Bushing Questions

[Phantom Gett]

I've been all over the Internet, including some of NICO as well, and I have some questions...

I bought the Energy Suspension Master Kit for the S14 a while ago, and I've been slowly chipping away at it. It's tough, the front just got fibinished recently and I must say, it feels great! Much tighter and more responsive, but it's getting close to time to do the rears, and from what I've read so far a lot of people regret doing it to their dailys. My 96 is Daily driven and I was hoping to replace all my bushings but not need a stadium cushion to avoid a crushed pelvis everytime I drive to work...

Aside from the rear control arm bushings, I was looking at the ES Subframe and Diff kit, which was the part that worried me since I've been seeing people talk about how it makes it un-drivable on a daily basis, which would prompt Nismo replacements but since they've been discontinued, I don't know what to do, so if anyone has any opinions on the Poly ES kit or the Nismo one, please chime in, I'd like to be able to form my own opinion but a little secondhand experience never hurt, so please, chime in!

I drive mainly upstate New York roads.

I have an s13 with the full es polly kit. I also have installed s14 es polly subframe bushings. They dont make the ride harsh at all. The car just feels tighter and more controled. The only thing I have to complain about is some noise. after installing the subframe bushings Ive had alot of whining noise from my diff., but s13 diffs are also directly bolted to the subrframe without any bushings at all. I would say because you have bushings on both your diff and subframe that going full poly more than likley only give you a little to no excess noise.
