I swear Koni had a part number which includes both front struts and rear shocks as a kit but I can't find it on their website or anywhere else on the web. Does anyone happen to have it? The prices for buying them individually are insane! This is for a 2010 Prius (regular, not C or V)
I've studied the cheapest shocks and springs and the most expensive shocks and springs and for a car like a Prius what brand you choose is just about as meaningless as what brand of motor oil you choose. Focus on best price, not which overpriced brand labels, that like motor oil, are often all made at the same facility and are nearly identical other than the label.
I am currently using a kit from Tein, which is height-adjustable. It is very good except that the rear body must be lowered. Generally, it feels very comfortable when driving on the road. Even if the tire pressure is high, you will not feel any bounce. It can adjust the height of each pillar, so the corner weight balance can be adjusted. It would be better if the rear spring k value could be higher.
In addition, it is recommended that the toe angle should be the + value recommended by the manufacturer, which can offset the tendency of the tire inclination to increase to a certain extent. If it is 0 or negative toe angle, it will produce excessive lateral moment on the shock absorber strut, accelerate the wear of its linear bearing, cause smooth expansion and contraction, and affect the shock absorption effect.
