Thread: SO, THIS looks very wrong.

SO, Overkill Engineering Motorsports made me a set of Custom Shortened Konis, Spec V inserts into B13 housings. I went to assemble these today with a buddy of mine with some Road Magnet Springs. One the rear, 4-5 coil s are compressed to the point of touching, and the fronts, several are to the point that they will touch as SOON as they are put on the car and lowered.

My previous setup was AGXs with stock springs. Should I just mount the RMs on the AGXs and take up a complaint with OEM? I have a feeling these were assembled wrong by them. What do you think? Crappy cell phone pic below (sorry, it's all I had at the time):

Far left is one of the rears, and the middle and right are the fronts.

They look like they were made for a shorter spring....ie. coilover setup.

Definitely, don't install that.

This is what my fronts looked like assembled (RoadMagnet Gen2 springs on KYB AGX struts).



And here is the rear assembled.


Your fronts look okay maybe. Your rears don't look good.
Your springs are on upside-down but other than that I can't comment 100% on anything else as I'm not familiar enough with the shortening process on the struts for custom shortened Konis. I thought the shortening was supposed to happen between the lower spring perch and the lower mounting bracket (keeping the same spring height and overall travel) but that would heavily reduce wheel/tire clearance so maybe I'm not thinking about it properly.

I have always had my springs tight coils up. But that is a different setup for a different car with different springs.

It would be an embarrassment if they were assembled incorrectly.

did u call OEM?

I sent Mark a link to this thread, and left him a voice-mail.

It is entirely possible that those CSK's were (accidentally) built for a coil-over application. While I understand the thought-process and generalities of a CSK, I don't know shit about actually fabricating/assembling a CSK.


Yeah, but shit happens with Custom Manufacturing. It is the very nature of the beast. If there was a mistake made, it can be corrected. Mark is not buying "off the shelf" stuff and re-selling it. He is literally engineering and building the products he sells.

I do know that I am going to have Mark (O.E.M.) build me a set of CSK's in the future, to utilize with my Hyperco's. Which should be identical (?) to a CSK built for RM's (I think....).

So let's give O.E.M. a chance to look at this thread and respond.

And...yes. Tight coils should be up, loose coils at the bottom. Unsprung weight factor.

Looks to me that the springs are just to far compressed, correct? When I cut the shocks I cut them at the 52mm mark. Then from there its just pushing them im. There are a couple things you can do to correct the height of the shaft to get more spring movement. One, how much thread is showing? Alot, if so you can space the mount off with a spacer and this increases the height of the spring. Two you can remove the shock from the housing and install a spacer on them bottom and get a longer bolt. When I cut the shocks I cut them to the Koni specs. Maybe are your springs cut? Looks to me like the springs are upside down, no?

Hey Mark it would probably help speed things along if you let us know where you shortened the front and rear struts.

Did you take out a section at position 1, 2 or chop the top off like position 3?
Or did you do something else?

Maybe this doesn't belong here, but just curious if those are spec v koni yellows in B13 housings in the rear? I ask because when Steve Foltz was assembling my CSKs, he said that yellows wouldn't work with B13 housings in the rear. I don't remember the reason why, or if something has changed in the years since then.

#3, I believe it was 52mm according to Koni.
