Servo grommets necessary for brushless setups?

[Jesse M]

Are servo grommets necessary for brushless setups to dampen any vibration.
If so, are the brass bushing inserts necessary because I can only find circular grommets for my JR 9100 on Ebay, but they do not show/include the brass bushings?

Vibrations from/to the servo cant be stopped by grommets because when it bottoms out especially in offroad or a solid crash. Electronics will still feel it with a 1/2 inch of foam

I've never run grommets with any of mine, but I do use a servo clamp that holds the servo and prevents breaking the ears off the case. I'm of same mind as Drifting101 - grommets are not going to provide much in the way of dampening with the shock these things see in landings and tumbles.

Servos have come a long way since the 70s.... if you are having problems wearing out servos from suspected vibrations, you need to get past the $20 servo and get something in the $50-$100 range. I have had top servos last 10 years of racing in all sorts of cars.
