s14 KA-T shakes at high speed when i let go of the throtle

[desertKAdrifter]

i have this problem where if im going over 70 and let go of the throttle in gear my car's rear section starts to shake. It started happening after i lifted my car on jacks to install my exhaust. i did notice that when i lifted my car the subframe bushing were pretty worned out and then when i dropped the car back to the ground the subframe bushing didnt seem to go in right. Does bad rear subframe bushing cause a problem like this or could it be something else.

that what it sounds like to me, does it do it when you turn, and almost feel like it pulsates?

not at all its fine any other time. its only when im at high speed and then try to slow down in gear. if i press down on the clutch it goes away,

ok, it might be close to being right but slightly off, ill talk to a friend of mine that works on 240s and see what he thinks

sub frame spacers are supper cheap and easy to install.. might be your diff bushing..
fr sport has both in stock and makes a big difference.. get the DIF ones
