So, either both ways are fine, or one of you has them upside down The reason I brought it up is because I have similar looking springs, where the lower coils are closer together than the higher ones and I installed mine according to the DIY above. Also, the ends are not exactly the same, since one end gets a rubber cap and the other end sits in a groove on a plate on the axle. One end brings the coil almost to a circle, while the other kind of ends open. So at least from a geometry perspective, it's not the same. But it might be just fine... I don't know... that's what I'm trying to figure out

The only disadvantage someone mentioned about this mod is that you might get some rubbing because if the modified geometry. Look above on this thread for a picture. I don't have that problem on my hatchback with a mild drop (1.4") But if you don't do it, you would either have to adjust the alignment with some spacers or you will get uneven tire wear.

Anybody had a chance to see what sort of changes the pivot change makes, compared to not changing the pivot?

Yeah! I shifted up the pivot point of my rear arm. The very first impression given me is, WoW!! My ride feel so much more balance especially on the rear suspension during hard cornering.
In the past after i drop my ride with Tanabe NF springs, i do gain the look of it but somehow i lose a little on the "corner handling" & "cornering balance" if i corner really hard. The reason is due to the "super soft" spring rate of the NF spring gave & i bear in mind that NF springs is strictly meant for "Comfort" usage. I am already used to it and live with it of the "soft" & "floating" cornering of the NF springs!! Till yesterday i change the rear of my suspension pivot point, while i'm testing it, i smile to myself!!!!!! Feeling "unbalance" & "floating" in the hard cornering will be a thing of the PAST!!! Thank you, Yaris World & all mates to share in this forum!! As i'm not sure how the rear camber or toe angle change after shifting to the upper pivot point. Below are the points i figure it out after the mod, i really can see the rear wheel being "extend" to the rear end. Meaning having a longer wheel-base after the change. Below are the points i thought which really make sense to have the longer wheel-base after the change. 1. Once our ride is lowered, our rear arm will move/angle "upward" where this will "shorten" our wheel-base a little depending on how much u lowered. More lowered = Shorter wheel base 2. In order to enjoy back the near stock/longer wheel base, where this addtional hole is there for. Upon shifting the pivot point higher, the arm will now have the most "level" & "parallel" to the ground, for this we'll gain back the stock/longer wheel base. Please do not frame me if the above pointers are wrong or does not make sense to any of you. Pls correct me if i'm wrong. As i'm still learning and want to share with you guys with my logic.

For those who have done the mod, even though it's much more stable feeling now while turning and cornering, would you agree that it seems the rear end ride comfort is a bit more uncomfortable/harder feeling?

It is all depending on what ur liking & habit to drive your Yaris. More comfortable ride = Less stable ride OR Less comfortable ride = More stable ride |

I think it puts more force on the springs i could be wrong. When i put my springs back in place it took a heck of a lot more effort than before. I think they are being compressed slightly more somehow thus allowing a slighter higher spring rate?

^^
That's exactly what I was thinking. It basically preloads the spring at a higher rate, giving it the harsher feel and better reaction. Why did you have a hard time putting the springs back in, just curious? Mine never fell out or needed to be moved/adjusted |

But i think it does preload the spring more. I can feel more harshness at higher speeds especially. But man its so worth it. Makes me really wana get some new shocks now. Should have taken advantage of the 10 percent off deal.

Apexing Egg!!

so i did this yesterday. i think the car sits SLIGHTLY lower but that may be an illusion.
as for the ride, the car is more comfortable! that is really the thing i noticed the most! I didnt notice a huge change in handling, but i also just installed an LSD which i only drove on for one day, which made a huge change in handling. over bumps on the interstate, the car is not nearly as jolting, it was quite pleasant driving it home! which is very unusual, after about an hour in the car, the body starts to feel quite fatigued. as i said already, i didnt notice a huge handling difference, but that is probably due to getting to used to the LSD (which is very different than the car was before.) another thing, i think an alignment using the SPC shims is a good idea after this mod. i think there is enough slack there to create some subtle alignment changes. once the bolts are torqued down, they beam is in place. then i would correct it with the shims. great find!

I don't see how this can preload the springs at a higher rate, since it's the weight of the car that's loading the springs, which is the same. The only thing that changes is the angle of the axle plate versus top plate, which hold the springs in place. With the axle down those plates are almost parallel, with the axle up the plates are at a certain angle.
