I have a 98 ss with the m6. I just recently put the Energy suspension transmission mount and torque arm bushing in. This should be high on the list of first mods. What a difference it made on my car. Made it feel alot tighter. The only question I have is it vibrates at highway speeds. I saw all the stuff about removing the preload plate and grinding the bumps down and putting washers under the crossmember. I have already put 1000 miles on it and it still does it. Should I modify mine. I dont mind the extra noise, its just the vibration. Im going to the track tomorrow and want to know if it will hurt if I dont do it before the track..



thanks

 

ever hear of a smooth running race car? You have essentially stiffened up your tranny to car mount.. so why wouldnt it transfer more of the vibes now?

Its totally normal.. I used to run the ES bushings.. I like them but with my 2002 (i had a 1995 before) I want a plush ride for a while..

Maybe later on I will start with the mods.. I would also suggest that ya get an Airlift airbag and mount it in the right rear spring.. At the track, inflate to about 22psi.. preloads the right rear giving you a better launch.. for $35 its not a bad deal but you do need to go halfsies with someone as they sell them in pairs..

 

i was told to give it a while - it will smooth itself out. and no it shouldnt hurt you at the track.

 

I removed the preload plate and grinded the bumps down and didn't use any washers under the crossmember. no vibrations really. love it.

 

Mine is actually starting to get better.........Ill try if it doesnt go away........thanks

 

Mine shakes the change right out of my ash tray and i love it

 

It doesnt go away.. you just get used to it.. stop whining or go buy a caddy instead

 

mine went away a little bit but the vibration is with you from now on

 

Im not whining .........I just wasnt sure if it is normal for my whole console to shake like that.................

 

I have the ES transmission mount & torque arm bushings too. After installing the tranny mount, I had a wonderful vibration although it's not so noticeable anymore. I love it!
