though.

I don't know if it's best to get both to "balance it out". drivers side moves a lot less because of the factory design. The aftermarket design applifies the noise and vib wildly on the drivers side. Drivers side motor mounts aftermarket wise are unnessary imho. In this car. Esp if you already have the lower done.
