i heard that my import could be running hard top mounts? which is why i am getting a knocking noise from the rear, not just over bumps but normal driving...is their any one who does a softened top mount? if not will get in touch with breakers and see about getting sum sti legs and springs....but im quite fond of the cusco and the way it makes the car handle but the knocking is fookin annoying....any ideas did the later models have soft mounts? will they fit mine?

 

You could just fit some standard STI rear top mounts and keep the Cusco struts. If you are certain it is the top mount making the noise.

 

if they are coilovers there will be slight knocking . ive got it on my car . try taking the top nut off .and putting spacers/ washers in . mine quietened down after i done this
