Previous gen Echo shocks on current gen Yaris
I have researched this quite a bit, and with no definitive answer. I have a 2007 Toyota Yaris and i really want Koni's for it. With no progress in site, i have looked into the topic again. I came across a site on this forum with toyota part numbers: http://www.toyodiy.com/parts/ so after looking on there, i noticed that quite a few parts are identical, for example the nut that attaches to the strut, the knuckle that the lower bracket of the strut attaches to is identical, leading me to believe that they are nearly the same. The major difference is the sway bar mount. The sway bar mount on the yaris is a tab welded to the strut body. Thus that is the problem that must be a addressed.
The rear is the same deal, the rear upper nut is the same, and the beam frame thing is identical part number. This leads me to believe that they should mat up pretty well, minus the sway bar issue. So what is left is deciding how to sort out the sway bar issue, which should be as easy as having a machine shop welding on a tab for you to mount the sway bar endlink. If anyone else had ideas or inputs, or sees a flaw in my logic, let me know. Also, has anyone ACTUALLY tried using an echo shock on a yaris? ive heard alot of maybes, but no one really seems certain. Anyways, i have ordered a set of Koni's for the previous gen Echo, and I am going to give it a shot. So wish me luck, i hope this works out! But it may be more complicated that i expected, but lets hope not. Thanks for your input! Ken

What are you going to do about the swaybar? You don't want to be welding to the strut body. I haven't even looked under the car lately, but perhaps a speedway style swaybar could work and endlink mounts could be welded to the arms? Or you could weld a bracket on to the arms to accept a short endlink.
You reasoning seems sound, and it is worth a shot. Sounds like your biggest concern (aside from the front sway bar) will be the compressed and extended lengths of the dampers, but I would imagine they are similar. |

yeah, you bring up some of the concerns i had. i was concerned about welding onto the strut body, so perhaps instead, i could go down from the sprint seat instead? or like you said, relocate the second link mount to the A arm. Once i get the dampers and make sure the rest of it fits, i will tackle the sway bar problem. Thanks for the ideas though, the more the better.

all that for adjustable shocks? seems like a lot of work...

not so much the adjustability, but superior valving and the capacity to be rebuilt to different specs. most off the shelf dampers have garbage for valving.

I have a stack of echo shocks lying around, if you need any dimensions, let me know.

the stock swaybar endlinks are super long.. i don't see why you couldn't modify your LCA's to mount the sway from below instead of off the strut.
the $$ spent and time and headaches though.. and you could probably just keep an eye out for someone selling coilovers used..

welding onto the strut body is fine as long as you know what your doing. i welded a swaybar tab onto my bilstein shocks on my old 3 series bmw so i could use a M3 swaybar, no problems at all.

yeah? this was my original idea... I will probably go to a machine shop and have them take a look and see what they think. do you have any pics or thoughts you may want to share??

Well, i got a hold of some Echo shocks and struts. I unbolted my stock components to see if they would fit, and they WILL NOT. So we can finally rule that out. I was majorly bummed because that would have really opened some new products open up for us.
Anyways, if anyone is intrested in specifics, the lower rear bolt is different. The stock yaris is very small, and the Echo mounts on a larger stud. The front strut holes are too far apart on the Echo. Other than that, both upper mounts look like they would work (but that may be a different story) and the strut spring perch look compatible. Thought you guys might want to know.

Photos would be helpful here. But, I'm not hearing anything that would make it impossible to fit.
In the rear, you say that the Echo uses a larger lower bolt. That can be easily fixed with a bushing to fit the smaller Yaris bolt to the Echo shock. In the front, use the Yaris upper mount. If the shock shaft diameter is larger, can the upper mount hole be enlarged to fit it? The front lower mounts, as long as they fit around the hub assemblies, shouldn't be a problem. Fix the too-wide bolt spacing by redrilling the lower hole. Unless I'm missing something, it sounds doable with some very minor modifications. |

couple problems with front upper yaris has socket head inside the top of the strut rod echo(and most other struts that have a 3bolt mount) has flatsided portions that the spring top hat fits into to keep it from rotating. also the bearing surfaces are different between the two shocks. the yaris upper mounts would bind up if used with echo shocks how much "off" are the lower bolt holes between the echo and yaris? next question... why are we sticking to toyota here? anyone thought about maybe a mazda strut?

back to other questions.. are there any other cars that utilize top 1bolt setups? VW golf ! Golf III that is ( 1994 or so)

never thought of that... what makes you think the lower mount will work? is there some sort of universal size i dont know about??

yeah, i was thinking about that. What i was thinking in the rear was either a sleeve around the bolt, or enlarge the actual bolt hole on the car. The later would make using a stock yaris shock impossible though, so maybe not a great idea.
As for the front, the distance i am talking about is the holes on the lower bracket. They are about a half to a full inch farther apart. Everything on the top looks like it will work. What i really need to do is do a comparison of the actual yaris shock off the car, but that means i have to pull mine off, figure out what modifications need to be done, and then put it all back together. and then test fit the new parts to see how it turns out. So anyone got any stock shocks they want to donate?? :D maybe i shouldnt give up on it quite yet...
