Finally, proper lowering springs specific to Si Coupe & Sedan - by Eibach

[jaydubz79]

The spring doesn't have anything to do with the ADS. All that system does is turn a valve that makes the struts/shocks a bit stiffer. Slightly shorter/stiffer springs will not affect it. Extreme changes in ride height or spring rate will affect long-term life of the dampers just like any other car, but Eibach Pro-Kits have never been extreme.

But does Eibach address the ADS at all with this particular kit?

Go to eibach.com. Use drop-downs to select a 17 or 18 Si. Read details.

"Tested with factory dampers."

I had read that some people were experiencing CV boot issues with these. Why would this happen?

So, we don' need this camber kit for front? If just installing pro kit.

When I dropped mine on the Eibach ProKit my camber was still within spec on the fronts.

The rears you'll definitely need a camber kit. Results may vary, but I had about -2.0º camber on each side

I meant to say with pro kit. Cool, tks.

Any time you mess with suspension outside of factory specs it's a risk. Doesn't matter the car. Best bet is if you want to lower your car, do it properly and get an alignment, and have a trustworthy shop check all of your suspension parts on the occasion, or do it yourself. I am honestly not shocked these cars have issues with even mild drops, they are considerably lower than a lot of factory Hondas I have driven.

My Eibach Pro springs will be installed in 10 days. I have adjustable rear camber arms and I also have adjustable ball joints for the front. I don't need much....but a little extra clearance up front will help my very slight rub with my wheel/tire combination.

I have now had my Pro Kit springs installed for a solid week (daily driven) and my overall impressions:

- it is slightly stiffer, honestly I thought it would be a lot stiffer. But pleased that it feels identical to stock

- car feels a lot more planted

- I need a rear camber kit (already bought it, need to install then get an alignment)

- my front rubs (more on passenger side) with extra passengers or when I hit dips or bumps. It rubs on the fender liner tab area closest to the side markers.

- I took before and after measurements, about an inch all around (will post exact #’s later)

My wheel specs: 18x8.5 35mm offset with oem good year all seasons 235/40/18

Thanks for the update! Looks like 18x9.5 +40 on Eibachs is impossible without more modification ..

I still think you’ll be able to run that size. There are several members that have a similar size wheel set up with a more aggressive drop (eibach sport line).

Unless those that have such a size aren’t really reporting the rubbing or modifications they had to make?

The rubbing I have looks like it can be remedied by shaving the tab or completely removing it. Which I plan on doing this weekend.

Is it just me or do all these prokit pics look like rear is lower?

It probably is by a smidge... if anything the camber he has in the rear gives it the illusion of being lower as well.

When I installed my SPC camber arms & realigned, it looked much better and more even all the way around.

Had my Pro Kit springs installed, no camber correction needed so far after the alignment. Everything seems good!

Hows the ride quality?
