Ditto. In fact, I'd only need stiffer dampers; I don't really need shorter/stiffer springs that much. Less body lean and a lower look are both nice, but body lean is not what bothers me about the LEAF's handling, and I don't really need a lower stance.drees wrote:Would also be interested in some struts/shocks with more low speed damping to go with them, too.
Just to clarify: a torsion beam suspension does not necessarily requires a separate-spring-and-damper set-up (and thus not suitable for "real" coilovers). It happens that the LEAF has separate spring and damper ("shock") on its torsion beam, but there are cars with torsion beam rear suspension that have concentric spring and damper set-up, and thus can accept "real" coilovers. For instance, watercooled VWs up until about mid-2000s.drees wrote:EDIT 2: Forgot about the rear beam axle - not going to get coilovers on back there so springs/shocks are the only option.

drees wrote:Anything in that range would be good for the street.
I have no clue whether/how much negative camber would help with turn-in. On my VWs, I run more negative camber in the front to make the front sticks more/understeers less (since it would retain more negative camber); more negative camber does not seem to do much for turn-in response. For quicker turn-in, I run a small amount of toe-out in the front. Excess toe-out causes "wandering" at speeds, but my experience with my VWs is that with a small amount of toe-out (0.5 degrees or less per side) there's some wandering but it's barely detectable.drees wrote:Edit: If the information in this post is correct - it appears that it may have enough negative camber dialed in already, but a little more never hurt.
As indicated, the LEAF has about -1 degree camber and just about straight-ahead toe. It would appear to be "very mild" but that's just a guess, since there are so many other variables.drees wrote:Gotta find out what the stock alignment specs are - suspect the settings are very mild.
I wouldn't mind a less severe 4x4 look for my LEAF, but appearance is secondary to me. Ditto range, when it comes to suspension tweaks. I kinda doubt if there are any measurable changes in range resulting from a suspension change. A lowered LEAF might have less aerodynamics drag (though I don't know why; a lowered LEAF still has the same cross sectional area), but I wonder if it's measurable.ERG4ALL wrote:Are these changes purely for the looks of the vehicle or does anybody have any data that would indicate a slightly longer range (i.e. less wind resistance)?
That's a very interesting observation about less toe-in to increase efficiency. I don't have any complaints about the LEAF's behavior in day-to-day driving. It feels squirrely in the wind probably both from the soft suspension as well as from the broad-side-of-a-barn profile.ERG4ALL wrote:I suspect that the LEAF has a somewhat "squirrely" feel especially in wind is because they have limited the amount of "toe in" in order to reduce scrubbing and increase mileage.
aqn wrote:I don't know how much is "enough negative camber" I since my experience with VWs most likely won't apply to the LEAF, although they both have MacPherson strut front suspension and torsion beam rear suspension (up to the Mk IV's), given the differences in geometry, weight, weight distribution, etc. If I want to try a different alignment, I'd need to play around with different alignment settings. For example, on my A3 GTI, I ran -2.1 camber and 0.4' toe-out. For me, the jury is out on whether making the camber more negative would make the LEAF stick any better in turns, ditto adding more toe-out to improve turn-in response, because any alignment changes may just be lost in the under-performance of the tires. It's hard to say.
