If you've lowered the car so that the sway bar is pushing the TCA back then a number of things are happening:
1) You will have lost some caster that will make the vehicle wander a bit.
2) You will also have lost any anti-dive that was built into the suspension settings.
The answer won't just be a sway bar. IMO you need to be a bit more radical. The front suspension is very simple. You could add a goodly amount of adjustability by:
A) Fabricating an adjustable TCA
B) Adding a compression strut. The pick up point for the strut would be on the trans tunnel. The height of the bracket would determine the anti-dive so it could be made with a number of pivot points. The compression strut also determines the caster.
C) The sway bar would then be divorced from the TCA location duties so with a simple link onto the TCA it too could be made adjustable
So in conclusion, for a small limited amount of work you could have a FULLY adjustable suspension, not only for ride height, but camber, caster and roll stiffness. The end result would be as good as and in some way better than a double wishbone layout.
