Front Suspension questions

[Cunning69]

First, let me say that I know you should stay with one manufacturer for all of your suspension pieces. But through Craigslist and some sales I have the following ready to install:

RideTech UCA’s - extra 2 degrees of positive caster
Hotchkis 2-inch lowering springs
Viking dbl adjustable shocks
CPP AFX spindles - I” taller than stock

Already installed:

Hotchkis 1.5-inch lowering rear springs
Viking dbl adjustable shocks

What I need is a pair of LCA's, if RideTech had one for coil springs I would get it, so I am looking for suggestions for LCA’s. I am cheap so I want to use the pieces I already have.
I am leaning towards:

Global West – stock suspension specs
SpeedTech – additional 4 degrees of caster

Now for the questions:
For street and spirited driving, would 4 more degrees of caster be worthwhile?
Using the SpeedTech, will the wheel still be centered in the wheel well?
Is there something else I should be considering?

Thanks for the help.
