Being the suspension junky I am I had to find a rear bushing. I know that the ES A33 bushings are to big. I also know how the P11, B14, and B15 have a similar rear beam to the A32. So, I got a spare A32 beam from a friend, just for testing these. As luck would have it they fit perfect. Its a popular item on G20.net, B15sentra.net, and SR20forums.com, I got them from octotat (on any of those forums) for about $66 shipped. They should go well with my full ES setup up front.
Original bushing removed (torch+knife):
Superpro installed!!!!
G20.net, B15sentra.net, and SR20forums.com also have more info with installs and reviews. I have not installed them on my car yet, probably wont until spring.
While very high on the cool factor, I wonder if that design is robust enough for an A32. All polyurethane is not created equal and the bushing is usually specific by design to a vehicle. The bushing looks robust enough but until someone installs and runs them in an A32 for 6month to a year, I'll wait. Good information and thanks for sharing JSutter. -Slopster

Anything that tightens up your suspension is good!
Super Pro is a polyurethane elastomer base material, and is a class of "Thermosetting" synthetic polymer that involves the reaction of various types of isocyanate resin with curing agents, to give an extremely durable material with the best features of rubber and plastic.
Super Pro is unique, it is the only polyurethane product range fully backed by a professional research and development program based on many years of hands on experience in the suspension industry.
Super Pro designs incorporate the latest technology in polyurethane as developed by the Super Pro Research and Development Team.
Design features such as bullet grooves, knurled and spiral bores and grease grooves ensure that the product performs to the highest standard without transmitting any excess noise, vibration and harshness (NVH).
Super Pro components are produced to the highest achievable tolerances for polyurethane. This is essential for the correct fit of each component resulting in the life of the product being maximised and to ensure that the vehicle componentry is not over stressed and damaged. All the steelwork used in the product range is precision machined for precision fitment.
Maybe JSutter should dyno these parts to satisfy all you "tuners" out there who come up with your nonsense! Stick with your neon lights.

Curb weight of a P11 is not that far off an A32, 100lbs different at the most. Also since the rear beams are nearly identical I dont see any issue here. BUT yes its a good idea to wait until I install them and try them out for some time.
The rear end does feel much more solid, and actually quieter than before. The *squirlyness* of the back end flexing around has all been eliminated. Sharp cornering is much more responsive. Taking bumps is where these bushing shine, making RR crossings a breeze to fly accross. I cant wait to replace the fronts with the SuperPro kit as well.
I'll drive up to maine and put some of these on my car...
Its not the inner sleeve that is reused, its the outer one. Its the big, thin, rusty one in the pix that stays, although I dont see how some one would get it out anyway. Its looks to be pressed into the trailing arm, the directions still say leave it be.

Cool. That's what I thought but I asked anyways.
BTW - I sent an e-mail to SuperPro's US Distributer asking for SPF1942K pricing. We'll see what this guy says. Maybe cheaper than $66 pricing (per set) can be obtained.
Possibly from my end. Depends on pricing and availability from Global Performance Parts. I do not know what Sutter's source can do for group deal pricing. JSutter? What say you?

One of you will have to contact either octotat or as Sloppy is doing, the distributer. Octotat had GD on the other forums, at one time pricing was so low that he was told never to sell them that cheap.
ALSO There is possibility that ES makes the same bushing. It was listed on sites for the longest time but was "never produced" according to ES. Some one out of the states bought one so it does exist. It looks like the 5th gen bushing, so to make sure it will fit they are measuring it for me. http://www.b15sentra.net/forums/show...=126181&page=4

All- Suspension Restoration Parts Company carries every Energy Suspension bushing made. All of them. They have been trying to get ES to confirm the 7.3120 Rear Trailing Arm bushings will be made and available. They have never received a single 7.3120 bushing. Here's what ES Chief Engineer told Suspension Restoration Parts Company:
"10-04-2005 Energy Suspension says, "We are in the process of building and releasing the 7.3120 set. Approxomate release date 6 - 8 weeks".
Sorry for the confusion.Steve Blakely, Head Engineer for Energy Suspension.
And follow up "reports" from Suspension Restoration Parts Company:
3-17-2006 E.S. has still not made the 7.3120
8-2-2006 Still waiting
11/06 this part number is back in the latest catalog. We have re-ordered again. We will see if they actually have it in production."
Long story a little shorter....don't hold your breath (ever) for Energy Suspension. They can never hit a date and are just plain full of B.S. guesses when it comes to release dates.
BTW....no word back from Global Performance Parts yet. I'll post as soon as I know something. -Sloppy

Careful with that statement. Poly and metal bushings can create binds whereas rubber bushings allow for better 2 & 3 way movement in some applications. There's numerous examples (not just A32) where replacing worn bushings with new rubber OEM ones is preferred.
Thanks JSutter for confirming the fit for everybody!

I've never encountered this problem but I guess it can occur.
Out of couriosity have you seen this occur with cars modified for speed and handling?

Examples: Installing all the rear ES bushings on a B13 is not a good idea, too much bind, so you must select certain ones that help.
The A32 has bushings in the Scott-Russell linkage that shouldnt be replaced with stiffer ones. They are designed with play for movement as the suspension travels. http://www.se-r.net/about/g20/scc/oct98/tb.html note the 7th paragraph
Stiffer chassis on the other hand, you can never do wrong there.
