Bill,
We do offer kits with Swaybars in them.
One option is the Eibach Front & Rear Anti-roll kit.

These are very popular with our customers.
If you just have lowering springs, without new shocks... those are something I'd definitely suggest as well. It will vastly improve cornering and handling performance.....
Shocks I'd recommend are the Tokico shocks and Struts.
