Put mine on like 3 weeks back. They look good. Also he might notice cause the springs are green and stand out. Espically if you have rims you can see them easly in the back. My ride quality is great but i put some new KYB shocks on at the same time. so idk about stock shocks.
-one more thing, takes a while for the springs to setttle. more than a week. at about 3 weeks mine are finnaly looking good.
