The Z24 sport suspension came with "heavy-duty" bushings. Where as the regular models came with different bushings "soft-ride". Since there is no poly rear control arm and trailing arm bushings... 
My question is, can these bushings be interchangeable between the 2 different suspension types? If I have soft ride, can I simply buy the heavy duty bushings for Z24 model and have them fit the same?
Thanks ahead...
 
yes they are interchangeable. but RSM make a rear trailing arm bushing
 
see ya!
 
 
Yea, but I have problems w. High Rev, therefore I'm not going near their affiliates. 
Also, it costs $200 for a few bushings, where 1/2 of it you can get from prothane for $35. $165 dollars for rear bushings seems  little outrageous.
Thanks for the info.
 
^ nope i just called rsm and they said 80 bucks for just the rear
 
see ya!
 
 
Okay great! I think I'll just do that. Thanks for the effort in calling them.
 
Yea I just called them too. Have to wait 3 weeks for them to get urethane in. Oh well, it's worth waiting for.
