    I was recently looking in to changing the suspension on my 2004 Prius to adjustable coil overs, most likely the Megan racing coil overs. However, after looking around on this forum I’ve been wondering if the aftermarket coil overs for the corolla/ matrix will fit. There are a lot more options for the Corolla/matrix then for the Prius.

    I’ve noticed that many on here have eluded to the components working ie sway bars, but what of the struts themselves?

    Also if it is possible has anyone tried it?

    I think it should be similar or even the same. Only difference is spring rate and shock setting.

    Fair enough, the Corolla coil overs are significantly cheaper than anything I’ve found for the Prius so I’m concerned that no has tried this out. I did notice that the oem part numbers for the struts are in fact different, so that does concern me a little. I would still love to find someone that has tried to fit a Corolla strut into a Prius.

    If you're in the San Fran Bay area, ill go to a salvage yard with you and we can test that hypothesis out 8)

    If I had the time I'd do that myself, trying to even find time to do research is hard enough. I did notice in a post by member prius70 untitled "going lower...inserts" he mentions in passing about using corolla struts and how smooth they are, the fact that he can push down on the front end and have it come back up. Something along those lines. It was such a brief mention that I missed it a few times I read through.

    So with that single reference I might just have to bite the bullet and order some corolla lowering coilovers and hope they work out with little to no modification.

    Sometimes different part numbers don't really mean the compatibility. Just a kind of classification to be easily found.

    Good point, I’ve studied the various pictures of both struts and they do look rather similar. If I do end up getting the Corolla suspension I’ll be sure to post any updates.

    From my information, gen 2 Prius platform shares with Corolla but with some modifications. Front and rear suspension parts are essentially the same as Corollas but with different settings. For example, diameters of sway bars, different spring rates and shock hardness. on Prius, for the purpose of weight distribution and ride quality. Toyota engineers made some changes on it but generally speaking, if you are not expert in the area, you can not find significant or even slight difference between them. They should be compatible.

    Thank you very much caravan, at least now I’m more confident in purchasing the coil overs. If I do get them, like I said, I’ll post the results here.

    Eric, did you ever get a chance to continue digging on the Corolla suspension items and if they will fit your Gen 2? I'm in the same boat and searching for answers on suspension upgrades.

    I'm afraid not freefall, I did just talk to my mechanic today in regards to the suspension compatability, he said that they are very similar but there are subtle changes to the coils and spring rates. But when pressed about if they would mount with all the existing bolt holes he was unsure. So I'm still in the same boat, I'm leaning towards just biting the bullet and getting the corolla suspension and trying it.

    Erik, I wrote another reply earlier today in response to a thread about Suspension Upgrades. You should be able to find it with a quick search.

    There are so many good posts here from the past, it can be overwhelming. But, several years ago, Justdidit really tricked out his Gen 2 and used Bilstein Shocks and Struts (Bilstein B8 Series for an 03 to 08 Corolla). He took great picks and also posted part numbers.

    The only difference is he was interested in lowering his Prius (and did an awesome job). But I'm interested in raising my car an inch or so for better ground clearance and still want to upgrade with a quality suspension system. Type in Bilstein and you should be able to find that 2 or 3 year old thread.

    Whoever designed this site really deserves a big thanks bc it is very easy to find information (if it's contained in a prior thread).

    The Corolla struts will not fit a Prius. I spent a bunch of time in a you pull it junkyard yard trying to figure this out. The mount to the steering knuckle is where the parts differ.

    I have found a solution for lifting and stiffening a Prius.

    I just want to verify that you are stating that the front wheel knuckles on Toyota Corolla 2003-2009 model year are different geometry than Toyota Prius Gen 2 model year 2004-09.

    Yes,

    The mounting surface for the strut are different thickness.

    Maybe?

    I did not compare the rear struts when I was at the U Pull It yard. Looking at Rock Auto's spec shows they are very similar.

    Another option to look at would be springs from a 2005 or 2006 Corolla XRS. This was a sporty version those springs might firm up the suspension without raising or lowering a Prius.
