if your lowered, its better than stock, as its stronger and doesnt resist tearing....
if your at stock height, oem is fine if its new, problem is that they don't sell just the oem bushing (that im aware of, its complete arm with bushing) SO, ESuspension or whiteline is your only option. I would go whiteline.

I was actually thinking a bushing with a thin, very stiff urethane core layer, then softer urethane on the outer surface would resist tearing really well. This would also have bonded in metal sleeve like oem, except at an angle to compensate for the lowered suspension.

in the end its give or take, u have to pick a bushing that works for you, ie, it be scca rules, cost, etc....
once you lower the car, the amount of pull, angle is constantly tearing the oem bushing...hell the car just parked is tearing the oem bushing...
the oem bushing design is great - AGAIN "at stock height" , ie, parallel...
in the end, everyone out there replacing bushings just needs to choose the best option for them...
I run the SPL compression bushing....I have WANTED to purchase another one to machine the cone like L-fab did, or have new steel stepped tapered cones made.....WHY, just cause, do i need it?? NO.....my cars a pure track car and a little knock or noise is the least of my worries..

All I can say is WOW. What a difference. Where my car used to bounce a little, it's now firm. Turn in is much better (might be the sway) the ride is better, steering feel is better. I know I was going from torn bushings to energy's but WOW! I'm officially a fan. My Z feels better than it did new now and I couldn't be happier.
This thread was very helpful for me to determine what I wanted for the purposes and money. Thanks!

My concern from a stress concentration stand point is the machined STEP with out any radius in it. like i mentioned in post 39, i would monitor the modified cones for cracks. especially at that point.
STEP shown here:
I wouldn't put it to using any software or load calculating analysis as the time invested would be moot on such a small market item......I would just lean toward monitor and inspection...like you said, having an original set that came with the original purchased spl set can easily be put back on if later wear and tear shows cracks or anything coming from the modified ones.
my raising this question isn't to say this will definitely happen, but from a engineering/manufacturing stand point (I have years of experience in this) that stepped edge is a red flag enough for me to say "hey guys just inspect this area just in case"
AND if a track 350z that see daily driving and road racing for a year develops a minor crack, pff at that point, for the price, just replace the part.... thing is the people that want to daily drive and no noise will want the "install it and forget it mentality"....
machining a radius at that step will help...
not sure if SPL has any calculations to help or guide u on this, maybe hes already evaluated it and is why hes cool with getting you spares to begin with??

I don't understand why some folks are only going for the front sets if only purchasing Energy-Suspension. Should really go for the entire ES Front/Rear/Diff/& Steering Bushings Kits in one shot since its such a good offer in price compared to Whiteline...

Been reading through these suspension bushing threads, and am curious what experiences you guys have had after picking your bushings. I’m sure a lot of us would like to here a longer term review of these options.
-did the SPL compression bearing hold up on the street and did it cause a noticeable increase in NVH?
- did the Whitelines break in to become looser than expected? If so, did this break in land on a better than new OEM firmness
- any opinions on Nismo bushings
