I would have to ask:
1) Why do you want them? What are you trying to accomplish?
2) What is wrong with the suspension system on your CT that you don’t like or are trying to correct?
3) Is your current suspension worn out or damaged and you are needing replacement parts?
4) Are these worth the $850 price plus $342 shipping, plus installation perhaps $400+, and add in an alignment? Now you are easily over $2K.
5) The warranties on these are 1 year. Most aftermarket struts/shocks like Monroe come with a lifetime warranty.
6) I am always dubious of ads that are mostly customer opinions.
7) Installing the wrong rate struts/springs can cause your car to lift up and/or dip down under hard acceleration and braking or have the opposite effect by not giving enough bounce give you a rougher ride.
