Tamago, my email address is no secret... write it down somewhere, that's the best way to reach me.

With your fab skills, you should be able to use a standard spring and just spin up some perch adapters for it. Might take some experimentation to get it to work right.

The Tein springs that I have wouldn't work for you without the Tein tender springs, and I don't have another set of those. The tender spring allows the spring to work with the odd angle that the lower spring perch takes as the suspension droops.

Hey! How is Silk Road doing 7kg rear springs? Anybody got photos of that setup?

once the perches get here, i'll most likely be doing exactly that, already have a 3" plug of 6061 waiting at the lathe!

You will need more than the useless rear shock bushing brace if you go with a coilover setup on the rear shocks.

you could groove the rear shocks and run compression rings for coilover sleeves. That is what I run on my Cobra in the rear.

With a stiff rear sway bar and coilovers you could punch right through the upper shockmount. You would at least need delrin upper bushings and possibly weld or bolt on a steel plate for reinforcement.

eye-to-eye shocks can be modified to accept spring perches :) if my Ksport perches don't work out that'll be my next step.

Yea that would make things significantly easier, you would probably have to get them revalved for this application, but that is not horrible.

Yeah, I was thinking the same sort of thing. That upper mount wasn't made to carry any weight. Even putting in a reinforcement at the top could just be moving the weak point to lower on the tower where something else will bend or break under fatigue. Now, if the car had a full rollcage and you could tie into that... that could work.

sounds like a great excuse to me :rofl:

Yea.. the shock mount might need to be boxed in completely. If I was going this route, that is what I would do.

do you have a link for this process? If not, could you explain more about grooving the shocks?

My idea is similar i think, i thought about simply welding on a collar to set the spring perch on.

i can groove them at my shop :)

however, Gordon at koni does not recommend doing this, as the outer shell of most shocks is not thick enough to withstand grooving/welding unless already equipped in such a way.

really? shit... what about a sleeve with the top filled in and a hole drilled into the top for the shaft. So the sleeve fits down over the shock, and the top (rim?) of the collar goes over the top of the shock where the shaft passes through the hole. Then, you can have another collar on the bottom of it where you can slide a perch onto it.

Does that make sense at all?

Shocks are not designed to be load bearing suspension components usually, so that probably would not really work either. If the shock was beefy enough to do that, you could groove it anyway.

Agreed. You woudl need to check with the shock manufacturer to see if this is even viable.

It is an easy process to groove the shock bodies though.

You dont want to be welding to shock bodies.

Pages 4-7 deal with the grooved shock body and the spirolock ring that hold on the coilover sleeve.
