Long story short. Eibach didn't send sleeves for rear shocks at upper mount with my pro kit springs. The kit did come with bump stops. Plus, my installer couldn't get the Honda sleeve off cause it's crimped, so dust boot wouldn't come off..

Today I put car up on one side, and took out the right rear shock. I was able to get the crimped sleeve off and was ready to put the Eibach bump stop in but it was loose on the shock. The wrong ones were on the kit. Now I just want to put it back OEM Honda 'til I get the right ones.

So here's what I need. Can someone post a diagram or pic of the shock pieces so that I put them all back in the correct place? Can't bel;eive I lost track of the job this way but I saw red and now forget exactly how it's arranged.

It's the right rear oem Honda shock for 2012 Si Sedan. Thanks. Meanwhile I'll hunt around on the net to try to find a pic.
 
Thanks folks. That's what I needed . . . it's back together and fine, but still needs the correct bump stops from eibach. I'm really disappointed in them. First the lack of new sleeves, then the wrong bump stops (I should have checked the part numbers against the instructions. would have noticed this sooner).

did you buy 9th gen eibachs?

Yup. Eibach Part No. 4088.140 (have that memorized now) for the 2012 Si sedan. I ordered it through Amazon, crazy good price. I don't think the mix-up was by the vendor, because the box was clearly unopened factory issue.

I think Eibach is having issues with some of their brand new setups (instructions suck, QC, etc) because their product manager has been out on leave unexpectedly for some months now.

So I'll call them Monday and request the proper bump stops. Longer range, I hope some company, Bilstein, Koni, KYB, decides to issue a shock for our car. I don't think anyone does except for coilovers. I know Eibach has no shock for us because I asked yesterday when I spoke to Dave in tech support.

The 8th shock with fit according to RedShiftChris and Koni has a set. I plan on getting them. Why do you have the rear shock off if your doing the springs? I bought the 8th gen skunk2 springs and the 8th gen isolators from Honda and everything works good. There's just a little rattle up front which seems to be common with this.

Prob makes it easier to remove the spring. Although removing the bottom bolt on the shock body would of sufficed rather than removing the entire thing.

I had the springs done at a shop already, but the installer couldn't get the oem steel sleeve off the oem rear shocks to get at the bump stop. So he just put the oem shicks back in. They estimated 2 hours to grind the dimple out of the sleeves to get them off and switch the bumpstops and put the dust boots etc. back on. I decided that was way too much time and tackled it myself today. It's been years since I changed shocks, but I know how. I never had to get inside them before.

I got the sleeve off the right rear shock, not sure if I needed to grind it off as I saw fine threads and twisted it off with a 5mm allen key in the end, pulled off the dust cover and put on the one that eibach included in the spring kit. Only the rear springs on the 9th gen need the oem bump stops changed to shorter ones. The front oem stops are reused on the front.

So when I dropped the eibach bump stop on it was flopping around. Too large a diameter hole. Compared the part number to the instructions and . . . the kit had the wrong ones in it all along. So I have put the oem bump stop back in, used the new eiback sleeve, tightened it all down and it seems fine. Much afternoon wasted, have a huge headache, need a drink, and I think want to upgrade the rear shocks rather than hassle with tearing both both shocks apart again, etc.

That's the nutshell version.
 
Maybe I'm not clear. The Eibach 4088.140 pro kit springs for 2012 Si sedan come with new, shorter bump stops for the rear springs, and they are a PITA to change out.:beer:
 
That is really strange that Eibach would have you install different bump stops for the rear shocks. VERY strange... in fact I've never heard that before. Why wouldn't the stock bump stops be enough??? My tendency would be not to even worry about it. Unless the Eibach spring starts to coil bind earlier and they don't want that happening or something? Is the Eibach bump stop longer or heavier duty than the stock one?

And btw best way to remove that little sleeve on the stock shocks is to clamp it in a vice and drill the dimple out. It takes less than a minute even using oil and going slowly. Step 7.5 in the link below shows the sleeve drilled out. Hope that helps..... :)

Thanks for the reply Chris. This is a first for me, having to go inside a shock, but the Eibach bump stops provided in kit 4088.140 are about an inch or so shorter than stock, and they are to be switched in to replace the oem stops. In most other respects, they look the same as the oem stops, but seem to be denser, similar material. And yes, your advice on drilling the sleeve will come in handy when I get back to this job, because I blew through three grinding bits on a die grinder just for the first shock. I also nicked the threads pretty good and had to run out to home depot for a 10x1.25 bolt to re-thread about five lower threads. Didn't want to try that with the stock nylon bolt.

While I have your attention, I am considering just pulling the rear oem shocks and going with better rear shocks that need no alteration. I understand that the adjustable Koni sport shocks for the 8th gen would work (?), but they are real expensive (about $260/pair). Can you think of or recommend an alternative shock for the rear? Recall that my suspension is stock, other than the springs.
 
The bump eibach bump stops can be seen here. The oems have one more smaller "rib" at the bottom.
 
oops. here . . . the oems have four total sections, not three, now that I look at the two sections on the eibach.

I think the new springs don't bind like the old ones, so maybe to prevent the suspension from bottoming out harshly, they include new heavy duty bump stops. Since the op said the new bump stops are shorter and denser, that'd be my guess.
 
If they are shorter and denser, then they will be more harsh. Still doesn't make sense. Swapping them is not easy, so it makes me think they consider it important.... but I cannot figure out why.

If it were my car, I'd leave the stock ones on until I figured out why.

Well if they aren't hard enough, the bump stop will compress all the way and the shock will bottom out. If they are too tall, you won't have as much usable travel
