Hi Everyone, Have few questions and would like to hear from all you guys.
Since my car is a 92 Turbo and the rear suspension should be time to change( I already change the AGX suspension) I am thinking to chenge all rear Trailing Arm and Lateral Link. I know the 92 and 93 are different and I think I will go for all GC rear arm and link since its more easier to find and order.
But here still some questions needs to know about before this project:
Will it be easy for DIY at my garage?
How much will be cost from Dealer for all new arm and links? Will it comes with all the bushing?
I am also thinking to take out all my old one and put in some polyurethane bushing will it be easy or hard to do?
Or should I go look for some uesd STi link and arm kit is better?
Whats the adventage or disadventage if I go change it ?

Thanks for all the reply and hope those question could also help others.

it would probably be better just to keep your stock links and get some poly bushings. the links shouldnt go bad unless you crash the car or are rallying it a lot. from what I hear the poly bushings are pretty hard to press in, very tight. I was able to do my shifter bushing with a clamp and some boards, but be warned. if you have a good vice that might help.
bushings from the dealer arent cheap. I havent priced them exactly, but poly is cheaper from what I have heard.
