I should have clarified this from the beginning. The Mirage springs are indeed longer but they are so soft that the weight of the car compresses them so much (without passengers) that the ride height with them is equal to the shorter springs. This is because the shorter springs are far stiffer and barely compress with the weight of the car. They arnt going to pop out any time soon as we had to use a floor jack to compress the rear beam to be able to thread the shock bolts. To anyone concerned about this, we managed to pull the ORIGINAL springs out by hand without undoing anything, just lifted the rear of the car and pulled them out by hand.... We tried doing the same with these springs, those will not be coming out in the same fashion. The spring will not suddenly become shorter and the shocks will not suddenly become longer with rotational forces, inertia etc. The rear beam will only drop as far as the shock will allow, and mind you if this was ever a problem there might be more than 1 tiny bolt holding the beam to the shocks (common sense engineering) lol.

I've been doing some digging, looks like the 2012 and 2013 Yaris part numbers are the same. Prior years are different, and I believe 2014 is also different. So If you want to try this mod look for 2012 and 2013 springs. Not sure about 2014 onward
The 2012 US based Yaris SE trim came with a sport tuned suspension option, and what I can only assume were slightly stiffer springs but I have not been able to locate those online.
Also, I have found rear spring part numbers 4823152F30, which is the one offered at the few US based Toyota parts dealers I have looked at and also part # 4823152F40 which is a Mexico/Rough Road spec spring, which I am assuming is slightly softer??
OP - Do you happen to know the part number of your springs?
I just ordered the 4823152F30 rear springs, should have them installed in about 2-3 weeks. Will report back with perhaps a new thread regarding ride and handling.
I cant speak about the se model because we dont have it in pr. As far as the other yaris im 99% sure all years will work, part numbers may differ but are identical. I currently have 2005 yaris ksport coilovers installed in my 2013 yaris and previous to that had 2010 springs in it. They are all interchangeable minus the se which probably just has stiffer dampening.

I can verify this myself. My brother and I jacked the car up and just pulled the factory springs out by hand. The slightly shorter Eibach springs had to be compressed a bit to get back in. The factory springs are extremely soft. Even the front springs did not have to be compressed. We did compress the front to be safe but they are so soft that it was not even necessary.

Shocks are the right length but different mounting bushing will not work without bushing swap.
OEM Yaris shocks are the same Tokico crap, but they are firmer so would reduce pogo effect. If you want to experiment with drilling out bushing to right size get Monroe OE Spectrum (much better shock) for Yaris or xD and then drill to fit stock bolts good luck.
EDIT: I don't think springs will fall out since shocks are very close in length.

This is very interesting. there was no way I was going too be able too simply pull the rear springs out by hand without dropping my shock. I even ran Honda fit springs for a while that if I recall correct were slightly shorter, and they were locked tight.
I also included a picture of my factory front spring next too an eibach spring. Clearly the factoryy spring is easily 2" longer, plus the 3/4" or so the eibach squished. It obviously would be under some pretty high pressure, because i cannot collapse the spring down 2" by hand
I have a 2015 I bought used. I wonder if different years got different leagth springs, struts or shocks, if my springs were changed prior to me owning the car.... or maybe I'm remembering wrong?? Herm.
So.... OP, any thoughts after a while of use???
