Been running the g-braces for a few years and like the idea of going
farther down to the frame.. is that something you also sell lab 14?
Also interested in the lower supports.. look forward to your next post
as I have been told they really flex by a few others
G-braces seem to be one of the most noticeable thing I ever did
to bracing my car.... even more than the subframe connectors
They seem to make the front end more precise to me

I believe part of the "more precise" feel after G-Brace install is due to the braces limiting twisting of the sub frame. I haven't tested that aspect yet but will eventually. Just need to decide on a good method of quantifying changes.
The plates that get welded to the upper control arm mount are for guys sticking with traditional coil spring/shock set ups. Those switching over to coilovers usually don't need the plates because they're welding supports on the outside. The plates provide a thicker section for a larger splined section for the upper control arm cross shaft studs or bolts.
The original upper control arm cross shaft mounting studs were only receiving compression and tension forces the way the factory engineers designed them. The addition of G-Brace type products forces the mounting stud to accept shear forces that try to wiggle the stud. With todays aftermarket suspensions and agressive -camber settings for auto-X and track use the point where the G-Brace attaches is spaced away from the UCA mount with shims and the cross shaft giving the shear forces leverage. The G-brace is exerting lot of side force when hitting bumps and standing on the throttle. The original design wasn't made to withstand the constant attempts to wiggle the cross shaft mounting stud.
So with the base of the cross shaft mounting stud more solid I designed adjustable supports for the stud that mount to the inside angled down to the frame horns on the same angle that force from the G-Brace is either pushing or pulling the stud. So the G-Brace is sandwiched between the immovable UCA mount and a preloaded adjustable support greatly reducing the possibility of the UCA shaft mounting stud or bolt from being able to flex or wiggle due to the shear forces.
Top pic below is a pair of the adjustable supports from the current batch. They're a bit different than the ones on my car shown in the other pics to make installation easier, allow clearance for more applications of aftermarket control arms, and to be prettier on the side that can be seen when looking under the hood. Functionally they perform the same.
