Well my car just got to 90,000 miles and I am thinking of putting it back to N/A after being turbo for 6k miles. While I have all of the turbo things out, I am thinking of replacing my motor mounts just due to the mileage my car has. The mounts do not look broken but on shut off, the engine seems to shake more than my friends s2000 who has lower mileage.

Would you recommend upgrading to different mounts or oem? Should I also replace the transmission mount aswell?

 

i recently replaced my mounts with 75a innovative mounts and an 85a transmission mounts. the mounts initially vibrated but it seems to have calmed down. it seems that tranmission mount causes a lot of vibration, i have a lot of vibration and resonance between 1000-2000 rpm, but after that it's ok.

 

If you are looking for less shake, stay with OE. If you want your car to shake to pieces get some racing solid mounts. Why are you replacing something that isnt in need of replacement? Every engine/trans shakes slightly, thats why the mounts are made of urethane

 

Ive found that at 100k they might appear at a glance to be ok but they are cracked or seperated and needing to be replaced.

As mentioned above, OEM if you want a normal feel, aftermarket race version but it will have a bit more overall vibration
