Front sway bar will do more to control body roll than a xbrace or shock tower bar.

Getting more front strut travel is good advice too.

I'd just cut your losses and sell the h&r race stuff and get a ground control coilover conversion. Thats probably the most effective way to use your current struts/shocks and get usable spring rates and ride height adjustment.

I would not feel comfortable with those spring pads in an h&r spring. The coils are already very close to each other when at static compression, if you remove a coil from that stack it puts more force on the rest which may cause coil bind. You'd then end up with snap oversteer during hard corners.
