Rear Suspension Adjustment - Extension

[dtla1]

So I know that Ohlin's make a nice extension for their shock adjusters, any thoughts on solutions for extensions on Koni shocks (TC Kline Coilovers in my case)?

I've seen a couple of DIY's where they take the white plastic Koni knob, push out the insert and rig up some sort of extension (one example I saw was a piece of metal conduit/tubing as an extension) so I was hoping maybe there were some more refined ideas or solutions out there?

Thoughts? Anything you've seen that might be the "best solution"?

[dtla1]

Anybody??

I did more internet sleuthing and found a 3d model someone had already made for an extended version of the koni knob (basically just a longer shaft... I said it). Sent that to a local 3d printing shop and should have a few of those just extended shaft 3d printed ones in my hand today.

You ever get the 3D part? I bought a set of extended adjustment arms made by rogue engineering I believe. The shaft could be cut to length and the part that goes on the shock has a set screw to hold it on. They weren’t cheap though (but they are metal and. Ice quality) and I ended up just keeping one in my trunk instead of permanently mounted. I have two small jokes in my trunk liner with a small cover that I pop off if I ever need to adjust.

Yeah I got the 3D parts made, work well enough. Biggest issue I see is that the ABS I chose to use is surely going to get chewed up the more I use them. The inside of the hole were the adjuster goes in is just going to get chewed up. I had 4 made though so I guess I have extras if that does happen. I've been trying to come up with a way to make an insert but nothing concrete yet. I think an insert made out of something like HDPE would probably work, just need to get a rod of HDPE, chuck it in the mill I don't have, cut a slot in it with a small milling bit I don't have. Then drill out the abs and graft in the HDPE insert.

IDK maybe the ABS will last long enough and I won't care. By the way, It looks like rogue engineering no longer sells that extension, any luck you might be able to post a picture or two when you get a chance?

Yeah I’ll try and get a picture to you in the next day or so.

I tried and gave up. Switched to truly external adjustable dampers.

You mean a remote reservoir? Not being able to adjust them quickly couldn't have been the only reason though.

Nah a bottom mounted knob monotube digressive. External reservoir was outside what I was willing to spend. Also switched as I wasn't happy with the level of after sales support from TCK, and ended up disagreeing with his suspension tuning philosophy after multiple iterations and failing to find balance I was happy with. I really don't think they were thought out with the N54/N55 E82 in mind, may be better for the N52 variant At the end of the day didn't want to buy another set from him.

Hmm, I haven't had any problems and the car seems super balanced, but to each their own obviously.

Just out of curiousity, which coilover did you end up getting?

Here you go. They are all metal so total overkill but they are well made. The middle bar is really long originally and then you cut it down to size. Also including a picture of the rubber plugs I am using to cover up the access holes.

Nice!! Those do look pretty good. Definitely good to have for future iterations if I decide to do something else.

And last question for you, what did you make the holes in the carpet with? Just like a 1/2 drill bit or did you use a punch of some sort?

[houtan]

I marked the location of the hole using the measurements @fe1rx provided in his ohlins suspension thread. Then I marked the approximate hole size using the plug as a guide. It’s been 3 or 4 years, but I think I used my dremel to slowly make the hole larger and kept test fitting until I had a snug fit.

Here are the plugs I used, 1" 1 inch Flush Mount Black... https://www.amazon.com/dp/B00PEZS37I...p_mob_ap_share.

The plugs are a little stiff, but they have never fallen out.

here you go, post 27. https://www.1addicts.com/forums/show...=Ohlins&page=2

Those extenders look great!

You provide details in your build thread?

Updated the front post. I have pictures and full details but keep running out of time to dedicate to updating my build. Really been slacking there. Thanks for reminding me!

4 years later. Thought I would post the Koni extensions I recently designed and printed.

[WrathOTM]

hey those are a neat idea

Those look great - how much for a pair?
