Seen some posts about this so decided i was modding the mirage, So ive seen others cars that sit around 24.5 stock i have a bunch of stuff in my car I was sitting at 23 inches stock, now sitting 25
The yaris springs are a good bit bigger and much stiffer I don't think I have to worry about hitting the bump stops anymore (especially loaded down) it rides so much better and smoother now, handles better too, very pleased with the upgrade.
Was a very easy job I just electrical taped the top bushing from mirage spring onto the yaris spring. The bottoms were the same diameter so I left it alone.
Apparently 2nd and 3rd gen yaris use the same rear coils from my research. Hope this helps yall.
Video added now, not the best quality i put alot more effort into bouncing the yaris springs lol oops, but they werent hitting the bump stops like oem.
