I have the MP3 struts on my protege 5 and I must say that I love them. I am going to be getting some Eibachs pretty soon to replace the springs. The struts are nice.
The MP3 struts fit the ES and P5s just fine. Not to mention, the rear MP3 struts have stronger sway bar mounting tabs. So if you upgrade your rear sway bar, you will have no worries about anything breaking.
