Does anyone have any experience installing these bits? I try to bust the trailing arm lose today and no luck.. i tried to bust the rear lateral link lose today.. no luck.. stuck like chuck..need help

 

those bolts are hard. keep trying.
Use a metal pipe to extend the wrench, it"ll get it loose

 

Danny get an impact gun or a long pipe and breaker bar. Too bad you dont live in SD, as I have all of those.

 

how much does the STi, lateral links, trailing arms and stuff help? does it make a world of difference? just curious. they look sweet tho

 

Does it make a difference? Yes. But you better have your other suspension bits up to snuff. Think of them as icing on the cake. By themselves they are hardly noticible at all. But combined with a complete package, they are quite good and will help at making the rear end a little more predictable at the limit.
