you know alot more about that stuff then me, wont that fix any problems?
also have adjustable tie rod end links too (fyi)
also what does SAI mean?
i should order the FLCA next month or following. i just ordered my rear toe link (for s14) and forward rear link (for s14) today..so sorta strapped. fortunately being sonsored helps A LOT on costs so its not totally painful, but still leaves a nice dent.  good stuff. splparts.com rocks!

Ahyes. Rod-ends will definitely eliminate bind from increasing caster far beyond the stock specs.
SAI is 'steering axis inclination' (also called KPI, kingpin inclination). The axis is from the lower control arm ball-joint to the upper strut mount bearing.. basically, the 'caster' angle viewed from the front/rear of the car; how much the strut is tilted towards the engine. On our mcpherson strut cars, camber adjusted with camber plates is directly related to SAI; more camber on the plate will increase the SAI.
SAI and caster are directly related. Caster promotes the correct cambering of the wheel when its turned, while SAI reduces the effects of caster.
Just search around google for 'kingpin inclination' or 'steering axis inclination'
On an aside.. would you consider relocating the control arm mounting point to above the stock mounting point? (yep, drilling holes in the frame basically). The rod-end has a much smaller foot-print than the stock control arm so it could move up maybe as much as 1". Doing so would be the ultimate way in reducing the center of gravity, and better retaining suspension stroke while keeping the geometry decent.
I really hope the car gets aligned by a race car prep shop before its taken seriously; there is only so much that can be done with DIY alignments in a reasonable amount of time; checking bump steer, scrub radius, ackerman, caster, SAI, corner weights.. pain in the ass. And sure, once the car is initially setup, small changes are practical and expected.
