Update! Sorry guys it has taken so long. But yes I have redesigned the upper control arm once and everything is looking good. I do use sherical bushings in the upper housing BUT you can use polyurathane in the housing as well.
The kits will be double adjustable upper and lowers using hiem joints on both ends of the lowers and one end of the upper (spherical bushing optional)
As far as materials go I can use TIG welded chromoly OR TIG welded mildsteel...
There are also cost options on the hiem joints... A standard unit like used by most suspension companys or a stronger chromoly unit that has teflon bushings. (both are very strong... the chromoly units do not "rattle" on the street... makes for a quieter ride)
lowers are urethane coated much like a thin bedliner... it is very resistant to any peeling and also has a rough finish which is easy to grip and turn for adustments (I end up turning the bar with my hand many times with the hiems loose)
Right now I am in the process of dealer by-ins on behalf of myself so I can buy hiems/rodends/steel materials in mass quantities and also building a webpage with an online shopping center. HAHAHA honestly it is that "transition phase" from going from a dream hobby to a substantial business. I want it to go as smooth as possible and make the best products as possible. Before I sell there will be 25 chromoly kits premade and ready to ship.
I am also offering a lightwieght manual rack kit... for g-bodys. and IC brakets for the rear suspension. 7.5 8.5 and 8.8 rears.
I will keep everyone updated i expect things to be moving very quickly and thanks for the support
