made myself bushings &my complete suspension overhaul
well my front LCA bushings have been out for awhile and did a real good search on control arms, bushings, alternatives, and so on.
my conclusion, im sticking with stock arms, no camber kits, no prothane, no daizen, but made myself my own delrin bushings. For those who put performance first, stated by Alex Pfeiffer. he is the only other one that i know that is running delrin bushings on the SC.
for the dimensions, i was lucky enough to have gotten an incomplete set of daizen bushings from another CL member, which i will be using to create my bushings.
that being said, lets begin!
i attacked the front first, got two seperate delrin rods for the upper and lower.
half of a upper bushing about to get turned.
left bushing is my delrin bushing, and the right is actually a Daizen bushing. compare!
slide two over an inner sleeve and that makes one upper control arm bushing
heres another shot, left is delrin, unfinished. sitting next to a daizen bushing on the right.
heres a complete front set. later this or next week ill start doing rears!
i should have some rear toe control rods coming in soon and an extra set of front LCA's to work with.

Those look pretty damn good. 
Do you intent to lube these?? If so, I think you might want to take a cue from the Diazens design and add those (axial ?) grooves in bore, as well as the slight chamfered edge at the lip of the bore on the inside surface where the two halves meet. Those both allow the bushings to "hold" lube and fit snugly together without getting locked up hydraulically by compressing otherwise trapped lube.

Have you heard of the MK3 guys having issues with delrin bushings? It was due to the fact that some of the arms dont go just up and down on 1 axis, but also side to side? It wound up breaking arms and stuff... You may want to search it supramania... But looking good man!

&sadly, i dont have the time to bother making any camber kits/ eccentric cams that will change the adjustability of the stock bolts.

im glad you pointed that out matt, i really have to consider what you said, but best to my knowledge is our front control arms [upper &lower] only swing in 1 axis.

The arms can move in more than just 1-axis due to the bumps in the road and the forces that's associated with the impact. The thing that keeps the CA from moving side to side is your caster. Imagine having worn out bushings...the CA will definitely move everywhere!

GSteg, i understand, but isnt that why we have the outer edges that step infront and behind the CA? to cushion that lateral movement?
because it is delrin, its hard, and no more "cushion" compared to polyurethane and rubber bushings. but as stated before, this is for performance only, not daily i would say. theres no other way to find out than testing it though

The outer lip is not enough. Delrin will still compress to a degree. I can kick the control arm laterally and it'll still move, although not as much. Energy has to be deflected somewhere. When you factor in the forces on the road with the car traveling at X speed, there is a lot of moment/torque that the bushings will experience. What's the Rockwell Hardness value on your Delrin part?

by the law of energy, it does have to go somewhere. im no professional or genius so im learning alot here through my project and build.
the delrin rods i have are valued at m89/r122

up close &personal with the LCA bushings
getting rid of that rubber, burning it down doesnt get rid of it that easy, just makes it easier to scrape off.
pressing it in:
and bam:
