Really Neat!! love the fab work... but to echo Leesvet concern;
" I'd be a little concerned about that welded stud cracking at the plate junction...."
I'd stress relieve that welded plate?? maybe 600 degrees in an oven then a nice slow cool ???
is there any arc in the position of the spindles as they move through their travel??
One last item to watch, the front drops after it all goes together. Takes a few good bounces to settle.
I have the same spring, with only the end tabs off.... it sat quite high... until the bouncing darnedest thing it just laid down??
Nice job Fun no doubt. Doing the same project with my God Son!!

No I have no concern with the weld cracking. The weld is actually just holding the rod in place. The plate has a slot cut in it and the rod is in it. Any load in compression or tension (highest loads the arm sees) will not put stress on the welds.
Also, there is no rubber or poly in the suspension so there is very little stiction if any. The upper control arms have heim joints and the lowers have del-a-lum bushings. The front settled slightly while rolling it back but I dont think it will settle any more.

It is a kit from Banski MotorSports but it was intended for the rear. Interesting adaptation though. 
The kit for the rear replaces the rubber or urethane donuts with a delrin hemisphere and stainless steel cap. The idea was developed with permission from Hardbar USA to use the same idea as their Pin Top Shock Mounts (which we have for C4s BTW).
I have played with a couple of different ideas for a front spring ride height adjustment kit. I have one on my car and can use it to adjust ride height and corner wieght my car if necessary. It's for use with the conventional front leaf spring whose ends ride on top of the web of the LCAs. The issue is having enough clearance to get the adjustment mechanism & screw in place and still clear the shock.
Looking good Kubs!

Sounds like it's well thought out, but be careful.
Not playing Nanny here, but watch that thing. It isn't just steering you need to fret about. The big loads come from braking loads.
Your going to have stress on a lot of plane sections there. Parts look primo. but be cautious.
The Fhb is a Z07 spring ... they didn't come stiffer in an OEM car.

Yeah I will be sure to keep a very close eye on it for sure! Yes the braking forces cause a moment on the arm that will try to rip it off the mounts. I did take that into account as well.
Im glad you all are asking such good questions! Makes sure I didnt forget anything.

It is nice work. and good [ New, Modern] C4 stuff won't be easy to find in the future.
One thing I'm still puzzled on, how did you figure the amount of castor change??? Looks like two or three degrees during the full travel??
does the spindle travel Iforward any on compression?? With thos Heims it looks like it would

If it works I might be selling some sets based on how much I can reproduce them for. I will keep you guys informed.
