Approaching 80K, what bushings to replace?
Carmakers use rubber because rubber provides a more compliant ride and has less NVH than polyurethane, and thus results in fewer complaints from owners. But the whiteline bushings have a lower durometer (hardness) rating than other poly bushings, so should be fine for the street.

where are you getting this, please do not spread misinformative blanket statements like that. There have been numerous users on my350z who have used the whiteline polyurethane bushing in the front lower transverse link as well as rear subframe bushings. The only person that has run into issues with whiteline polyurethane bushings was a user who installed them in the rear knuckle and ended up with his spl camber arms damaged. This HOWEVER was not confirmed to be caused by the bushings and even IIRC kuah from SPL jumped in and said the damage was most likelly caused by strapping the car down to the dyno by the control arms. So take it for what it is, there has been NO substantial evidence to say that you are NOT SUPPOSED to use polyurethane bushings in the suspension. Granted there are points such as the inner compression arm bushing where a free pivoting bushing needs to be used and a polyurethane bushing will bind big time.
Certainly Nismo with decades of experience building and racing race cars they must know something no one else does and that's why they make hard rubber bushings instead of polyurethane.
They wouldn't make solid ones like SPL because they know a lot of people wouldn't spend the extra money or not mind the NVH (even though I have very little of over stock at this point.)

Just hit 80k last night...
Andrei, what's your current setup? I saw your thread about the SPL comp bushings, looks like you did LCAs as well. Anything else done in the front, or anything in the back?

I ordered Whiteline bushings for spring bucket(inner is seized) and rear shock mount.
what NVH we should worry about with our loud exhaust systems, low profile tires, stereos and stiff as hell springs? Can it get ANY worse than it already is ?

My bushings are gone, i'm at about 120k...my front lowers to be exact. My whiteline bushings came in about two days ago, throwing them on in a few days will report back on performance
G drives like new with the bushings dropped in, i thought i needed new shocks but that was not the case. Night and day difference, especially turning. Car seems a bit higher in the front as well with the whitelines
just the two front lower, had all of the fore mentioned issues here...cracking sound, rough steering, and so on....all the aftermath of 20" rims
How was the ride quality? Really bumpy/jittery or overall fairly smooth on road imperfections?
