Scored a set of new Koni rear shocks from a 914 enthusiast that had an extra set. Decided to set up for adjustable coil overs. Before installation I though they deserved a photo.

Who's coil over conversion is that?

Posted by: tailwind22 Oct 31 2018, 10:07 PM

Got the springs and rest of the conversion from Paragon Products.

Cool! So I could take my sport Bilisteins I have on rear and get that same conversion kit and put them on rather than use the stock springs?

The kit I got was specifically for Koni. If the Bilsteins were the same diameter I am guessing it would fit.

Rebel Racing has Billstein kits.

Thanks Mark! By going a bit more stiff I should also be able to raise up the rear by a bit as well? if not I will have to lower front a bit as the car sits just a bit lower in rear compared to front not sure if its high in front or low in rear.

The kit let’s you adjust height independent of spring stiffness but even regular Billstein shocks let you adjust height. But the regular ones require removal from the car and a spring compressor to move the clip up or down the shock body. The “kit” let’s you do the fine tuning on the car. Watch the video. It’s very well done.

Thanks Mark. Glad my busted knuckles can serve the greater good.

FYI, the Bilstein Ground Control kit I bought is also available for Konis. From what I understand, most of the adjustable kits work exactly the same way. The main difference is in the choice of springs...and whether or not "helper" springs are also involved (like Tailwind has in the original pic). I was told by Ground Control that, for street use, you wouldn't notice a difference with "helpers".

I have Sport Billy's all around and I got my kit from Rebel Racing.

Talk to Clint....he knows 914's well.

Posted by: mepstein Nov 1 2018, 09:38 AM

It can really depend on your roads. East coast roads ride a lot harder than south west but I agree, Clint knows this stuff really well.

I don't think The helper springs were around when I did mine. Do just they just collapse underload and help keep the springs under light tension pressing to the top caps? They must not have much to do with the big spring # rating. Bit of a hassle settling the suspention after jacking the car up. With mine, the threaded collar was supposed to slip over the land on the shock body. I figured that out the second time.

MHO. For a not hi-po engine, stock anti/sways f&r, stock torsion bars and not some AX weapon, 100 lb springs work really well. stock ride I guess.

Posted by: DRPHIL914 Nov 1 2018, 10:23 AM

I agree, the sport bilisteins are very firm and I have stock springs with them, and stock sway bar etc and its super firm and tight, so with a stock motor even if I were to AX it I don't need more stiff springs, just a slight height adjustment. I can put the bilistein retention spring up a bit higher, I am in the middle ring now, if I go up higher and I have been too high before then its really bouncy sitting more on spring than shock. I guess at that point a more firm spring would be better for less bounce but then very rough/firm ride, and keeping in mind tire type and size make a huge difference. I have had 14" fuchs with stock size tires and that was a good bit softer ride than the 16" fuchs and my 205/55 Bridgestone Potenza tires. So the whole combo matters. good luch on your search and sorry for the hijack, for me I might go up one ring setting and see how it sits and rides. those coil overs with springs from Rebel are about $320, and lowest spring set is 200# which I think would be too firm for my 90% street use, and the occasional mountain road carving .

correct; helper springs are only to keep main springs from clanging around loosely when the suspension is unloaded.

those coilovers the OP posted are very nice!

Posted by: rhodyguy Nov 1 2018, 12:49 PM

Stupid ?. I see rebel offers 2 sizes. Where does one measure for the spring diameter? Spring itself or simply measure the threaded collar.

Posted by: zig-n-zag Nov 1 2018, 02:20 PM

I have the same Paragon kit mounted to Koni 8241 1050sport shocks.

The front inserts are 911 Koni 8641 1039sport, which fit either late Koni struts or late Boge struts with the proper strut body nut. Paragon could not re-valve to 914 specification, and recommend sending them back to Koni.

Yep...guy shows off his shock and we want to talk about springs

Posted by: rhodyguy Nov 2 2018, 07:20 AM

They look swell.

Posted by: Olympic 914 Nov 2 2018, 07:32 AM

I am inspired....

Currently running KYBs with 100# springs and was planning on getting Bilstein for the rear. but now I am leaning heavily towards the adjustable Konis. and a spring setup like OP has pictures.


What are the thoughts of mixing Bilstein fronts with adj. Koni rears?

Posted by: burton73 Nov 2 2018, 03:29 PM

You can get the adjustable perches for Billstein’s. I got these for my V8 car several years ago. It was like $500. For the full set. Bills, Rebel racing adjustable perches and new racing springs and all the parts.

Just for reference not for sale.

Thanks. I'm getting some helpers.
