Hey chris how can i get the 8th gen rear upper isolators to fit on to the 9th gen civic? Does the factory rear isolator of the 9th gen just pop out? And the 8th gen one goes right on it? Or how does it work?

Yeah it just works. Or you may have to cut the middle out...cannot remember exactly. It's very simple. Only thing is most 8th gen rear springs on a ninth gen will make the rear sit too high, so you have to take about a coil off the rear springs to make it right...which works great with many springs if you don't mind doing it.

So if I saw like for example coilovers that says 2006 to 2011 civic si abc companycoilovers , I can pur chase aftermarket 8th gen coilovers but still will be able to install then on my 9th 2013 si?
Without the sway bar and little modification on the bracket issue ?
Let my know guys Thanks GOD bless and take care

The 9th Gen Si struts have lower holes that are bigger than the 8th Gen. So, you have to get 16mm to 14mm reducer washers to make the strut bolt holes "smaller".
Ksport Adjustable Coilover Systems, Camber Kits and Suspension Products | Ksport Store

Those will work and are as cheap as anything I've seen. AMR Engineering has some too that are more expensive. I think this must be what you've heard of as a link kit?? Not sure on that. You'll need 8 washers total (4 per strut).

Otherwise they fit fine. And you just won't use the swaybar bracket on the strut because yours is on the lower control arm.

Hope that helps. :)

Hi Chris, need some professional opinions from you. I just purchased a pair of front struct from a 2014 Civis Si. I am hoping to use it on my 2008 Civic Si. Do you think it will be a direct fit other than I might need some 16mm to 14mm reducer washers? By the way, do you have a picture of the "lower holes" that you mentioned.

Doubt Chris is on here much anymore however he's always been quick and helpful via email. [email protected]

Hi All,

Thought I would share my findings so far with the 9th gen Civic Si suspension I have recently inspected.

1) Camber plates: The front upper strut mount is identical between the 8th and 9th gen cars; so the ASR plates will work on 9th gen too.

2) Front struts:
- are very similar other than the swaybar tab and brake line brackets at the bottom.
- shock max and min length is about 1/4" longer (very similar); so the Koni insert length will work well. Koni insert fits perfectly in 2012 housing and is 1/4" shorter than the stock 2012 shock, which is fine for anyone wanting to lower the car.
- pin thread and length are the same. (pin is threaded part at top of shock piston)
- lower spring perch is approx 1/8" higher on the body (not too much different but looks slightly higher). perch stamping looks same as 8th gen Si perch.
- strut bearing is different and uses separate upper spring seat part number (not integral like on 8th civic), but the 8thcivic bearing (and integral spring seat) fits perfectly on 9th gen top hat (because the top hats are identical); so retrofits will be easy if needed. Interestingly, there are no bearings is the 9th gen strut bearing... it's some sort of plastic flat bearing and lube that has no moving parts other than the top moving relative to the bottom (and it's very thin and weighs almost nothing).
- the swaybar mounting tab on the 9th gen strut is going to make machining off the lower spring perch more difficult where needed, but it is still doable with manual removing of the spring perch first with a cutoff wheel and then finishing on the lathe.
- strut to upright "knuckle" bolts are larger on 9th gen car (8th was 14mm and 9th is 16mm).

3) Rear shocks
- rear shock is basically identical, and the Koni part will fit perfectly.

4) Rear spring
- the rear spring is slightly different from the 8th gen cars. The ID at the bottom is the same as 8th gen, but the top is not the same. Where the top ID of the 8th gen is significantly bigger then the bottom ID, on the 9th gen, the top is only very slightly bigger; so the upper mounting method must be slightly different. I need to see an actual 9th gen Civic in person before knowing the specifics of how a coilover will fit the back of the 9th gen.
- spring length appears to be the same; so current rear spring specs for coilovers should work the same on the 9th gen car.


And what does this all mean? It means that a drop spring kit for the 8th Civic does not fit the 9th Civic. It also means that a Koni based coilover kit for the 9th Civic is just a few relatively small changes from 8thCivic parts away from working perfectly. But I need a car to know for sure.

Anyone interested in making a 9th Civic available to me to look at. I can make it worth your while. Contact me asap.

Cheers,
Chris
