Hi Jeanius,
We always recommend to perform an alignment after adjusting the ride height on your coilover set-up. With a ride height change, both the camber and toe will change.
You can do wonders with some basic tools in your garage if you are DIY oriented. Here is a link to a fellow racer's site with a nice DIY alignment technique.

He does race alignments with a Lowes laser level and some tape measures.
Hope this helps!
