Handling changes with lowering springs?

What kind of handling changes have people found with lowering springs? I recently added some Gemballa springs (also added a front strut brace and adjustable rear track arms) which lowered the car about 1" front and rear and am curious as to what I can expect when it come autocross time? On the street I noticed there is quite a bit less understeer with stock rubber but this could be my driving style and street conditions and a hundred other variables.

BTW-The car has zero toe at all four corners but the camber has increased in the rear (one side is barely in spec and the other side is barely out of spec, not sure how this happens or how to correct this?).

Well, the results are in... sort of...

The lowering springs did very little to changing the handling characteristics in terms of oversteer/understeer; however, it sure did add to the overall grip. It was an odd feeling as at no point during the autocross did I feel like I was pushing the car (very little slipping of the front or rear) but my times were fast. I won my class and got FTOD for all of the street prepared group (granted I don't remember seeing too many in this class but hey, I'll take it).

I'm anxious for the next autocross as I really want to push the cars limits and see what happens. I've got an adjustable front sway bar on order and 7mm spacers for the front simply because I'm a man and I can't leave it alone.

BTW-I did have 15mm spacers on the rear which was another reason I was shocked that I didn't push the front end more. Of course, over the years I've been able to adjust my driving style to help with the front end pushing.

BTW2-The only damping issue I found is on the street I do notice a slight underdamping when going over bumps. It isn't very noticeable but at some point in the future I may try the Bilsten sport shocks/struts.
