Marcucci,

There is always a balance to be struck between sway bars and springs for handling, and it makes sense that everyone is different. But the stiffer the sway bar the less independent the suspension becomes. That being said, it'd be great to have an adjustable setup so one can tune to what they like.

I just got my leaf two days ago, but I might rip the wheels off this weekend and take a look at the front sway bar.

Obviously the rear is going to be much harder to increase roll stiffness without changing the springs, and it will definitely alter the characteristics of the car to change one end in isolation. Ie, if you make the front end stiffer and leave the back end alone the car will want to push, which might be great for some people that it's not my idea of a good time. ;)

Agreed, for most people. I've never actually changed out a sway bar on one of my own cars- I just never felt I needed to. I can usually achieve what I am looking for with springs. Of course, I usually favor a much stiffer suspension than most do, which effectively eliminates body roll on its own. I will have to see, I am planning on going softer with this setup than I have in the past, this is a daily drive for me and with 3 blown discs I probably should stay away from a stiff suspension.

Yeah a bad back could make things unpleasant. I'd be very curious to hear what you end up doing spring/damper-wise, and any driving impressions. :)
Thanks,

Dave

Also, for what it's worth, the OE shock in the rear measures 1.75" wide at the base (widest part, barring the boot up top) and has just over 5/8" of clearance at the closest point to the body. That gives us a max diameter of just a hair under 3.0" for the OD of a coilover, mounted in place of the rear shock.

The fronts, from all the images I can find, appear identical (struts and springs). If there are any size/shape differences they have to be minor.

Great info. I will need to detach the rear damper at the top and assess the re-inforcing the tower has before I consider going coil-overs on the back. I've seen too many Datsun 510s where people convert the rear to coil-over, and proceed to punch out the top of the damper tower on the first big pothole they come across.

I was contemplating that. How about you take all that apart, and take pictures, and I will get spring rates for the OE springs? :)

Looks like there is another option coming soon from Megan Racing:

I'm not sure of spring rates but I am betting they will be similar to their other offerings, which will be similar to other stuff that's available for the LEAF or Versa. Should be comparable to what I was looking for in the first place.

So no one has tried a cheap set of b16 sentra lowering springs yet? The poster that compared sentra struts to leaf and found differences was using the b15 , an older sentra not the newest b16 sentra

The op did pretty thorough research showing that the same year leaf and sentra share front shock and spring design and that the leaf rear shock is similar to the Altima.
I feel inclined to just order some springs and test them.
These look worth a try , cheap enough.

Unless someone has already tried this. Speak now or forever hold your peace....

MrElectric - I like your style and am interested in the results. I've done a fair amount of suspension tinkering on my 2000 Honda Insight and am looking into the Leaf for my next car and will probably do the same if I get one. The Insight has virtually no parts shared with other Hondas so upgrades tend to be very difficult and require lots of trial and error. As an example, many Insight owners wishing to reduce the rear suspension bottoming out went with Daewoo Matiz rear springs sourced overseas. My Insight is running custom-built adjustable GAZ rear shocks and one-of-a-kind adjustable coilover front struts also built by GAZ. Considering the availability of the Tein and other coilover options already for the Leaf, things look relatively hopeful.

One thing I haven't found yet for the Leaf is a stiffer/supplemental rear sway bar. I made my own for my Insight, stiffening it by 60% over stock and the resulting improvement to turn in and reduced understeer made it well worth the effort.

With a few forum members willing to do some trial and error based research we will most likely find some suspension parts from other vehicles that can be used to upgrade the Leaf. Looking forward to hearing if you make the plunge and buy a Leaf. Having owned a hybrid before my leaf I can say that I really enjoy the full ev driving experience.
